Bounds on the Pure Point Spectrum of Lattice Schrödinger Operators
Volker Bach, Walter de Siqueira Pedra, Saidakhmat Lakaev
In dimension , a variational principle for the size of the pure point spectrum of (discrete) Schrödinger operators on the hypercubic lattice $\mathbb{Z…
Universal Bounds for Large Determinants from Non-Commutative Hölder Inequalities in Fermionic Constructive Quantum Field Theory
J. -B. Bru, W. de Siqueira Pedra
Efficiently bounding large determinants is an essential step in non-relativistic fermionic constructive quantum field theory to prove the absolute convergence of the perturbation e…
The Arrow of Time in the collapse of collisionless self-gravitating systems: non-validity of the Vlasov-Poisson equation during violent relaxation
Leandro Beraldo e Silva, Walter de Siqueira Pedra, Laerte Sodré +2
The collapse of a collisionless self-gravitating system, with the fast achievement of a quasi-stationary state, is driven by violent relaxation, with a typical particle interacting…
Microscopic Conductivity of Lattice Fermions at Equilibrium - Part II: Interacting Particles
Jean-Bernard Bru, Walter de Siqueira Pedra
We apply Lieb-Robinson bounds for multi-commutators we recently derived to study the (possibly non-linear) response of interacting fermions at thermal equilibrium to perturbations…
