Semiclassical Gevrey operators and magnetic translations
Michael Hitrik, Richard Lascar, Johannes Sjoestrand +1
We study semiclassical Gevrey pseudodifferential operators acting on the Bargmann space of entire functions with quadratic exponential weights. Using some ideas of the time frequen…
Semiclassical Gevrey operators in the complex domain
Michael Hitrik, Richard Lascar, Johannes Sjoestrand +1
We study semiclassical Gevrey pseudodifferential operators, acting on exponentially weighted spaces of entire holomorphic functions. The symbols of such operators are Gevrey functi…
A direct approach to the analytic Bergman projection
Alix Deleporte, Michael Hitrik, Johannes Sjoestrand
We develop a direct approach to the semiclassical asymptotics for Bergman projections in exponentially weighted spaces of holomorphic functions, with real analytic strictly plurisu…
Weyl symbols and boundedness of Toeplitz operators
Lewis Coburn, Michael Hitrik, Johannes Sjoestrand +1
We study Toeplitz operators on the Bargmann space, with Toeplitz symbols that are exponentials of inhomogeneous quadratic polynomials. It is shown that the boundedness of such oper…
General Toeplitz matrices subject to Gaussian perturbations
Johannes Sjoestrand, Martin Vogel
We study the spectra of general Toeplitz matrices given by symbols in the Wiener Algebra perturbed by small complex Gaussian random matrices, in the regime . We…
Toeplitz band matrices with small random perturbations
Johannes Sjoestrand, Martin Vogel
We study the spectra of Toeplitz band matrices perturbed by small complex Gaussian random matrices, in the regime . We prove a probabilistic Weyl law, which pro…
