# Supersolidity around a critical point in dipolar Bose Einstein condensates

## TL;DR

This paper investigates the phase transition and supersolid formation in dipolar Bose-Einstein condensates, highlighting a critical point where crystallization occurs and quantum fluctuations stabilize a honeycomb supersolid phase.

## Contribution

It reveals a second order phase transition leading to a supersolid phase stabilized by quantum fluctuations in dipolar condensates.

## Key findings

- Identification of a critical point for crystallization
- Discovery of a stable honeycomb supersolid phase
- Quantum fluctuations play a key stabilizing role

## Abstract

We explore spatial symmetry breaking of a dipolar Bose Einstein condensate in the thermodynamic limit and reveal a critical point in the phase diagram at which crystallization occurs via a second order phase transition. This behavior is traced back to the significant effects of quantum fluctuations in dipolar condensates, which moreover stabilize a new supersolid phase, namely a regular honeycomb pattern with maximal modulational contrast and near-perfect superfluidity.
