Correlated metallic two particle bound states in quasiperiodic chains

Sergej Flach, Mikhail Ivanchenko, Ramaz Khomeriki

Single particle states in a chain with quasiperiodic potential show a metal-insulator transition upon the change of the potential strength. We consider two particles with local int…

Spin Ice, Fractionalization and Topological Order

C. Castelnovo, R. Moessner, S. L. Sondhi

The spin ice compounds {\dys} and {\holm} are highly unusual magnets which epitomize a set of concepts of great interest in modern condensed matter physics: their low-energy physic…

Quantum stochastic description of collisions in a canonical Bose gas

Patrick Navez, Achilleas Lazarides

We derive a stochastic process that describes the kinetics of a one-dimensional Bose gas in a regime where three body collisions are important. In this situation the system becomes…

Creating Non-Maxwellian Velocity Distributions in Ultracold Plasmas

J. Castro, G. Bannasch, P. McQuillen +2

We present techniques to perturb, measure and model the ion velocity distribution in an ultracold neutral plasma produced by photoionization of strontium atoms. By optical pumping…

Intrinsic and extrinsic nonstationary field-driven processes in the spin-ice compound Dy2Ti2O7

S. Erfanifam, S. Zherlitsyn, J. Wosnitza +4

Nonequilibrium processes are probed by ultrasound waves in the spin-ice material Dy2Ti2O7 at low temperatures. The sound velocity and the sound attenuation exhibit a number of anom…

Entropic Splitter for Particle Separation

D. Reguera, A. Luque, P. S. Burada +3

We present a particle separation mechanism which induces motion of particles of different sizes in opposite directions. The mechanism is based on the combined action of a driving f…
