Recent developments about quantum entropic fluctuations Abstract: Since the seminal works of Evans, Searles, Gallavotti and Cohen in the early 90's the study of entropic fluctuations has encountered a fast growing interest in the last decades, and many developments at least in classical systems. Its quantum counterpart however turned out to be surprisingly challenging and brought a number of surprises. In this talk I will present some recent developments about possible extensions of these entropic fluctuations to the quantum domain. Our approach relies on quantum analogues of the Ruelle transfer operators. The talk is based on a recent series of papers in collaboration with T. Benoist, V. Jaksic, A. Panati and C.-A. Pillet. |

Numerical methods for the spectral properties of periodic Schrödinger operators
Abstract: I will talk about numerical methods for the computation of spectral properties of periodic Schrödinger operators (thermodynamic quantities, Green functions, densities of states...) and their perturbations (point defects, interfaces). At the heart is the computation of singular integrals in the Brillouin zone. |
