Are Retrocausal Accounts of Entanglement Unnaturally Fine-Tuned?

D. Almada, K. Ch'ng, S. Kintner, B. Morrison and K.B. Wharton An explicit retrocausal model is used to analyze the general Wood-Spekkens argument [1] that any causal explanation of Bell-inequality violations must be unnaturally fine-tuned to avoid signaling. The no-signaling aspects of the model turn out to be robust under variation of the only free parameter, even as the probabilities... Read more →

A relativistic symmetrical interpretation of the Dirac equation in (1+1) dimensions

Michael B. Heaney This paper presents a new Relativistic Symmetrical Interpretation (RSI) of the Dirac equation in (1+1)D which postulates: quantum mechanics is intrinsically time-symmetric, with no arrow of time; the fundamental objects of quantum mechanics are transitions; a transition is fully described by a complex transition amplitude density with specifi ed initial and final boundary conditions; and transition amplitude densities never collapse. This RSI... Read more →

A matter wave thought experiment concerning Galilean transformations

Yamaguchi Takeshi, Tokyo Institute of Technology The Schrödinger equation is invariant under Galilean transformations. Therefore, a matter wave should undergo the Doppler effect in the same manner as a classical wave and it should be observed when the measurement apparatus, i.e., the interferometer, moves with some velocity in the laboratory reference frame. Similarly, wave-like characteristics can be expected to appear if... Read more →

What’'s wrong with the wave function?

The call to supplement the wave function with local beables is almost as old as quantum mechanics. But what exactly is the problem with the wave function as the representation of a quantum system? I canvass three potential problems with the wave function: the well-known problems of incompleteness and dimensionality, and the lesser known problem of non-locality introduced recently by...
