Higher-Order Approximation of Coherent State Dynamics in Self-Interacting Quantum Field Theories
Zied Ammari, Julien Malartre, Maher Zerzeri
We study the propagation of coherent states in self-interacting bosonic quantum field theories in the semi-classical (mean-field) regime. Relying on Hepp's method and a detailed an…
Stationary phase with Cauchy singularity. A critical point of signature
Christian Klein, Johannes Sjöstrand, Maher Zerzeri
Asymptotic expressions for an integral appearing in the solution of a d-bar problem are presented. The integral is a solid Cauchy transform of a function with a rapidly oscillating…
Counter-examples to the fractal Weyl law for semiclassical resonances
Jean-Francois Bony, Setsuro Fujiie, Thierry Ramond +1
Under general assumptions, the numbers of semiclassical resonances is known to be bounded from above by a negative power of which is given by the fractal dimension of the trapp…
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…
An example of resonance instability
Jean-Francois Bony, Setsuro Fujiie, Thierry Ramond +1
We construct a semiclassical Schrödinger operator such that the imaginary part of its resonances closest to the real axis changes by a term of size when a real compactly suppor…
