Temperature dependence of critical velocities and long time decay of supercurrents
Yongle Yu
We show that a microscopic theory of superfluidity, based on the properties of the many-body spectrum of a superfluid, can explain naturally the temperature dependence of critical…

On supersolid fraction
Yongle Yu
We present an explanation of why the observed supersolid fractions of helium solids are rather far below unity. One might observe large supersolid fraction of neon systems immersin…
