Fluctuations of entropy production of a run-and-tumble particle
Daniel Maria Busiello, Amos Maritan, Deepak Gupta
Out-of-equilibrium systems continuously generate entropy, with its rate of production being a fingerprint of nonequilibrium conditions. In small-scale dissipative systems subject to thermal noise, fluctuations of entropy production are significant. Hithert ...
AMER PHYSICAL SOC2023Cavity Quantum Electrodynamics with strongly correlated fermions
This thesis presents the first cavity quantum electrodynamics experiments performed with a degenerate gas of Li with strong atom-atom interactions. The first part of this manuscript describes the design and the building of the apparatus that has been e ...
EPFL2022Optomechanical response of a strongly interacting Fermi gas
Jean-Philippe Brantut, Timo Zwettler, Victor Youri Helson, Kevin Etienne Robert Roux, Hideki Konishi
We study a Fermi gas with strong, tunable interactions dispersively coupled to a high-finesse cavity. Upon probing the system along the cavity axis, we observe a strong optomechanical Kerr nonlinearity originating from the density response of the gas to th ...
AMER PHYSICAL SOC2022Cavity-assisted preparation and detection of a unitary Fermi gas
Jean-Philippe Brantut, Victor Youri Helson, Kevin Etienne Robert Roux, Hideki Konishi
We report on the fast production and weakly destructive detection of a Fermi gas with tunable interactions in a high finesse cavity. The cavity is used both with far off-resonant light to create a deep optical dipole trap, and with near-resonant light to r ...
IOP PUBLISHING LTD2021Multiphase transport and evaporative cooling in fuel cell gas diffusion layers
The use of evaporative cooling in the gas diffusion layer (GDL) of polymer electrolyte fuel cells has been proposed as a simple yet impactful solution to simultaneously provide the functionality of cell cooling, thanks to the dissipation of the latent heat ...

2020Handedness-dependent quasiparticle interference in the two enantiomers of the topological chiral semimetal PdGa
Roland Widmer, Yi-Chiang Sun, Timur Kim, Samuel Thomas Stolz
It has recently been proposed that combining chirality with topological band theory results in a totally new class of fermions. Understanding how these unconventional quasiparticles propagate and interact remains largely unexplored so far. Here, we use sca ...
2020Determination of the Fermi surface and field-induced quasiparticle tunneling around the Dirac nodal loop in ZrSiS
Unambiguous and complete determination of the Fermi surface is a primary step in understanding the electronic properties of topical metals and semimetals, but only in a relatively few cases has this goal been realized. In this work, we present a systematic ...
2020Radiative cooling of carbon cluster anions C-2n+1(-) (n=3-5)
Radiative cooling of carbon cluster anions C(2n+1)(-)C2n+1- (n = 3-5) is investigated using the cryogenic electrostatic ion storage ring DESIREE. Two different strategies are applied to infer infrared emission on slow (milliseconds to seconds) and ultraslo ...
SPRINGER2020Zero-Index Weyl Metamaterials
Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad
Depending on the geometry of their Fermi surfaces, Weyl semimetals and their analogs in classical systems have been classified into two types. In type-I Weyl semimetals (WSMs), the conelike spectrum at the Weyl point is not tilted, leading to a pointlike c ...
