Identical Particle Systems : Hierarchical Spectral Reconstruction
Hovan Lee, Rémi Lefèvre, Grégoire Ithier
We identify a hierarchical symmetry structure underlying the Hilbert space of quantum systems made of identical particles. By studying the linear map between single-body and many-b…
Many Body Density of States of a system of non interacting spinless fermions
Rémi Lefèvre, Krissia Zawadzki, Grégoire Ithier
The modeling of out-of-equilibrium many-body systems requires to go beyond the low-energy physics and local densities of states. Many-body localization, presence or lack of thermal…
Generalized hyper-Ramsey-Bordé matter-wave interferometry: quantum engineering of robust atomic sensors with composite pulses
T. Zanon-Willette, D. Wilkowski, R. Lefevre +2
A new class of atomic interferences using ultra-narrow optical transitions are pushing quantum engineering control to a very high level of precision for a next generation of sensor…
SU(2) hyper-clocks: quantum engineering of spinor interferences for time and frequency metrology
T. Zanon-Willette, D. Wilkowski, R. Lefevre +2
In 1949, Ramsey's method of separated oscillating fields was elaborated boosting over many decades metrological performances of atomic clocks and becoming the standard technique fo…
Progress and perspectives on composite laser-pulses spectroscopy for high-accuracy optical clocks
Thomas Zanon-Willette, Remi Lefevre, Rémi Metzdorff +7
Probing an atomic resonance without disturbing it is an ubiquitous issue in physics. This problem is critical in high-accuracy spectroscopy or for the next generation of atomic opt…
Universal ultra-robust interrogation protocol with zero probe-field-induced frequency shift for quantum clocks and high-accuracy spectroscopy
T. Zanon-Willette, R. Lefevre, A. V. Taichenachev +1
Optical clock interrogation protocols, based on laser-pulse spectroscopy, are suffering from probe-induced frequency shifts and their variations induced by laser power. Original Hy…
