Lattice spin models for non-Abelian Chiral Spin Liquids

P. Lecheminant, A. M. Tsvelik

We suggest a class of two-dimensional lattice spin Hamiltonians describing non-Abelian SU(2) chiral spin liquids - spin-analogues of fractional non-Abelian quantum Hall states- wit…

Magnetic properties of perovskites La $_{0.7}$ Sr $_{0.3}$ Mn $_{0.7}^{3 +}$ Mn $_{0.3 - x}^{4 +}$ Ti $_{x}$ O $_{3}$ :Monte Carlo simulation versus experiments

Samia Yahyaoui, Sami Kallel, H. T. Diep

This work presents a Monte Carlo study of the phase transition in the perovskites La $_{0.7}$ Sr $_{0.3}$ Mn $_{0.7}^{3 +}$ Mn $_{0.3 - x}^{4 +}$ Ti $_{x}$ O $_{3}$ ( $x$ = 0.1, 0.2, and 0.25). We take…

Multi-triplet bound states and finite-temperature dynamics in highly frustrated quantum spin ladders

Andreas Honecker, Frédéric Mila, B. Normand

Low-dimensional quantum magnets at finite temperatures present a complex interplay of quantum and thermal fluctuation effects in a restricted phase space. While some information ab…

One-dimensional two-orbital SU(N) ultracold fermionic quantum gases at incommensurate filling: a low-energy approach

V. Bois, P. Fromholz, P. Lecheminant

We investigate the zero-temperature phase diagram of two-orbital SU(N) fermionic models at incommensurate filling which are directly relevant to strontium and ytterbium ultracold a…

Magnetic excitations in the S = 1/2 antiferromagnetic-ferromagnetic chain compound BaCu2V2O8 at zero and finite temperature

E. S. Klyushina, A. C. Tiegel, B. Fauseweh +7

Unlike most quantum systems which rapidly become incoherent as temperature is raised, strong correlations persist at elevated temperatures in $S = 1/2$ dimer magnets, as revealed by…

Optical conductivity of the Hubbard chain away from half filling

Alexander C. Tiegel, Thomas Veness, Piet E. Dargel +4

We consider the optical conductivity $σ_{1} (ω)$ in the metallic phase of the one-dimensional Hubbard model. Our results focus on the vicinity of half filling and the frequency regime…
