Liquid Drop Model for Nuclear Matter in the Low Density Limit

Rupert L. Frank, Mathieu Lewin, Robert Seiringer

We consider the liquid drop model with a positive background density in the thermodynamic limit. We prove a two-term asymptotics for the ground state energy per unit volume in the…

The generalized Wehrl entropy bound in quantitative form

Rupert L. Frank, Fabio Nicola, Paolo Tilli

Lieb and Carlen have shown that mixed states with minimal Wehrl entropy are coherent states. We prove that mixed states with almost minimal Wehrl entropy are almost coherent states…

Weighted CLR type bounds in two dimensions

Rupert L. Frank, Ari Laptev, Larry Read

We derive weighted versions of the Cwikel-Lieb-Rozenblum inequality for the Schrödinger operator in two dimensions with a nontrivial Aharonov-Bohm magnetic field. Our bounds captur…

Sharp inequalities for coherent states and their optimizers

Rupert L. Frank

We are interested in sharp functional inequalities for the coherent state transform related to the Wehrl conjecture and its generalizations. This conjecture was settled by Lieb in…

The Scott conjecture for large Coulomb systems: a review

Rupert L. Frank, Konstantin Merz, Heinz Siedentop

We review some older and more recent results concerning the energy and particle distribution in ground states of heavy Coulomb systems. The reviewed results are asymptotic in natur…

A sharp criterion for zero modes of the Dirac equation

Rupert L. Frank, Michael Loss

It is shown that is a necessary condition for the existence of a nontrivial solution of the Dirac equation $γ\cdot (-i\nabla -A)ψ= 0…
