We report results of large-scale ground-state density matrix renormalization group (DMRG) calculations on tt′-J cylinders with circumferences 6 and 8. We determine a rough phase …
AW Sandvik - AIP Conference Proceedings, 2010 - pubs.aip.org
These lecture notes introduce quantum spin systems and several computational methods for studying their ground‐state and finite‐temperature properties. Symmetry‐breaking and …
H Shao, AW Sandvik - Physics Reports, 2023 - Elsevier
We report multipronged progress on the stochastic averaging approach to numerical analytic continuation of imaginary-time correlation functions computed by quantum Monte …
The density matrix renormalization group (DMRG) is one of the most powerful numerical methods for studying two-dimensional quantum lattice systems, despite a perception that it is …
To make the transition from the quasi-long-range order in a chain of antiferromagnetically coupled S= 1/2 spins to the true long-range order that occurs in a plane, one can assemble …
In the new edition of this widely praised textbook, all the chapters have been revised and the authors have brought the work completely up to date by the addition of new material on …
In materials with strong local Coulomb interactions, simple defects such as atomic substitutions strongly affect both macroscopic and local properties of the system. A …
SR White, I Affleck - Physical Review B, 1996 - APS
Using the density matrix renormalization group and a bosonization approach, we study a spin-1/2 antiferromagnetic Heisenberg chain with near-neighbor coupling J 1 and frustrating …
