Energy gap of quantum spin glasses: a projection quantum Monte Carlo study
L. Brodoloni, G. E. Astrakharchik, S. Giorgini +1
The performance of quantum annealing for combinatorial optimization is fundamentally limited by the minimum energy gap encountered at quantum phase transitions. We investigate…

The Bose polaron as thermometer of a trapped Bose gas: a quantum Monte Carlo study
Tomasz Wasak, Gerard Pascual, Gregory E. Astrakharchik +2
Quantum impurities interacting with quantum environments offer unique insights into many-body systems. Here, we explore the thermometric potential of a neutral impurity immersed in…
