# Absence of superfluidity in 2D dipolar Bose striped crystals

## TL;DR

This study uses computer simulations to explore the phase diagram of 2D dipolar bosons, revealing the absence of superfluidity in striped crystalline phases contrary to some theoretical predictions.

## Contribution

It provides the first detailed simulation-based analysis of the phase behavior of tilted dipolar bosons, challenging previous theories about supersolid phases.

## Key findings

- No superfluidity in striped crystalline phases.
- Presence of homogeneous superfluid and crystalline phases.
- Disagreement with recent supersolid predictions.

## Abstract

We present results of computer simulations at low temperature of a two-dimensional system of dipolar bosons, with dipole moments aligned at an arbitrary angle with respect to the direction perpendicular to the plane. The phase diagram includes a homogeneous superfluid phase, as well as triangular and striped crystalline phases, as the particle density and the tilt angle are varied. In the striped solid, no phase coherence among stripes and consequently no ``supersolid" phase is found, in disagreement with recent theoretical predictions.
