Invited Speaker / Conférencier(ère) invité(e)

The nature of dark matter, and the origin of the matter-antimatter imbalance of the universe, are intriguing open questions in high-energy physics and cosmology. The breakdown of time-reversal symmetry (T) at ultra-high energy scales is believed to underlie one or both of these puzzles. However, these energy scales lie far above the reach of particle colliders. Fortunately, we can probe the...

Quantum sensors achieve measurement precisions well beyond classical bounds, though in order to reach such sensitivities methods for quantum optimal control are often employed, particularly in systems where decoherence is important; however, optimizing the control of quantum sensors is made difficult by the fact that not all Hamiltonian parameters are known. Here we investigate the use of...

Betavoltaic energy conversion uses a semiconductor device to convert beta radiation (high-energy electrons) from a radioisotope to generate electrical power. Current challenges include designing semiconductor structures that minimize backscattered electrons, non-radiative carrier recombination, and maximize minority carrier diffusion lengths. Diamond is a promising material to tackle these...

Time-dependent response of strong-field driven multi-electron correlated photorecombination process is investigated by employing the perturbed trajectory measurement method. It is well-known that field-free xenon has a very large photoionization cross section around the photon energy of 80 eV as giant plasmonic resonance due to the electron-electron interaction between 4d and 5p orbitals....
