A talk by Frédéric Klopp
«Interacting one-dimensional quantum particles in a random field».

Abstract

Consider $$N$$ one-dimensional quantum particles in
the interval $$[0,L]$$ submitted to a random field. The
interaction is assumed to be repulsive. In the thermodynamic
limit ($$L,N\to+\infty$$, $$N/L\to\rho>0$$), we describe the
ground state and the ground state energy per particle when
$$\rho$$ is small. We will discuss both the bosonic and the
fermionic case.
