Quantum discord and its allies: a review of recent progress
We review concepts and methods associated with quantum discord and related topics. We
also describe their possible connections with other aspects of quantum information and …

Kaleidoscope of quantum phases in a long-range interacting spin-1 chain
ZX Gong, MF Maghrebi, A Hu, M Foss-Feig… - Physical Review B, 2016 - APS
Motivated directly by recent trapped-ion quantum simulation experiments, we carry out a
comprehensive study of the phase diagram of a spin-1 chain with XXZ-type interactions that …

Phase Diagram of Bond-Alternating XXZ Chains
Phase transitions between the XY, the dimer, and the Haldane phases of the spin-1 bond-
alternating XXZ chain are studied numerically. By use of the “level spectroscopy” we …

Critical Behavior of the Antiferromagnetic Heisenberg Chain
Using the density-matrix renormalization-group technique we study the long-wavelength
properties of the spin S= 3/2 nearest-neighbor Heisenberg chain. We obtain an accurate …

Estimation of biquadratic and bicubic Heisenberg effective couplings from multiorbital Hubbard models
We studied a multi-orbital Hubbard model at half-filling for two and three orbitals per site on
a two-site cluster via full exact diagonalization, in a wide range for the onsite repulsion U …

Conformal invariance in driven diffusive systems at high currents
D Karevski, GM Schütz - Physical review letters, 2017 - APS
We consider space-time correlations in driven diffusive systems which undergo a fluctuation
into a regime with an atypically large current or dynamical activity. For a single conserved …

Convergence and quantum advantage of Trotterized MERA for strongly-correlated systems
Strongly-correlated quantum many-body systems are difficult to study and simulate
classically. Our recent work [arXiv: 2108.13401] proposed a variational quantum eigensolver …

Level statistics detect generalized symmetries
N O'Dea - arXiv preprint arXiv:2406.03983, 2024 - arxiv.org
Level statistics are a useful probe for detecting symmetries and distinguishing integrable
and non-integrable systems. I show by way of several examples that level statistics detect …
