Eigenstate thermalization within isolated spin-chain systems.
The thermalization phenomenon and many-body quantum statistical properties are studied on the example of several observables in isolated spin-chain systems, both integrable and generic nonintegrable.
Universal dynamics of density correlations at the transition to the many-body localized state
Within one-dimensional disordered models of interacting fermions we perform a numerical study of several dynamical density correlations, which can serve as hallmarks of the transition to the
Nonequilibrium Mass Transport in the 1D Fermi-Hubbard Model.
The sudden expansion of fermions in a homogeneous one-dimensional optical lattice is experimentally and numerically investigated, finding a reduced interaction dependence of the asymptotic expansion speed compared to bosons, which is explained by the interaction energy produced in the quench.
Typicality approach to the optical conductivity in thermal and many-body localized phases
We study the frequency dependence of the optical conductivity $\text{Re}\phantom{\rule{0.16em}{0ex}}\ensuremath{\sigma}(\ensuremath{\omega})$ of the Heisenberg spin-$\frac{1}{2}$ chain in the thermal
Spin dynamics of the block orbital-selective Mott phase
Theoretical prediction for the dynamical spin structure factor within a block-OSMP regime using the density-matrix renormalization-group method finds two dominant features: low-energy dispersive and high- energy dispersionless modes.
Density correlations and transport in models of many‐body localization
We present a review of recent theoretical results concerning the many‐body localization (MBL) phenomenon, with the emphasis on dynamical density correlations and transport quantities. They are shown
Self-consistent approach to many-body localization and subdiffusion
An analytical theory, based on the perturbative treatment of the disorder and extended into a self-consistent set of equations for the dynamical density correlations, is developed and applied to the
Heat Conductivity of the Heisenberg Spin-1/2 Ladder: From Weak to Strong Breaking of Integrability.
It is unveiled that a perturbative prediction κ∝J(⊥)(-2), based on simple golden-rule arguments and valid in the strict limit J(⍥)→0, applies to a remarkably wide range of J( ⊥), qualitatively and quantitatively.
Inelastic neutron scattering study of the anisotropic S=1 spin chain [Ni(HF2)(3−Clpyridine)4]BF4
[Ni(HF$_2$)(3-Clpyridine)$_4$]BF$_4$ (NBCT) is a one-dimensional, $S = 1$ spin chain material that shows no magnetic neutron Bragg peaks down temperatures of 0.1 K. Previous work identified NBCT to
Finite-temperature Drude weight within the anisotropic Heisenberg chain
Finite-temperature Drude weight (spin stiffness) D(T) is evaluated within the anisotropic spin-1/2 Heisenberg model on a chain using the exact diagonalization for small systems. It is shown that
