Scaling phenomena driven by inhomogeneous conditions at first-order quantum transitions
Massimo Campostrini, Jacopo Nespolo, Andrea Pelissetto +1
We investigate the effects of smooth inhomogeneities at first-order quantum transitions (FOQT), such as those arising from the presence of a space-dependent external field, which s…
Finite-size scaling at the first-order quantum transitions of quantum Potts chains
Massimo Campostrini, Jacopo Nespolo, Andrea Pelissetto +1
We investigate finite-size effects in quantum systems at first-order quantum transitions. For this purpose we consider the one-dimensional q-state Potts models which undergo a firs…
Finite-size scaling at first-order quantum transitions
Massimo Campostrini, Jacopo Nespolo, Andrea Pelissetto +1
We study finite-size effects at first-order quantum transitions (FOQTs). We show that the low-energy properties show a finite-size scaling (FSS) behavior, the relevant scaling vari…
Universal scaling effects of a temperature gradient at first-order transitions
Claudio Bonati, Massimo D'Elia, Ettore Vicari
We study the effects of smooth inhomogeneities at first-order transitions. We show that a temperature gradient at a thermally-driven first-order transition gives rise to nontrivial…
The XYZ chain with Dzyaloshinsky-Moriya interactions: from spin-orbit-coupled lattice bosons to interacting Kitaev chains
Sebastiano Peotta, Leonardo Mazza, Ettore Vicari +3
Using the density-matrix renormalization-group algorithm (DMRG) and a finite-size scaling analysis, we study the properties of the one-dimensional completely-anisotropic spin-1/2 X…
Finite-size scaling at quantum transitions
Massimo Campostrini, Andrea Pelissetto, Ettore Vicari
We develop the finite-size scaling (FSS) theory at quantum transitions, considering generic boundary conditions, such as open and periodic boundary conditions, and also the correct…
