8:30 - 8:55
HARNESSING MOLECULES AS A QUANTUM INTERFACE TO STORE AND MANIPULATE ULTRASHORT OPTICAL VORTICES Université Bourgogne Europe, France Field-free molecular alignment driven by ultrashort laser pulses enables coherent control of matter on ultrafast timescales. We outline its physical basis and spectroscopic applications, then report recent progress in storing and retrieving optical orbital angular momentum in aligned media, advancing structured-light manipulation. 8:55 - 9:20
QUANTUM OPTIMAL CONTROL FOR NEXT-GENERATION QUANTUM SENSORS 1Laboratoire Collisions Agrégats Réactivité, Université de Toulouse, CNRS, 31062 Toulouse; 2Université Bourgogne Europe, CNRS, Laboratoire Interdisciplinaire Carnot de Bourgogne ICB UMR 6303, 21000 Dijon Quantum sensing enables measurements beyond classical limits, yet faces practical experimental 9:20 - 9:33
FLOQUET ENGINEERING OF TIGHT BINDING HAMILTONIAN IN MOMENTUM SPACE LATTICES Laboratoire Collisions, Agrégats, Réactivité, FeRMI, Université de Toulouse, France We generalize momentum-space lattices to all quantum resonances of the kicked rotor model. The phase and amplitude of a lattice trap are designed to simulate tight binding models thanks to first-order time-dependent perturbation theory and optimal control algorithms. An experimental study with BEC is done for Rice-Mele model and Bloch oscillations. 9:33 - 9:46
PROBING THE LOCAL DISPERSION OF K-VECTORS IN SITU WITH A BOSE-EINSTEIN CONDENSATE 1Laboratoire Kastler Brossel, France; 2Conservatoire National des Arts et Métiers We present a method to map photon momentum in situ across a laser beam using a moving Bose–Einstein condensate as a probe. Our atom interferometer measures local recoil to reconstruct a 2D map of intensity and wave-vector dispersion. Applied to a diffracted beam, it reveals extra recoil and enables wavefront and bias characterization. 9:46 - 9:59
INTERFEROMETRIC SENSING AND DICKE STATES ENGINEERING WITH SUB-SHOT NOISE SENSITIVITY ON MULTIPLE NUCLEAR SPIN-STATES OF 87SR LPL, France By exploiting the large SU(N) spin manifold of 87Sr (I=9/2), we implement multi-state Ramsey interferometers enabling simultaneous measurement of two quantities. We also aim to engineer entangled Dicke states via photoassociation on the 1S0-3P1 line, achieving sub-shot-noise phase sensitivity. 9:59 - 10:12
PROBING WEAKLY BOUND LEVELS OF A DYSPROSIUM ATOM PAIR 1Laboratoire interdisciplinaire Carnot de Bourgogne - Université Bourgogne Europe - Dijon; 2Laboratoire Aimé Cotton - Université Paris Saclay - Orsay We develop a qualitative and quantitative theoretical description of Feshbach resonances in ultracold dysprosium. We aim to explain experimentally observed resonances, especially weakly bound states, and identify mechanisms governing their width and magnetic-field dependence, focusing on an unusual s-wave state with very weak magnetic sensitivity. | |
