The phase diagram of ultra quantum liquids
Dam Thanh Son, Mikhail Stephanov, Ho-Ung Yee
We discuss the dependence of the phase diagram of a hypothetical isotope of helium with nuclear mass less than 4 atomic mass units. We argue that with decreasing nucleus mass, the…
Effective field theory of a vortex lattice in a bosonic superfluid
Sergej Moroz, Carlos Hoyos, Claudio Benzoni +1
Using boson-vortex duality, we formulate a low-energy effective theory of a two-dimensional vortex lattice in a bosonic Galilean-invariant compressible superfluid. The excitation s…
Effective field theory for one-dimensional nonrelativistic particles with contact interaction
Soke Yuen Yong, Dam Thanh Son
We consider a field theory describing interacting nonrelativistic particles of two types, which map to each other under time reversal, with point-like interaction. We identify a ne…
