H-theorem and Maxwell Demon in Quantum Physics. (arXiv:1804.06886v1 [quant-ph])  quant-ph updates on arXiv.org on 2018-4-21 2:11am GMT Authors: N.S. Kirsanov, A.V. Lebedev, I.A. Sadovskyy, M.V. Suslov, V.M. Vinokur, G. Blatter, G.B. Lesovik The Second Law of Thermodynamics states that temporal evolution of an isolated system occurs with non-diminishing entropy. In quantum realm, this holds for energy-isolated systems the evolution of which is described by the so-called unital… Read more →

A Finite Theory of Qubit Physics. (arXiv:1804.01734v1 [quant-ph])  quant-ph updates on arXiv.org on 2018-4-07 1:45am GMT Authors: T.N.Palmer Hardy’s axiomatic approach to the quantum theory of discrete Hilbert Spaces reveals that just one principle distinguishes it from classical probability theory: there should be continuous (and hence infinitesimal) reversible transformations between any pair of pure states – the single word `continuous’ giving… Read more →

Decoherence and Determinism in a One-Dimensional Cloud-Chamber Model  Latest Results for Foundations of Physics on 2018-4-01 12:00am GMT Abstract The hypothesis (Sparenberg et al. in EPJ Web Conf 58:01016, [1]. http://dx.doi.org/10.1051/epjconf/20135801016) that the particular linear tracks appearing in the measurement of a spherically-emitting radioactive source in a cloud chamber are determined by the (random) positions of atoms or molecules inside the… Read more →

Taking Heisenberg’s Potentia Seriously. (arXiv:1709.03595v5 [quant-ph] UPDATED)  quant-ph updates on arXiv.org on 2018-3-23 12:59am GMT Authors: R. E. Kastner, Stuart Kauffman, Michael Epperson It is argued that quantum theory is best understood as requiring an ontological duality of res extensa and res potentia, where the latter is understood per Heisenberg’s original proposal, and the former is roughly equivalent to Descartes’ ‘extended substance.’ However,… Read more →

Quantum Field Theory With No Zero-Point Energy. (arXiv:1803.05823v1 [hep-th])  hep-th updates on arXiv.org on 2018-3-17 4:45am GMT Authors: John R. Klauder Traditional quantum field theory can lead to enormous zero-point energy, which markedly disagrees with experiment. Unfortunately, this situation is built into conventional canonical quantization procedures. For identical classical theories, an alternative quantization procedure, called affine field quantization, leads to the… Read more →

On the Nature of Discrete Space-Time: The distance formula, relativistic time dilation and length contraction in discrete space-time. (arXiv:1803.03126v1 [physics.gen-ph])  gr-qc updates on arXiv.org on 2018-3-10 1:42am GMT Authors: David Crouse, Joseph Skufca In this work, the relativistic phenomena of Lorentz-Fitzgerald contraction and time dilation are derived using a modified distance formula that is appropriate for discrete space. This new distance formula… Read more →

Emergent gravity from relatively local Hamiltonians and a possible resolution of the black hole information puzzle. (arXiv:1803.00556v1 [hep-th])  hep-th updates on arXiv.org on 2018-3-02 1:31pm GMT Authors: Sung-Sik Lee In this paper, we study a possibility where gravity and time emerge from quantum matter. Within the Hilbert space of matter fields defined on a spatial manifold, we consider a sub-Hilbert space… Read more →

Would quantum entanglement be increased by anti-Unruh effect?. (arXiv:1802.07886v1 [gr-qc])  hep-th updates on arXiv.org on 2018-2-24 1:22pm GMT Authors: Taotao Li, Baocheng Zhang, Li You We study the “anti-Unruh effect” for an entangled quantum state in reference to the counterintuitive cooling previously pointed out for an accelerated detector coupled to the vacuum. We show that quantum entanglement for an initially entangled (spacelike separated)… Read more →

Gravitation in terms of observables. (arXiv:1802.02661v1 [gr-qc])  hep-th updates on arXiv.org on 2018-2-10 12:53am GMT Authors: Rodolfo Gambini, Jorge Pullin In the 1960′s, Mandelstam proposed a new approach to gauge theories and gravity based on loops. The program for gauge theories was completed for Yang–Mills theories by Gambini and Trias in the 1980′s. Gauge theories could be understood as representations of certain… Read more →
