Compass models: Theory and physical motivations
Z Nussinov, J Van Den Brink - Reviews of Modern Physics, 2015 - APS
Compass models are theories of matter in which the couplings between the internal spin (or
other relevant field) components are inherently spatially (typically, direction) dependent. A …

Medium-range atomic correlation in simple liquids. I. Distinction from short-range order
Physical properties of liquids and glasses are controlled not only by the short-range order
(SRO) in the nearest-neighbor atoms but also by the medium-range order (MRO) observed …

Medium-range atomic correlation in simple liquids. II. Theory of temperature dependence
The spatial atomic correlations in liquids and glasses extend often significantly beyond the
nearest neighbors. Such correlations, called the medium-range order (MRO), affect many …

Quantum spins on star graphs and the Kondo model
N Crampé, A Trombettoni - Nuclear Physics B, 2013 - Elsevier
We study the XX model for quantum spins on the star graph with three legs (ie, on a Y-
junction). By performing a Jordan–Wigner transformation supplemented by the introduction …

Periodic striped ground states in Ising models with competing interactions
A Giuliani, R Seiringer - Communications in Mathematical Physics, 2016 - Springer
We consider Ising models in two and three dimensions, with short range ferromagnetic and
long range, power-law decaying, antiferromagnetic interactions. We let J be the ratio …

Resolving entropy contributions in nonequilibrium transitions
We derive a functional for the entropy contributed by any microscopic degrees of freedom as
arising from their measurable pair correlations. Applicable both in and out of equilibrium, this …
