Room-Temperature Quantum Optomechanics and Free-Electron Quantum Optics
Quantum optics studies how photons interact with other forms of matter, the understanding of which was crucial for the development of quantum mechanics as a whole. Starting from the photoelectric effect, the quantum property of light has led to the develop ...
EPFL2024Cavity 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 ...
EPFL2022Anisotropic and nonlinear transport in microstructured 3D topological semimetals
Topological semimetals are frequently discussed as materials platforms for future electronics that exploit the remarkable properties of their quasiparticles. These ideas are mostly based on dispersion relations that mimic relativistic particles, such as We ...
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 SOC2022Intracellular recording of cardiomyocyte action potentials with nanopatterned volcano-shaped microelectrodes
Benoît Xavier Emmanuel Desbiolles
Micro-nanotechnology based multielectrode arrays have led to remarkable progress in the field of transmembrane voltage recordings of excitable cells. However, electrode geometries alone have failed to produce a cell-electrode interface that is sufficiently ...
EPFL2020GABA-mediated tonic inhibition differentially modulates gain in functional subtypes of cortical interneurons
Sean Lewis Hill, Christian Andreas Rössert, Bas-Jan Zandt, Steven Petrou
The binding of GABA (gamma-aminobutyric acid) to extrasynaptic GABA(A) receptors generates tonic inhibition that acts as a powerful modulator of cortical network activity. Despite GABA being present throughout the extracellular space of the brain, previous ...
NATL ACAD SCIENCES2020Dynamic Imaging of Lipid Membranes by Means of Water
Lipid membranes are self-assembled structures whose composition determines the properties of membranes of cells and organelles. The molecular level understanding of lipid membranes is based on spectroscopy and MD simulations of lipid monolayer systems. As ...
EPFL2019Quantized Hall Conductance of a Single Atomic Wire: A Proposal Based on Synthetic Dimensions
We propose a method by which the quantization of the Hall conductance can be directly measured in the transport of a one-dimensional atomic gas. Our approach builds on two main ingredients: (1) a constriction optical potential, which generates a mesoscopic ...
2019Travelling heteroclinic waves in a Frenkel-Kontorova chain with anharmonic on-site potential
The Frenkel-Kontorova model for dislocation dynamics from 1938 is given by a chain of atoms, where neighbouring atoms interact through a linear spring and are exposed to a smooth periodic on-site potential. A dislocation moving with constant speed correspo ...
ELSEVIER SCIENCE BV2019Membrane water for probing neuronal membrane potentials and ionic fluxes at the single cell level
Pierre Magistretti, Sylvie Roke, Orly Bagunu Tarun, Pascal Jourdain, Marie Eve Pascale Didier
Neurons communicate through electrochemical signaling within a complex network. These signals are composed of changes in membrane potentials and are traditionally measured with the aid of (toxic) fluorescent labels or invasive electrical probes. Here, we d ...
