#### Velocity and energy distributions in microcanonical ensembles of hard spheres

(2018-03-21)

High-temperature superconductors have different properties than conventional superconductors, one of these important properties is non-isotropic symmetry of the order parameter. In this work we present a model that shows ...

#### Crossover from anomalous to normal diffusion: truncated power-law noise correlations and applications to dynamics in lipid bilayers

(Commun. Math. Phys., 2018-01-24)

We supplement the determinantal and Pfaffian bounds of Sims and Warzel (Commun Math Phys 347:903--931, 2016) for many-body localization of quasi-free fermions, by considering the high dimensional case and complex-time ...

#### Heat production of noninteracting fermions subjected to electric fields

(Mathematical Models and Methods in Applied Sciences (M3AS), 2017-08-02)

Efficiently bounding large determinants is an essential step in non-relativistic fermionic constructive quantum field theory to prove the absolute convergence of the perturbation expansion of correlation functions in terms ...

#### Front propagation in anomalous diffusive media governed by time-fractional diffusion

(2017-05-03)

The discovery of high-temperature superconductors in 1986 represented a major experimental breakthrough (Nobel Prize 1987), but their theoretical explanation is still a subject of much debate. These materials have many ...

#### On a system of equations for the normal fluid - condensate interaction in a Bose gas

(Springer Briefs in Math. Phys., 2017)

We generalize to multi-commutators the usual Lieb–Robinson bounds for commutators. In the spirit of constructive QFT, this is done so as to allow the use of combinatorics of minimally connected graphs (tree expansions) in ...

#### Turbulence and fire-spotting effects into wild-land fire simulators

(2016-07-22)

We establish a quantum version of the classical isoperimetric inequality relating the Fisher information and the entropy power of a quantum state. The key tool is a Fisher information inequality for a state which results ...

#### Moderately Discontinuous Algebraic Topology for Metric Subanalytic Germs

(Memoirs of the American Mathematical Society, 2016-01-01)

We study a non-autonomous, non-linear evolution equation on the space of operators on a complex Hilbert space. We specify assumptions that ensure the global existence of its solutions and allow us to derive its asymptotics ...

#### The Nash Problem from a Geometric and Topological Perspective

(2016-01-01)

We generalize to multi–commutators the usual Lieb–Robinson bounds for commutators. In the spirit of constructive QFT, this is done so as to allow the use of combinatorics of minimally connected graphs (tree expan- sions) ...

#### On the geometry of strongly flat semigroups and their generalizations

(Journal des Mathematiques Pures et Appliquees, 2016-01-01)

We study the time evolution of a system of $N$ spinless fermions in $\mathbb{R}^3$ which interact through a pair potential, e.g., the Coulomb potential. We compare the dynamics given by the solution to Schrödinger's equation ...

#### Surgery formulae for the Seiberg-Witten invariant of plumbed 3-manifolds

(Letters in Mathematical Physics, 2016-01-01)

We apply Liebâ€“Robinson bounds for multi-commutators we recently derived (Bru and de Siqueira Pedra, Liebâ€“Robinson bounds for multi-commutators and applications to response theory, 2015) to study the (possibly non-linear) ...
