The density matrix renormalization group (DMRG) has become a powerful numerical method that can be applied to low-dimensional strongly correlated fermionic and bosonic …
We study the one-dimensional spin-1/2 Heisenberg chain with competing ferromagnetic nearest-neighbor J 1 and antiferromagnetic next-nearest-neighbor J 2 exchange couplings …
Abstract Lieb-Schultz-Mattis (LSM) theorems impose non-perturbative constraints on the zero-temperature phase diagrams of quantum lattice Hamiltonians (always assumed to be …

The ground-state phase diagram of a spin-1 2 XXZ chain with competing ferromagnetic nearest-neighbor (J 1< 0) and antiferromagnetic second-neighbor (J 2> 0) exchange …
Motivated by experiments on Josephson junction arrays, and cold atoms in an optical lattice in a synthetic magnetic field, we study the “fully frustrated” Bose-Hubbard model with half a …
Motivated by experiments on Josephson junction arrays in a magnetic field and ultracold interacting atoms in an optical lattice in the presence of a “synthetic” orbital magnetic field …
S Furukawa, M Sato, S Onoda - Physical review letters, 2010 - APS
We show by unbiased numerical calculations that the ferromagnetic nearest-neighbor exchange interaction stabilizes a vector spin chiral order against the quantum fluctuation in …
A Lidiak, Z Gong - Physical Review Letters, 2020 - APS
Experimental quantum simulators have become large and complex enough that discovering new physics from the huge amount of measurement data can be quite challenging …
