High-spin d 7 Co (II) compounds have recently been identified as possible platforms for
realizing highly anisotropic and bond-dependent couplings featured in quantum-compass …

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 …

Two-dimensional coherent spectroscopy (2DCS) is a nonlinear spectroscopy technique
capable of identifying whether apparent continua in linear response are made out of …

The Ising chain in a transverse field is a paradigmatic model for a host of physical
phenomena, including spontaneous symmetry breaking, quantum criticality and duality …

The identification of microscopic systems describing the low-energy properties of correlated
materials has been a central goal of spectroscopic measurements. We demonstrate how two …

Motivated by the on-going discussion on the nature of magnetism in the quantum Ising chain
CoNb2O6, we present a first-principles-based analysis of its exchange interactions with …
