Quantum Correlations beyond Entanglement and Discord. [PDF]
Physical Review Letters, 2020 Dissimilar notions of quantum correlations have been established, each being motivated through particular applications in quantum information science and each competing for being recognized as the most relevant measure of quantumness.

CORRELATIONS IN QUANTUM PHYSICS [PDF]
International Journal of Modern Physics B, 2012 We provide a historical perspective of how the notion of correlations has evolved within quantum physics. We begin by reviewing Shannon's information theory and its first application in quantum physics, due to Everett, in explaining the information conveyed during a quantum measurement.

Creating mirror–mirror quantum correlations in optomechanics [PDF]
European Physical Journal D : Atomic, Molecular and Optical Physics, 2020 We study the transfer of quantum correlations between two movable mirrors of two Fabry-Pérot cavities separated via broadband squeezed light and coupled via photon hopping process.

Vital role of magnetocrystalline anisotropy in cubic chiral skyrmion hosts
npj Quantum Materials, 2021 Magnetic anisotropy is anticipated to govern the formation of exotic spin textures reported recently in cubic chiral magnets, like low-temperature tilted conical and skyrmion lattice (SkL) states and metastable SkLs with various lattice geometry ...

On exact overlaps in integrable spin chains
Journal of High Energy Physics, 2020 We compute the exact overlaps between integrable boundary states and on-shell Bethe states for integrable spin chains. Our method is based on the coordinate Bethe Ansatz and does not rely on the “rotation trick” of the corresponding lattice model.

Optimal tests of genuine multipartite nonlocality
New Journal of Physics, 2022 We propose an optimal and efficient numerical test for witnessing genuine multipartite nonlocality based on a geometric approach. In particular, we consider two non-equivalent models of local hidden variables, namely the Svetlichny and the no-signaling ...

Post-quantum nonlocality in the minimal triangle scenario
New Journal of Physics, 2023 We investigate network nonlocality in the triangle scenario when all three parties have no input and binary outputs. Through an explicit example, we prove that this minimal scenario supports nonlocal correlations compatible with no-signaling and ...

Antiferromagnetic magnons as highly squeezed Fock states underlying quantum correlations [PDF]
Physical review B, 2019 Employing the concept of two-mode squeezed states from quantum optics, we demonstrate a revealing physical picture for the antiferromagnetic ground state and excitations.

T T ¯ $$ T\overline{T} $$ -deformation and long range spin chains
Journal of High Energy Physics, 2020 We point out that two classes of deformations of integrable models, developed completely independently, have deep connections and share the same algebraic origin. One class includes the T T ¯ $$ T\overline{T} $$ -deformation of 1+1 dimensional integrable
