Analysis of Wigner's Set Theoretical Proof for Bell-type inequalities
Karl Hess, Hans De Raedt, Kristel Michielsen
We present a detailed analysis of the set theoretical proof of Wigner for Bell type inequalities with the following result. Wigner introduced a crucial assumption that is not relat…
Decoherence and pointer states in small antiferromagnets: A benchmark test
H. C. Donker, H. De Raedt, M. I. Katsnelson
We study the decoherence process of a four spin-1/2 antiferromagnet that is coupled to an environment of spin-1/2 particles. The preferred basis of the antiferromagnet is discussed…
Real-time broadening of non-equilibrium density profiles and the role of the specific initial-state realization
R. Steinigeweg, F. Jin, D. Schmidtke +3
The real-time broadening of density profiles starting from non-equilibrium states is at the center of transport in condensed-matter systems and dynamics in ultracold atomic gases.…
From Boole to Leggett-Garg: Epistemology of Bell-type Inequalities
Karl Hess, Hans De Raedt, Kristel Michielsen
In 1862, George Boole derived an inequality for variables, now known as Boolean variables, that in his opinion represents a demarcation line between possible and impossible experie…
Irrelevance of Bell's Theorem for experiments involving correlations in space and time: a specific loophole-free computer-example
Hans De Raedt, Kristel Michielsen, Karl Hess
John Bell is generally credited to have accomplished the remarkable "proof" that any theory of physics, which is both Einstein-local and "realistic" (counterfactually definite), re…
Counterfactual Definiteness and Bell's Inequality
Karl Hess, Hans De Raedt, Kristel Michielsen
Counterfactual definiteness must be used as at least one of the postulates or axioms that are necessary to derive Bell-type inequalities. It is considered by many to be a postulate…
Dynamics of open quantum spin systems: An assessment of the quantum master equation approach
P. Zhao, H. De Raedt, S. Miyashita +2
Data of the numerical solution of the time-dependent Schrödinger equation of a system containing one spin-1/2 particle interacting with a bath of up to 32 spin-1/2 particles is use…
Temperature- and Size-dependence of Line shape of ESR spectra of XXZ antiferromagnetic chain
Hiroki Ikeuchi, Hans De Raedt, Sylvain Bertaina +1
The ESR (Electron Spin Resonance) spectrum of the XXZ spin chain with finite length shows a double-peak structure at high temperatures around the EPR (Electron Paramagnetic Resonan…
Eigenstate Thermalization Hypothesis and Quantum Jarzynski Relation for Pure Initial States
F. Jin, R. Steinigeweg, H. De Raedt +3
Since the first suggestion of the Jarzynski equality many derivations of this equality have been presented in both, the classical and the quantum context. While the approaches and…
Quantum theory as plausible reasoning applied to data obtained by robust experiments
H. De Raedt, M. I. Katsnelson, K. Michielsen
We review recent work that employs the framework of logical inference to establish a bridge between data gathered through experiments and their objective description in terms of hu…
Quantum Decoherence and Thermalization at Finite Temperature within the Canonical Thermal State Ensemble
M. A. Novotny, F. Jin, S. Yuan +3
We study measures of decoherence and thermalization of a quantum system in the presence of a quantum environment (bath) . The entirety is prepared in a canonical t…
Finite-Difference Time-Domain Simulation for Three-dimensional Polarized Light Imaging
Miriam Menzel, Markus Axer, Hans De Raedt +1
Three-dimensional Polarized Light Imaging (3D-PLI) is a promising technique to reconstruct the nerve fiber architecture of human post-mortem brains from birefringence measurements…
