Rice U. Physicists New Type Of Quantum Material
2018/1/10
U.S. and European physicists searching for an explanation for high-temperature superconductivity were surprised when their theoretical model pointed to the existence of a never-before-seen material in...
Time separation as a hidden variable to the Copenhagen school of quantum mechanics
hidden variable Copenhagen school
2010/12/27
The Bohr radius is a space-like separation between the proton and electron in the hydrogen atom. According to the Copenhagen school of quantum mechanics, the proton is sitting in the absolute Lorentz ...
Abelian and non-abelian anyons in integer quantum anomalous Hall effect and topological phase transitions via superconducting proximity effect
Abelian non-abelian anyons integer quantum anomalous Hall effect effect
2010/12/27
We study the quantum anomalous Hall effect described by a class of two-component Haldane models on square lattices. We show that the latter can be transformed into a pseudospin triplet p+ip-wave paire...
Quantum-Gravity Induced Lorentz Violation and Dynamical Mass Generation
Quantum-Gravity Induced Lorentz Violation Dynamical Mass Generation
2010/12/27
In Ref. [1] (by J. Alexandre) a minimal extension of (3+1)-dimensional Quantum Electrodynamics has been proposed, which includes Lorentz-Violation (LV) in the form of higher-(spatial)-derivative isotr...
Quantum Aspects of Massive Gravity II: Non-Pauli-Fierz Theory
Massive Gravity II Non-Pauli-Fierz Theory
2010/12/24
We investigate the non-Pauli-Fierz (nPF) theory, a linearized massive gravity with a generic graviton mass term, which has been ignored due to a ghost in its spectrum and the resultant loss of unitari...
The quantum $H_4$ integrable system is a $4D$ system with rational potential related to the non-crystallographic root system $H_4$ with 600-cell symmetry. It is shown that the gauge-rotated $H_4$ Ham...
Quantum information transfer with nitrogen-vacancy centers coupled to a whispering-gallery microresonator
Quantum information transfer nitrogen-vacancy centers coupled whispering-gallery microresonator
2010/11/9
We propose an efficient scheme for the realization of quantum information transfer and entanglement with nitrogen-vacancy (NV) centers coupled to a high-Q microspherical resonator. We show that, base...
We apply the framework of Matrix Product States (MPS) and Projected Entangled Pair States (PEPS) and their associated parent Hamiltonians to the classification of quantum phases in one and higher dim...
Parameter Dependent Commuting Matrices, Plücker relations and Related Quantum Glass Models
Parameter Dependent Commuting Matrices Plücker relations Related Quantum Glass Models
2010/11/11
Type-I matrices were introduced recently as finite dimensional prototypes of quantum integrable systems. These matrices are linearly dependent on an "interaction" type parameter, and possess interesti...
Page has recently argued that the Born rule does not suffice for computing all probabilities in quantum cosmology. He further asserts that the Born rule's failure gives rise to the cosmological measur...
The Quantum Wave Packet and the Feynman de Broglie Bohm Propagator of the Linearized Schuch Chung Hartmann Equation along a Classical Trajetory
The Quantum Wave Packet Feynman Broglie Bohm Propagator Linearized Schuch Chung Hartmann Equation
2010/11/5
In this paper we study the quantum wave packet and the Feynman-de Broglie-Bohm propagator of the linearized Schuch-Chung-Hartmann equation along a classical trajetory.
Quantum Mechanics versus Special Relativity: A forgotten conflict
quantum mechanics quantum entanglement causation separability locality
2011/9/7
Despite the widespread assumptions on the compatibility between non-relativistic quantum mechanics and special relativity, there still remains a considerable amount of unresolved problems to which few...
The results of local measurements on some composite quantum systems cannot be reproduced classically. This impossibility, known as quantum nonlocality, represents a milestone in the foundations of qua...
Theory of quantum transport in Josephson junctions with a ferromagnetic insulator
Theory of quantum Josephson junctions ferromagnetic insulator
2010/10/27
We investigate the Josephson transport through ferromagnetic insulators (FIs) by taking into
account the band structure of FIs explicitly. Using the recursive Green’s function method, we found the fo...

Improved Loss-Tolerant Quantum Coin Flipping
2010/10/18
In this paper, we present a loss-tolerant quantum strong coin flipping protocol with bias
" 0:359. This is an improvement over Berlin et al. ’s protocol [BBBG08] which achieves a bias of 0:4. To ac...
