We study the random transverse field Ising model on a finite Cayley tree. This enables us to probe key questions arising in other important disordered quantum systems, in particular the Anderson transition and the problem of dirty bosons on the Cayle

Abinit is a material- and nanostructure-oriented package that implements density-functional theory (DFT) and many-body perturbation theory (MBPT) to find, from first principles, numerous properties including total energy, electronic structure, vibrat

${\mathrm{Sr}}_{2}{\mathrm{IrO}}_{4}$ is characterized by a large spin-orbit coupling, which gives rise to bands with strongly entangled spin and orbital characters, called ${\mathrm{J}}_{1/2}$ and ${\mathrm{J}}_{3/2}$. We use light-polarization depe

International audience; This paper is a theoretical “proof of concept” on how the on-site first-order spin–orbit coupling (SOC) can generate giant Dzyaloshinskii–Moriya interactions in binuclear transition metal complexes. This effective inte
