Quantum discord in photon added Glauber coherent states of -type
M. Daoud, W. Kaydi, H. El Hadfi
We investigate the influence of photon excitations on quantum correlations in tripartite Glauber coherent states of Greenberger-Horne-Zeilinger type. The pairwise correlations are…
Vacancies in the Kitaev quantum spin liquids on the 3D hyper-honeycomb lattice
G. J. Sreejith, Subhro Bhattacharjee, R. Moessner
We study the effect of adding disorder to the exactly solvable Kitaev model on the hyper-honeycomb lattice, which hosts both gapped and gapless spin liquid phases with an emergent…
Local entanglement structure across a many-body localization transition
Soumya Bera, Arul Lakshminarayan
Local entanglement between pairs of spins, as measured by concurrence, is investigated in a disordered spin model that displays a transition from an ergodic to a many-body localize…
Topological Phases of Fermionic Ladders with Periodic Magnetic Fields
Gaoyong Sun
In recent experiments bosonic [Atala et al., Nat. Phys. 10, 588 (2014), B. K. Stuhl et al., Science 349, 1514 (2015)] as well as fermionic ladders [M. Mancini et al., Science 349,…
Mixed Semiclassical Initial Value Representation Time-Averaging Propagator for Spectroscopic Calculations
Max Buchholz, Frank Grossmann, Michele Ceotto
A mixed semiclassical initial value representation expression for spectroscopic calculations is derived. The formulation takes advantage of the time-averaging filtering and the hie…
Quantum correlations beyond entanglement in a double-cavity opto-mechanical system
J. El Qars, M. Daoud, Ahl Laamara
In this paper we investigate the robustness of the quantum correlations against the environment effects in various opto-mechanical bipartite systems. For two spatially separated op…
Hilbert-Schmidt measure of pairwise quantum discord for three-qubit states
M. Daoud, R. Ahl Laamara, S. Seddik
The Hilbert-Schmidt distance between a mixed three-qubit state and its closest state is used to quantify the amount of pairwise quantum correlations in a tripartite system. Analyti…
A recursive approach for geometric quantifiers of quantum correlations in multiqubit Schrödinger cat states
M. Daoud, R. Ahl Laamara, S. Seddik
A recursive approach to determine the Hilbert-Schmidt measure of pairwise quantum discord in a special class of symmetric states of qubits is presented. We especially focus on…
Kinetic theory of spin-polarized systems in electric and magnetic fields with spin-orbit coupling: II. RPA response functions and collective modes
K. Morawetz
The spin and density response functions in the random phase approximation (RPA) are derived by linearizing the kinetic equation including a magnetic field, the spin-orbit coupling,…

The coupled kinetic equation for density and spin Wigner functions are derived including spin-orbit coupling, electric and magnetic field as well as selfconsistent Hartree meanfiel…

Zhao Liu, Abolhassan Vaezi, Cécile Repellin +1
We present the quantitative phase diagram of the bilayer bosonic fractional quantum Hall system on the torus geometry at total filling factor in the lowest Landau level. We c…
Phase Transitions in Cooperative Coinfections: Simulation Results for Networks and Lattices
Peter Grassberger, Li Chen, Fakhteh Ghanbarnejad +1
We study the spreading of two mutually cooperative diseases on different network topologies, and with two microscopic realizations, both of which are stochastic versions of an SIR…

Robin Steinigeweg, Jacek Herbrych, Frank Pollmann +1
We study the frequency dependence of the optical conductivity of the Heisenberg spin- chain in the thermal and near the transition to the many-body localiz…

For a many-particle system with long-range interactions and evolving under stochastic dynamics, we study for the first time the out-of-equilibrium fluctuations of the work done on…

We consider a generalised diffusion equation in two dimensions for modeling diffusion on a comb-like structures. We analyse the probability distribution functions and we derive the…

Enej Ilievski, Eoin Quinn, Jacopo De Nardis +1
We derive an explicit mapping between the spectra of conserved local operators of integrable quantum lattice models and the density distributions of their thermodynamic particle co…
Quantum oscillations and the Fermi-surface topology of the Weyl semimetal NbP
J. Klotz, Shu-Chun Wu, Chandra Shekhar +8
The Weyl semimetal NbP was found to exhibit topological Fermi arcs and exotic magneto-transport properties. Here, we report on magnetic quantum-oscillation measurements on NbP and…
Active processes make mixed lipid membranes either flat or crumpled
Tirthankar Banerjee, Abhik Basu
Whether live cell membranes show miscibility phase transitions (MPTs), and if so, how they fluctuate near the transitions remain outstanding unresolved issues in physics and biolog…
Density matrix renormalization group on a cylinder in mixed real and momentum space
Johannes Motruk, Michael P. Zaletel, Roger S. K. Mong +1
We develop a variant of the density matrix renormalization group (DMRG) algorithm for two-dimensional cylinders that uses a real space representation along the cylinder and a momen…
