Observing the fate of the false vacuum with a quantum laboratory. (arXiv:2006.06003v1 [hep-th]) 上午9:31 | Steven Abel, Michael Spannowsky | quant-ph updates on arXiv.org We design and implement a quantum laboratory to experimentally observe and study dynamical processes of quantum field theories. Our approach encodes the field theory as an Ising model, which is then solved by a quantum annealer…. Read more →

Which Worldlines Represent Possible Particle Histories? 上午8:00 | Latest Results for Foundations of Physics Abstract Based on three common interpretive commitments in general relativity, I raise a conceptual problem for the usual identification, in that theory, of timelike curves as those that represent the possible histories of (test) particles in spacetime. This problem affords at least three different solutions, depending… Read more →

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 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 →

The Platonic solids and fundamental tests of quantum mechanics. (arXiv:2001.00188v1 [quant-ph]) 上午9:05 | Armin Tavakoli, Nicolas Gisin | quant-ph updates on arXiv.org The Platonic solids is the name traditionally given to the five regular convex polyhedra, namely the tetradron, the octahedron, the cube, the icosahedron and the dodecahedron. Perhaps strongly boosted by the towering historical influence of their namesake, these… Read more →

The heuristic function of duality 上午8:00 | Latest Results for Synthese Abstract I conceptualise the role of dualities in quantum gravity, in terms of their functions for theory construction. I distinguish between two functions of duality in physical practice: namely, discovering and describing ‘equivalent physics’, versus suggesting ‘new physics’. I dub these the ‘theoretical’ versus the ‘heuristic’ functions of dualities. The distinction… Read more →
