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 …

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 …

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 …

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 …

We study the functional considered in Giuliani et al.(Phys Rev B 84: 064205, 2011, Commun
Math Phys 331 (1): 333–350, 2014) and Giuliani and Seiringer (Commun Math Phys 347 …

We study a PT-symmetric scalar Euclidean field theory with a complex action, using both
theoretical analysis and lattice simulations. This model has a rich phase structure that …

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 …

The results of a combined structural and dynamical study of Cu–Zr–Al metallic glass forming
liquids are presented. Containerless high-energy x-ray scattering experiments made using …

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 …

One of the foremost objectives of statistical mechanics is the description of the
thermodynamic properties of quantum gases. Despite the great importance of this topic …
