Path integrals, spontaneous localisation, and the classical limit. (arXiv:1808.04178v3 [quant-ph] UPDATED) hep-th updates on arXiv.org on 2019-2-02 2:21am GMT Authors: Bhavya Bhatt, Manish Ram Chander, Raj Patil, Ruchira Mishra, Shlok Nahar, Tejinder P. Singh We recall that in order to obtain the classical limit of quantum mechanics one needs to take the $\hbar\rightarrow 0$ limit. In addition, one also needs an explanation for the absence of… Read more →
Outline for a quantum theory of gravity. (arXiv:1901.05953v1 [gr-qc]) hep-th updates on arXiv.org on 2019-1-19 7:38am GMT Authors: Tejinder P. Singh By invoking an asymmetric metric tensor, and borrowing ideas from non-commutative geometry, string theory, and trace dynamics, we propose an action function for quantum gravity. The action is proportional to the four dimensional non-commutative curvature scalar (which is torsion dependent)… Read more →

Signs of Dynamical Dark Energy in Current Observations. (arXiv:1811.03505v3 [astro-ph.CO] UPDATED) hep-th updates on arXiv.org on 2019-1-05 2:18am GMT Authors: Joan Sola, Adria Gomez-Valent, Javier de Cruz Perez Investigations on dark energy (DE) are currently inconclusive about its time evolution. Hints of this possibility do however glow now and then in the horizon. Herein we assess the current status of dynamical dark energy… Read more →

Triply Positive Matrices and Quantum Measurements Motivated by QBism. (arXiv:1812.08762v1 [quant-ph]) quant-ph updates on arXiv.org on 2018-12-22 3:56am GMT Authors: John B. DeBrota, Christopher A. Fuchs, Blake C. Stacey We study a class of quantum measurements that furnish probabilistic representations of finite-dimensional quantum theory. The Gram matrices associated with these Minimal Informationally Complete quantum measurements (MICs) exhibit a rich structure. They are “positive”… Read more →
