Anomalous dynamics and equilibration in the classical Heisenberg chain
(2021-08-26)
The search for departures from standard hydrodynamics in many-body systems has yielded a number of promising leads, especially in low dimension. Here we study one of the simplest classical interacting lattice models, the ...
Disordered flat bands on the kagome lattice
(2018-09-27)
We study two models of correlated bond- and site-disorder on the kagome lattice considering both translationally invariant and completely disordered systems. The models are shown to exhibit a perfectly at ground state band ...
Exotic superconductivity through bosons in a dynamical cluster approximation
(2015-08-07)
We study the instabilities towards (exotic) superconductivity of mixtures of spin-1/2 fermions coupled to scalar bosons on a two-dimensional square lattice with the Dynamical-Cluster-Approximation (DCA) using a numerically ...
Jammed spin liquid in the bond-disordered kagome Heisenberg antiferromagnet
(2017-06-13)
We study a class of continuous spin models with bond disorder including the kagome Heisenberg antiferromagnet. For weak disorder strength, we find discrete ground states whose number grows exponentially with system size. ...
Dynamics and energy landscape of the jammed spin-liquid
(2018-11-20)
We study the low temperature static and dynamical properties of the classical bond-disordered antiferromagnetic Heisenberg model on the kagome lattice. This model has recently been shown to host a new type of spin liquid ...
