H. Landa 1, 2 A. Retzker 3 T. Schaetz 4 B. Reznik 1 Physical Review Letters, American Physical Society, 2014, 113, pp.053001 Laser cooled and trapped ions can crystallize and feature discrete solitons, that are nonlinear, topologically-protected configurations of the Coulomb crystal. Such solitons, as their continuum counterparts, can move within the crystal, while their […]

Benetti 4 Renato Pakter 4 Yan Levin 4 Stefano Ruffo 5 Physical Review E, American Physical Society, 2014, pp.062141 We explore ensemble inequivalence in long-range interacting systems by studying an XY model of classical spins with ferromagnetic and nematic coupling. We

D. S. Petrov 1 Physical Review A, American Physical Society, 2014, 90, pp.021601 We show that by coupling two hyperfine states of an atom in an optical lattice one can independently control two-, three-, and four-body on-site interactions in a non-perturbative manner. In particular, under typical conditions of current experiments one can have a purely

Francesco Caltagirone 1 Silvio Franz 2 Richard Morris 1 Lenka Zdeborová 1 Physical Review E, American Physical Society, 2014, 89, pp.012102 This work is motivated by recent progress in information theory and signal processing where the so-called ‘spatially coupled’ design of systems leads to considerably better performance. We address relevant open questions about spatially coupled

Tianyou Yi 1 Natasha Kirova 2 Serguei Brazovskii 1 International school-conference on electronic crystals: ECRYS-2014, Aug 2014, Cargèse, France. 460, pp.73, Physica B: Condensed Matter Phase transitions induced by short optical pulses is a new mainstream in studies of cooperative electronic states. Its special realization in systems with neutral-ionic transformations stands out in a way

Jad C. Halimeh 1 Anton Wöllert 1 Ian P. McCulloch 2 Ulrich Schollwöck 1 Thomas Barthel 1, 3 Physical Review A, American Physical Society, 2014, 89, pp.063603 Quantum magnetism is a fundamental phenomenon of nature. As of late, it has garnered a lot of interest because experiments with ultracold atomic gases in optical lattices can

Martin R. Evans 1 Satya N. Majumdar 2 Journal of Physics A: Mathematical and Theoretical, Institute of Physics: Hybrid Open Access, 2014, 47, pp.285001 We consider diffusion in arbitrary spatial dimension d with the addition of a resetting process wherein the diffusive particle stochastically resets to a fixed position at a constant rate $r$. We

S. Bittner 1 E. Bogomolny 2 B. Dietz 3 M. Miski-Oglu 3 A. Richter 3 Physical Review E, American Physical Society, 2014, 90, pp.052909 We present a detailed experimental study of the symmetry properties and the momentum space representation of the field distributions of a dielectric square resonator as well as the comparison with a

V. P. Michal 1 B. L. Altshuler 2 G. V. Shlyapnikov 1, 3, 4 Physical Review Letters, American Physical Society, 2014, 113, pp.045304 We consider weakly interacting bosons in a 1D quasiperiodic potential (Aubry-Azbel-Harper model) in the regime where all single-particle states are localized. We show that the interparticle interaction may lead to the many-body
