Crossovers and critical scaling in the one-dimensional transverse-field Ising model

Eigenstate thermalization in the two-dimensional transverse field Ising model.

We study the onset of eigenstate thermalization in the two-dimensional transverse field Ising model (2D-TFIM) in the square lattice. We consider two nonequivalent Hamiltonians: the ferromagnetic 2D-TFIM and the antiferromagnetic 2D-TFIM in the presence of a uniform longitudinal field. We use full exact diagonalization to examine the behavior of quantum chaos indicators and of the diagonal matri...

Dynamical quantum phase transitions in the transverse-field Ising model.

A phase transition indicates a sudden change in the properties of a large system. For temperature-driven phase transitions this is related to nonanalytic behavior of the free energy density at the critical temperature: The knowledge of the free energy density in one phase is insufficient to predict the properties of the other phase. In this Letter we show that a close analogue of this behavior ...

Complete Wetting in the Three-Dimensional Transverse Ising Model

We consider a three-dimensional Ising model in a transverse magnetic field, h and a bulk field H. An interface is introduced by an appropriate choice of boundary conditions. At the point (H = 0, h = 0) spin configurations corresponding to different positions of the interface are degenerate. By studying the phase diagram near this multiphase point using quantum-mechanical perturbation theory we ...

Quantum phase transitions in the transverse one-dimensional Ising model with four-spin interactions

N = 1 SQCD and the Transverse Field Ising Model

We study the dimensions of non-chiral operators in the Veneziano limit of N = 1 supersymmetric QCD in the conformal window. We show that when acting on gaugeinvariant operators built out of scalars, the 1-loop dilatation operator is equivalent to the spin chain Hamiltonian of the 1D Ising model in a transverse magnetic field, which is a nontrivial integrable system that is exactly solvable at f...
