"Universal covariance formula for linear statistics on random matrices"


Abstract


I present a universal fluctuation formula for linear statistics on random matrices. Given two linear statistics A = \sum_j a(λ_j) and B = \sum_j b(λ_j) on the N eigenvalues λ of a one-cut β-ensemble of N x N random matrices, I present a formula that gives the covariance Cov(A, B) in the limit N → ∞. The formula, carrying the universal 1/β prefactor, depends on the random-matrix ensemble only through the edge points [λ_−,λ_+] of the limiting spectral density. For A = B, one recovers in some special cases the classical variance formulas by Beenakker and Dyson-Mehta. I provide two applications - the joint statistics of conductance and shot noise in ideal chaotic cavities, and a unified fluctuation relation for traces of powers of random matrices (related to enumeration problems in combinatorics).

"An optomechanical route to non-classicality"

 
Abstract


In this talk, I will review the current approach to the manipulation and control of optomechanical systems at the quantum level.

By adopting a full open-system perspective, I will illustrate the key steps necessary to achieve quantum control of massive mechanical systems by optical drives, and demonstrate the suitability of these devices to study non-equilibrium physics, quantum networking, and even exotic collapse models.
