Worm quantum Monte-Carlo study of phase diagram of extended Jaynes-Cummings-Hubbard model
Huanhuan Wei, Jie Zhang, Sebastian Greschner +2
Herein, we study the extended Jaynes-Cummings-Hubbard model mainly by the large-scale worm quantum Monte-Carlo method to check whether or not a light supersolid phase exists in var…

Resolving the puzzle of sound propagation in liquid helium at low temperatures
Tony C. Scott, Konstantin G. Zloshchastiev
Experimental data suggests that, at temperatures below 1 K, the pressure in liquid helium has a cubic dependence on density. Thus the speed of sound scales as a cubic root of press…
