Spacing statistics for a point scatterer on the cubic three-torus
Christopher Lutsko
We study the new eigenvalues of a fixed point interaction on the cubic three-torus. Their mean-one consecutive spacings converge to a probability law independent of the interaction…
Spherical density for real semisimple groups
Christopher Lutsko
Let be a connected semisimple real Lie group with finite center and let be a tower of cocompact lattices. We prove that the weak injective radius property implies the s…
Loss of memory in the periodic Ehrenfest model with small polyhedral scatterers
Christopher Lutsko, Jens Marklof
We determine the Boltzmann--Grad limit of the Ehrenfest ``wind-tree'' model with a periodic configuration of polyhedral scatterers. The central result is a loss-of-memory effect in…
Poissonian pair correlations for the three-particle Sutherland model
Christopher Lutsko
We prove a Berry-Tabor theorem for the repulsive three-particle trigonometric Sutherland Hamiltonian. For fixed total momentum, its relative spectrum is an affine translate of the…
Improved sup-norm bounds for locally symmetric spaces
Christopher Lutsko
Let be a symmetric space of noncompact type, of dimension and rank , and let . Sarnak's local bound for an -normalized spherical joint eigenfun…
Exceptional eigenvalue density for thin groups
Christopher Lutsko
We prove a limit multiplicity conjecture of Hee Oh for principal congruence covers of geometrically finite hyperbolic manifolds, with an explicit power-saving rate. The rate is gov…
