Tuesday, April 9, – 3: Qyantique modeling is shown to be a powerful tool to obtain the properties of the spin ensembles coupled to a resonator. Monday, October 15, – 3: In order to model their intricate interplay with the laser-induced plasma processes, they have been implemented within the particle-in-cell code calder developed at CEA.

We first investigate theoretically the coupling of a resonator to a continuous distribution electridynamique inhomogeneously broadened emitters. Igor Diniz 1 AuthorId: We find that their coherence depends crucially on the shape of the distribution and not only on its width. In a second part, we consider positron generation in the collision between a GeV electron bunch issued from a laser-wake eld accelerator and a counterpropagating laser pulse. Simulations show that this original method can be faster and have higher fidelity than methods currently used quantiique circuit QED.

Tuesday, August 21, – Wednesday, May 11, – 1: Have you forgotten your login? In a first part, we study these QED processes in the interaction of an ultra-intense laser with a micrometric overdense target. Mathieu Lobet 1, 2 Details. In a third part, we analyze a prospective electrodymamique of astrophysical interest, consisting in the collision between two dense pair plasmas produced from solid targets irradiated at Wcm-2 showing a fast-growing magnetic lamentation instability amplified by intense synchrotron emission.

These quantum electrodynamic processes, which until recently could only be explored on large-scale particle accelerators, can greatly alter the “standard” mechanisms of laser-plasma interaction, and therefore its overall energy budget.

Tuesday, January 8, – 4: Electrodynamique quantique des atomes artificiels supraconducteurs. We discuss the influence of the emitters inhomogeneous broadening on the existence and on the coherence properties of the polaritonic peaks.


This system supports a diamond-shape artificial atom where we define logical and ancilla qubits coupled through a cross-Kerr like term. This thesis focuses on two problems quantiique circuit quantum electrodynamics.

Depending on the logical qubit state, the ancilla is resonantly or dispersively coupled to the resonator, leading to a large contrast in the transmitted microwave signal amplitude. This PhD thesis is concerned with the regime of extreme-intensity laser-matter interaction qyantique should be accessed on upcoming multi-petawatt facilities e.

Quantum electrodynamics in superconducting artificial atoms.

Igor Diniz 1 Details. Mathieu Lobet 1, 2 AuthorId: Studying this formalism is strongly motivated by recent proposals to use collections of emitters as quantum memories for individual excitations. Such systems benefit from the collective enhancement of the interaction strength, while keeping the relaxation properties of a single emitter.
