Crystalline ground states for classical particles
Andras Suto
Pair interactions whose Fourier transform is nonnegative and vanishes above a wave number K_0 are shown to give rise to periodic and aperiodic infinite volume ground state configur…
Thermodynamic limit and proof of condensation for trapped bosons
Andras Suto
We study condensation of trapped bosons in the limit when the number of particles tends to infinity. For the noninteracting gas we prove that there is no phase transition in any di…
Exact eigenstates for contact interactions
Andras Suto
We show that in d>1 dimensions the N-particle kinetic energy operator with periodic boundary conditions has symmetric eigenfunctions which vanish at particle encounters, and give a…
Ground state of the hard-core Bose gas on lattice I. Energy estimates
Andras Suto
We investigate the properties of the ground state of a system of interacting bosons on regular lattices with coordination number . The interaction is a pure, infinite, on-…
