This review article is devoted to the interplay between frustrated magnetism and quantum
critical phenomena, covering both theoretical concepts and ideas as well as recent …

The discovery of magnetism by the ancient Greeks was enabled by the natural occurrence of
lodestone–a magnetized version of the mineral magnetite. Nowadays, natural minerals …

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 transverse field Ising chain model is ideally suited for testing the fundamental ideas of
quantum phase transitions because its well-known T= 0 ground state can be extrapolated to …

The study of CoNb 2 O 6 sits at the confluence of simplicity and complexity: on one hand, the
model for Ising chains—the building blocks of CoNb 2 O 6—in a transverse field can be …

We study the nonlinear response of nonintegrable one-dimensional (1D) spin models using
infinite matrix-product state techniques. As a benchmark and demonstration of the method …

We construct a microscopic spin-exchange Hamiltonian for the quasi–one-dimensional (1D)
Ising magnet C o N b 2 O 6 that captures detailed and hitherto-unexplained aspects of its …

We calculate the dynamical spin structure factor of the generalized spin-1/2 compass spin
chain using the density matrix renormalization group. The model, also known as the twisted …

Abstract The transverse Ising magnet Hamiltonian describing the Ising chain in a transverse
magnetic field is the archetypal example of a system that undergoes a transition at a …

The quantum criticality of an Ising-like screw chain antiferromagnet SrCo 2 V 2 O 8, with a
transverse magnetic field applied along the crystalline a axis, is investigated by ultralow …
