TLDR

Crystallization of strongly interacting photons in a nonlinear optical fibre

- D. Chang, V. Gritsev, G. Morigi, V. Vuletić, M. Lukin, E. Demler
- Physics
- 11 December 2007

Understanding strongly correlated quantum systems is a central problem in many areas of physics. The collective behaviour of interacting particles gives rise to diverse fundamental phenomena such as… Expand

Relaxation of antiferromagnetic order in spin-1/2 chains following a quantum quench.

TLDR

Quench dynamics near a quantum critical point

- C. D. Grandi, V. Gritsev, A. Polkovnikov
- Physics
- 28 September 2009

We study the dynamical response of a system to a sudden change of the tuning parameter $\ensuremath{\lambda}$ starting (or ending) at the quantum critical point. In particular, we analyze the scaling… Expand

Breakdown of the adiabatic limit in low-dimensional gapless systems

- A. Polkovnikov, V. Gritsev
- Physics
- 1 June 2007

When a thermodynamic system is changed sufficiently slowly, entropy is generally conserved and the process is adiabatic, and therefore reversible. However, this adiabaticity does not seem to hold for… Expand

Quantum quenches in the anisotropic spin-\frac{1}{2} Heisenberg chain: different approaches to many-body dynamics far from equilibrium

- P. Barmettler, M. Punk, V. Gritsev, E. Demler, E. Altman
- Physics
- 10 November 2009

Recent experimental achievements in controlling ultracold gases in optical lattices open a new perspective on quantum many-body physics. In these experimental setups, it is possible to study coherent… Expand

Classifying and measuring geometry of a quantum ground state manifold

- M. Kolodrubetz, V. Gritsev, A. Polkovnikov
- Physics
- 2 May 2013

From the Aharonov-Bohm effect to general relativity, geometry plays a central role in modern physics. In quantum mechanics, many physical processes depend on the Berry curvature. However, recent… Expand

Probing quantum and thermal noise in an interacting many-body system

- S. Hofferberth, I. Lesanovsky,
+4 authors J. Schmiedmayer - Physics
- 8 October 2007

The probabilistic character of the measurement process is one of the most puzzling and fascinating aspects of quantum mechanics. In many-body systems quantum-mechanical noise reveals non-local… Expand

Fundamental noise in matter interferometers

- A. Imambekov, V. Gritsev, E. Demler
- Physics
- 28 March 2007

These lecture notes discuss two effects which contribute to the reduction of the interference fringe contrast in matter interferometers. The first effect is the shot noise arising from a finite… Expand

Full quantum distribution of contrast in interference experiments between interacting one-dimensional Bose liquids

- V. Gritsev, E. Altman, E. Demler, A. Polkovnikov
- Physics
- 21 February 2006

The existence of quantum noise is the most direct evidence for the probabilistic nature of quantum mechanics. In strongly interacting systems we expect quantum noise to reveal non-local correlations… Expand
