The one dimensional (1D) spin-1/2 Heisenberg–Ising model, a prototype quantum many-
body system, has been intensively studied for many years. In this review, after a short …

Unlike the classical phase transition driven by thermal fluctuations, the quantum phase
transition arises at zero temperature when the system is tuned by a non-thermal parameter …

Abstract Integrable Quantum Field Theories can be solved exactly using bootstrap
techniques based on their elastic and factorisable S-matrix. While knowledge of the …

We report on high-resolution terahertz spectroscopic studies of quantum spin dynamics in
the quasi-one-dimensional Ising-like ferromagnet CoNb 2 O 6 and antiferromagnet BaCo 2 …

The effective spin-1/2 antiferromagnetic Heisenberg-Ising chain materials, A Co 2 V 2 O 8,
A= Sr, Ba, are a rich source of exotic fundamental phenomena and have been investigated …

The recent rapid experimental advancement in the engineering of quantum many-body
systems opens the avenue to controlled studies of fundamental physics problems via digital …

Quantum integrability emerging near a quantum critical point (QCP) is manifested by exotic
excitation spectrum that is organized by the associated algebraic structure. A well known …

The thermal deformation of the critical point action of the 2D tricritical Ising model gives rise
to an exact scattering theory with seven massive excitations based on the exceptional $ E_7 …

There has been considerable recent progress in identifying candidate materials for the
transverse-field Ising chain (TFIC), a paradigmatic model for quantum criticality. Here, we …

We investigate the nonequilibrium dynamics of the magnetization in an Ising chain
subjected to a slowly rotating transverse field. The magnetization oscillations are found to be …
