Over the last decade impressive progress has been made in the theoretical understanding
of transport properties of clean, one-dimensional quantum lattice systems. Many physically …

The physics of one-dimensional interacting bosonic systems is reviewed. Beginning with
results from exactly solvable models and computational approaches, the concept of bosonic …

These lecture notes introduce quantum spin systems and several computational methods for
studying their ground‐state and finite‐temperature properties. Symmetry‐breaking and …

The existence of bound states of elementary spin waves (magnons) in one-dimensional
quantum magnets was predicted almost 80 years ago. Identifying signatures of magnon …

We report multipronged progress on the stochastic averaging approach to numerical
analytic continuation of imaginary-time correlation functions computed by quantum Monte …

For many years, the Luttinger liquid theory has served as a useful paradigm for the
description of one-dimensional (1D) quantum fluids in the limit of low energies. This theory is …

Inspired by classical results in integrable boundary quantum field theory, we propose a
definition of integrable initial states for quantum quenches in lattice models. They are …

Unlike conventional magnets where the magnetic moments are partially or completely static
in the ground state, in a quantum spin liquid they remain in collective motion down to the …

Almost a century ago, string states—complex bound states of magnetic excitations—were
predicted to exist in one-dimensional quantum magnets. However, despite many theoretical …

The lack of methods to experimentally detect and quantify entanglement in quantum matter
impedes our ability to identify materials hosting highly entangled phases, such as quantum …
