Phase-Noise-Induced Heating in Optical Lattices
Jean Paul Nohra, Cyprien Daix, Joris Verstraten +5
We experimentally and theoretically study the origin of heating in optical lattices by disentangling the respective roles of intensity and phase noise depending on the lattice para…
Probing the Fermi Sea Topology in a Quantum Gas
Cyprien Daix, Pok Man Tam, Maxime Dixmerias +5
Pauli's exclusion principle forces fermions to occupy distinct quantum states, creating a filled region of momentum space at low temperature, the Fermi sea, whose topology governs…
Universal Random Matrix Behavior of a Fermionic Quantum Gas
Maxime Dixmerias, Giuseppe Del Vecchio Del Vecchio, Cyprien Daix +6
The pursuit of universal governing principles is a foundational endeavor in physics, driving breakthroughs from thermodynamics to general relativity and quantum mechanics. In 1951,…
Observing Spatial Charge and Spin Correlations in a Strongly-Interacting Fermi Gas
Cyprien Daix, Maxime Dixmerias, Yuan-Yao He +5
In this work, we explore two-dimensional attractive Fermi gases at the microscopic level by probing spatial charge and spin correlations in situ. Using atom-resolved continuum quan…
Mutual friction and vortex Hall angle in a strongly interacting Fermi superfluid
Nicola Grani, Diego Hernández-Rajkov, Cyprien Daix +8
The motion of a quantized vortex is intimately connected with its microscopic structure and the elementary excitations of the surrounding fluid. In this work, we investigate the tw…
Fluctuation thermometry of an atom-resolved quantum gas: Beyond the fluctuation-dissipation theorem
Maxime Dixmerias, Joris Verstraten, Cyprien Daix +3
Thermometry is essential for studying many-body physics with ultracold atoms. Accurately measuring low temperatures in these systems, however, remains a significant challenge due t…
