# Thermal destabilization of self-bound ultradilute quantum droplets

@article{Wang2020ThermalDO, title={Thermal destabilization of self-bound ultradilute quantum droplets}, author={Jia Wang and Hui Hu and Xia-ji Liu}, journal={New Journal of Physics}, year={2020}, volume={22}, pages={103044} }

We theoretically investigate the temperature effect in a Bose-Bose mixture with attractive inter-species interactions, in the regime where a self-bound ultradilute quantum droplet forms due to the subtle balance between the attractive mean-field force and the repulsive force provided by Lee-Huang-Yang quantum fluctuations. We find that in contrast to quantum fluctuations, thermal fluctuations destabilize the droplet state and completely destroy it above a threshold temperature. We show that the…
