    It is argued that the result assumption of Bohm's theory, which says that particle configurations represent measurement results, contradicts the predictions of the Schroedinger equation.

    The measurement problem revisited
    Synthese 196 (1): 299-311. 2019.
    It has been realized that the measurement problem of quantum mechanics is essentially the determinate-experience problem, and in order to solve the problem, the physical state representing the measurement result is required to be also the physical state on which the mental state of an observer supervenes. This necessitates a systematic analysis of the forms of psychophysical connection in the solutions to the measurement problem. In this paper, I propose a new, mentalistic formulation of the mea…Read more

    The many-worlds interpretation of quantum mechanics is based on three key assumptions: the completeness of the physical description by means of the wave function, the linearity of the dynamics for the wave function, and multiplicity. In this paper, I argue that the combination of these assumptions may lead to a contradiction. In order to avoid the contradiction, we must drop one of these key assumptions.

    In collapse theories of quantum mechanics such as the GRW theory, the measurement result is represented by the post-measurement state which is still a superposition of different result branches, although the modulus squared of the amplitude of one result branch is close to one. This leads to the tails problem. In this paper, I present a new analysis of the tails problem of collapse theories, and suggest a more complete solution to the problem. First, I argue that the tails problem exists not onl…Read more

    It has been widely thought that the ontology of quantum mechanics is real, physical fields. In this paper, I will present a new argument against the field ontology of quantum mechanics by analyzing one-body systems such as an electron. First, I argue that if the physical entity described by the wave function of an electron is a field, then this field is massive and charged. Next, I argue that if a field is massive and charged, then any two parts of the field in space will have gravitational and …Read more

    From Intrinsic Value to the Emotion of Wonder
    Environmental Ethics 40 (1): 81-91. 2018.
    Since environmental ethics research started in China in the 1980s, it has been deeply influenced by environmental ethics theory in the United States. Some Chinese environmental philosophers have adopted the key concept of intrinsic value to construct Chinese environmental ethics. However, in recent decades, the concept of intrinsic value has been criticized by scholars in both the United States and China. Many Chinese have found that environmental ethics in the United States that is founded on t…Read more

    Healey recently argued that a version of the extended Wigner's friend Gedankenexperiment due to Masanes establishes a contradiction between the universal applicability of unitary quantum theory and the assumption of definite outcomes [Found. Phys. 48, 1568 ]. In this Comment, I show that Healey's analysis is problematic and his conclusion is not true.

    It is shown that the combination of unitary quantum theory and special relativity may lead to a contradiction when considering the EPR correlations in different inertial frames in a Gedankenexperiment. This result seems to imply that either unitary quantum theory is wrong or if unitary quantum theory is right then there must exist a preferred Lorentz frame.

    It has been debated whether protective measurement implies the reality of the wave function. In this paper, I present a new analysis of the relationship between protective measurement and the reality of the wave function. First, I briefly introduce protective measurements and the ontological models framework for them. Second, I give a simple proof of Hardy's theorem in terms of protective measurements. It shows that when assuming the ontic state of the protected system keeps unchanged during a p…Read more

    Psychophysical supervenience requires that the mental properties of a system cannot change without the change of its physical properties. In this paper, I argue that the Everett interpretation of quantum mechanics or Everett's theory seems to violate the principle of psychophysical supervenience. In order to be consistent with our experience, the theory assumes psychophysical supervenience in each world, including our world. However, this permits the possibility that under certain unitary time e…Read more

    In collapse theories of quantum mechanics, there exist quantum observers who are observers being in a superposition of different result branches. In this paper, I analyze the mental state of a quantum observer. First, I argue that the mental state of a quantum observer is not the usual state of recording one of the results in the superposition, but it is definite. Second, I argue that the mental state of a quantum observer is determined by both the amplitudes and relative phases of the result br…Read more

    Recently the first protective measurement has been realized in experiment [Nature Phys. 13, 1191 ], which can measure the expectation value of an observable from a single quantum system. This raises an important and pressing issue of whether protective measurement implies the reality of the wave function. If the answer is yes, this will improve the influential PBR theorem [Nature Phys. 8, 475 ] by removing auxiliary assumptions, and help settle the issue about the nature of the wave function. In…Read more

    The role of the light postulate in special relativity is reexamined. The existing theory of relativity without light shows that one can deduce Lorentz-like transformations with an undetermined invariant speed based on homogeneity of space and time, isotropy of space and the principle of relativity. However, since the transformations can be Lorentzian or Galilean, depending on the finiteness of the invariant speed, a further postulate is needed to determine the speed in order to establish a real …Read more

    It is argued that if the relative configuration of Bohmian particles represents the measurement result, then the predictions of Bohm's theory may be inconsistent with the Born rule in some situations.

    Everett's theory assumes the completeness of the description by the wave function, the linearity of the dynamics for the wave function, and multiplicity. In this paper, I argue that these three assumptions of Everett's theory may lead to the violation of psychophysical supervenience.

    The meaning of the wave function has been a hot topic of debate since the early days of quantum mechanics. Recent years have witnessed a growing interest in this long-standing question. Is the wave function ontic, directly representing a state of reality, or epistemic, merely representing a state of knowledge, or something else? If the wave function is not ontic, then what, if any, is the underlying state of reality? If the wave function is indeed ontic, then exactly what physical state does it …Read more

    The existing psi-ontology theorems are based on a simplified assumption of the ontological models framework, according to which when a measurement is performed the behaviour of the measuring device is determined by the ontic state of the measured system immediately before the measurement. In this paper, I give an argument for the reality of the wave function in terms of protective measurements under a more reasonable assumption, according to which the behaviour of the measuring device during a m…Read more

    The ontological status of the wave function in quantum mechanics is usually analyzed in the context of conventional impulsive measurements. These analyses are always based on some nontrivial assumptions, e.g. a preparation independence assumption is needed to prove the PBR theorem. In this paper, we point out that the reality of the wave function can be argued without resorting to nontrivial assumptions by analyzing protective measurements, by which one can measure the expectation values of obse…Read more

    Can Chinese Philosophy Embrace Wilderness?
    Environmental Ethics 39 (2): 147-159. 2017.
    Because of rapid industrialization and urbanization, many natural resources in China have increasingly been degraded. In response to this situation, China haslearned from the United States about one of its best ideas, national parks. This idea triggers many philosophical questions. How is wilderness interpreted in theUnited States? What are the philosophical foundations for the concept of intrinsic value in wilderness? Can Chinese philosophy accept wilderness? To answer these questions, the idea…Read more

    On Uffink's criticism of protective measurements
    Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 44 (4): 513-518. 2013.
    Protective measurement is a new measuring method introduced by Aharonov, Vaidman, and Anandan, with the aim of measuring the expectation value of an observable on a single quantum system, even if the system is initially not in an eigenstate of the measured observable. According to these authors, this feature of protective measurements favors a realistic interpretation of the wave function. These claims were challenged by Uffink. He argued that only observables that commute with the system's Hami…Read more

    Science has made a mighty advance since it originated in ancient Greece more than 2500 years ago. Yet we still live in Plato's cave today; we think everything around us moves continuously, but continuous motion is merely a shadow of real motion. This book will lead you to walk out the cave along a logical and comprehensible road. After passing Zeno's arrow, Newton's inertia, Einstein's light, and Schrodinger's cat, you will reach the real world, where every thing in the universe, whether it is a…Read more

    We discuss a new realistic interpretation of quantum mechanics based on discontinuous motion of particles. The historical and logical basis of discontinuous motion of particles is given. It proves that if there exists only one kind of physical reality---particles, then the realistic motion of particles described by quantum mechanics should be discontinuous motion. We further denote that protective measurement may provide a direct method to confirm the existence of discontinuous motion of particl…Read more

    We study the possible connection between self-consciousness and quantum process. It is shown that the self-consciousness function can help to measure the collapse time of wave function under some condition, while the usual physical device without self-consciousness can't. Furthermore, we show that the observer with self-consciousness can distinguish the definite state and the superposition of definite states under some stronger condition. This provides a practical physical method to differentiat…Read more

    Quantum collapse, consciousness and superluminal communication
    Foundations Of Physics Letters 17 (2): 167-182. 2004.
    The relation between quantum collapse, consciousness and superluminal communication is analyzed. As we know, quantum collapse, if exists, can result in the appearance of quantum nonlocality, and requires the existence of a pre- ferred Lorentz frame. This may permit the realization of quantum superluminal communication (QSC), which will no longer result in the usual causal loop in case of the existence of a preferred Lorentz frame. The possibility of the existence of QSC is further analyzed under…Read more
