Searching for Coherent States, From Origins to Quantum Gravity. (arXiv:2003.11810v1 [quant-ph]) 上午8:40 | physics.hist-ph updates on arXiv.org Authors: Pierre Martin-Dussaud We discuss the notion of coherent states from three different perspectives: the seminal approach of Schroedinger, the experimental take of quantum optics, and the theoretical developments in quantum gravity. This comparative study tries to emphasise the connections between the approaches, and… Read more →

Newton’s discrete dynamics. (arXiv:2003.02702v1 [physics.class-ph]) 上午9:49 | physics.hist-ph updates on arXiv.org Authors: Søren Toxvaerd In 1687 Isaac Newton published PHILOSOPHI\AE \ NATURALIS PRINCIPIA MATHEMATICA, where the classical analytic dynamics was formulated. But Newton also formulated a discrete dynamics, which is the central difference algorithm, known as the Verlet algorithm. In fact Newton used the central difference to derive his second law….

Vacuum entanglement harvesting with a zero mode. (arXiv:2002.11790v1 [quant-ph]) 下午12:05 | Erickson Tjoa, Eduardo Martín-Martínez | quant-ph updates on arXiv.org We investigate vacuum entanglement harvesting in the presence of a zero mode. We show that, for a variety of detector models and couplings (namely, Unruh-DeWitt qubit and harmonic oscillator detectors, amplitude and derivative coupling), the results are strongly dependent on… Read more →

Joseph Polchinski: A Biographical Memoir. (arXiv:2002.02371v1 [physics.hist-ph]) 上午9:47 | physics.hist-ph updates on arXiv.org Authors: Raphael Bousso, Fernando Quevedo, Steven Weinberg Joseph Polchinski (1954-2018), one of the the leading theoretical physicists of the past 50 years, was an exceptionally broad and deep thinker. He made fundamental contributions to quantum field theory, advancing the role of the renormalization group, and to cosmology, addressing the cosmological… Read more →

A Note on Hierarchy of Quantum Measurement Incompatibilities. (arXiv:2001.11326v1 [quant-ph]) 上午9:26 | Bao-Zhi Sun, hi-Xi Wang, Xianqing Li-Jost, Shao-Ming Fei | quant-ph updates on arXiv.org The quantum measurement incompatibility is a distinctive feature of quantum mechanics. We investigate the incompatibility of a set of general measurements and classify the incompatibility by the hierarchy of compatibilities of its subsets. By using… Read more →

A Categorical Reconstruction of Quantum Theory. (arXiv:1804.02265v4 [quant-ph] UPDATED) 上午9:26 | Sean Tull | quant-ph updates on arXiv.org We reconstruct finite-dimensional quantum theory from categorical principles. That is, we provide properties ensuring that a given physical theory described by a dagger compact category in which one may `discard’ objects is equivalent to a generalised finite-dimensional quantum theory over a suitable… Read more →
