Phase Diagram of the Bosonic 2D Coulomb System

ORAL

Abstract

The system of particles in two-dimensions which interact with the long range Coulomb potential is an important model for condensed matter. This system potentially supports a rich phase diagram including hexatic and mesoscopic phases (stripes, bubbles, etc). In this talk we will extend our recent work on the distinguishable particles to a system with Bosons. We explore how the superfluid phase intersects the hexatic and Wigner crystal region and how the introduction of statistics affects conclusions about the presence of mesoscopic phases.
