Quantum-classical limit of quantum correlation functions [PDF]

open access: yesThe Journal of Chemical Physics, 2004
A quantum-classical limit of the canonical equilibrium time correlation function for a quantum system is derived. The quantum-classical limit for the dynamics is obtained for quantum systems comprising a subsystem of light particles in a bath of heavy quantum particles.

Quantum correlations of light mediated by gravity [PDF]

open access: yesPhysical Review A, 2019
We propose to explore the quantum nature of gravity using the correlation of light between two optomechanical cavities, and the quantumness of the correlation is witnessed by squeezing.

Temperature Correlations of Quantum Spins [PDF]

open access: yesPhysical Review Letters, 1993
We consider isotropic XY model in the transverse magnetic field on the one dimensional lattice. Another name of the model in Heisenberg XXO model of spin 1/2.We solved long standing problem of evaluation of temperature correlations. We first represent correlation function in the model, by means of completely integrable differential equation.

Spatial Entanglement of Fermions in One-Dimensional Quantum Dots

open access: yesEntropy, 2021
The time-dependent quantum Monte Carlo method for fermions is introduced and applied in the calculation of the entanglement of electrons in one-dimensional quantum dots with several spin-polarized and spin-compensated electron configurations.

Large spatial extension of the zero-energy Yu–Shiba–Rusinov state in a magnetic field

open access: yesNature Communications, 2020
Local magnetic moments coupled to superconductors can form subgap Yu-Shiba-Rusinov states. Here the authors show that Shiba states made with an InAs nanowire quantum dot have large spatial extent, which is beneficial for making Shiba chains that are ...

Certification and applications of quantum nonlocal correlations

open access: yesJPhys Photonics, 2023
Entanglement and Einstein–Podolsky–Rosen (EPR) steering are nonlocal quantum correlations, which are relevant resources for quantum information protocols. EPR steering, or quantum steering, refers to the correlation where a party might ‘steer’, or modify,

Quantum correlations in optomechanical crystals [PDF]

open access: yesPhysical Review A, 2019
The field of optomechanics provides us with several examples of quantum photon-phonon interface. In this paper, we theoretically investigate the generation and manipulation of quantum correlations in a microfabricated optomechanical array.

Spin chain overlaps and the twisted Yangian

open access: yesJournal of High Energy Physics, 2020
Using considerations based on the thermodynamical Bethe ansatz as well as the representation theory of twisted Yangians we derive an exact expression for the overlaps between the Bethe eigenstates of the SO(6) spin chain and matrix product states built ...

Entanglement in prepare-and-measure scenarios: many questions, a few answers

open access: yesNew Journal of Physics, 2022
Entanglement and quantum communication are paradigmatic resources in quantum information science leading to correlations between systems that have no classical analogue.
