Dynamical Quasicondensation of Hard-Core Bosons at Finite Momenta
L. Vidmar, J. P. Ronzheimer, M. Schreiber +6
Long-range order in quantum many-body systems is usually associated with equilibrium situations. Here, we experimentally investigate the quasicondensation of strongly-interacting b…
Emergence of coherence and the dynamics of quantum phase transitions
S. Braun, M. Friesdorf, S. S. Hodgman +7
The dynamics of quantum phase transitions poses one of the most challenging problems in modern many-body physics. Here, we study a prototypical example in a clean and well-controll…
Expansion dynamics of interacting bosons in homogeneous lattices in one and two dimensions
Jens Philipp Ronzheimer, Michael Schreiber, Simon Braun +6
We experimentally and numerically investigate the expansion of initially localized ultracold bosons in homogeneous one- and two-dimensional optical lattices. We find that both dime…
Negative Absolute Temperature for Motional Degrees of Freedom
Simon Braun, Jens Philipp Ronzheimer, Michael Schreiber +4
Absolute temperature, the fundamental temperature scale in thermodynamics, is usually bound to be positive. Under special conditions, however, negative temperatures - where high-en…
Fermionic transport in a homogeneous Hubbard model: Out-of-equilibrium dynamics with ultracold atoms
Ulrich Schneider, Lucia Hackermüller, Jens Philipp Ronzheimer +8
Transport properties are among the defining characteristics of many important phases in condensed matter physics. In the presence of strong correlations they are difficult to predi…
