Exploring the Kibble-Zurek mechanism with homogeneous Bose gases
J. Beugnon, N. Navon
Out-of-equilibrium phenomena is a subject of considerable interest in many fields of physics. Ultracold quantum gases, which are extremely clean, well-isolated and highly controlla…
Emergence of a Turbulent Cascade in a Quantum Gas
Nir Navon, Alexander L. Gaunt, Robert P. Smith +1
In the modern understanding of turbulence, a central concept is the existence of cascades of excitations from large to small lengthscales, or vice-versa. This concept was introduce…
Connecting Berezinskii-Kosterlitz-Thouless and BEC phase transitions by tuning interactions in a trapped gas
Richard J. Fletcher, Martin Robert-de-Saint-Vincent, Jay Man +4
We study the critical point for the emergence of coherence in a harmonically trapped two-dimensional Bose gas with tuneable interactions. Over a wide range of interaction strengths…
Critical Dynamics of Spontaneous Symmetry Breaking in a Homogeneous Bose gas
Nir Navon, Alexander L. Gaunt, Robert P. Smith +1
We explore the dynamics of spontaneous symmetry breaking in a homogeneous system by thermally quenching an atomic gas with short-range interactions through the Bose-Einstein phase…
The Equation of State of a Low-Temperature Fermi Gas with Tunable Interactions
Nir Navon, Sylvain Nascimbène, Frédéric Chevy +1
Interacting fermions are ubiquitous in nature and understanding their thermodynamics is an important problem. We measure the equation of state of a two-component ultracold Fermi ga…
