A two-dimensional realization of the parity anomaly
Nehal Mittal, Tristan Villain, Mathis Demouchy +4
Quantum anomalies arise when symmetries of a classical theory cannot be preserved upon quantization, leading to unconventional topological responses. A prominent example is the par…
Breathing and Fission of Magnetic Multi-Solitons
G. Brochier, Y. Li, S. Wattellier +5
We report the deterministic experimental realization and controlled fission of magnetic multi-soliton states in a uniform quasi-one-dimensional immiscible two-component Bose gas. W…
Multicomponent condensates: a flexible platform for soliton physics
Franco Rabec, Jérôme Beugnon, Jean Dalibard +1
We present a series of experimental investigations on binary mixtures of Bose-Einstein condensates. Our focus lies on the regime where the interaction parameters place the system a…
Superfluid Fraction of a 2D Bose-Einstein Condensate in a Triangular Lattice
F. Rabec, G. Brochier, S. Wattellier +5
We experimentally investigate the superfluid properties of a two-dimensional, weakly interacting Bose-Einstein condensate in the zero-temperature regime, when it is subjected to a…
Bisognano-Wichmann Hamiltonian for the entanglement spectroscopy of fractional quantum Hall states
A. Nardin, R. Lopes, M. Rizzi +2
We study the Bisognano-Wichmann Hamiltonian for fractional quantum Hall states defined on a sphere and explore its relationship with the entanglement Hamiltonian associated to the…
Bloch Oscillations of a Soliton in a 1D Quantum Fluid
F. Rabec, G. Chauveau, G. Brochier +3
The motion of a quantum system subjected to an external force often defeats our classical intuition. A celebrated example is the dynamics of a single particle in a periodic potenti…
