Effective Lagrangian of unitary Fermi gas from expansion
Andrei Kryjevski
Using expansion technique proposed in \cite{Nishida:2006br} we derive an effective Lagrangian (Ginzburg-Landau-like functional) of the degenerate unitary Fermi gas to…
Goldstone boson currents in a kaon condensed CFL phase
Andreas Gerhold, Thomas Schaefer, Andrei Kryjevski
We study the stability of the kaon condensed color-flavor locked (CFL) phase of dense quark matter with regard to the formation of a non-zero Goldstone boson current. In the kaon c…
Polarized fermions in the unitarity limit
Gautam Rupak, Thomas Schaefer, Andrei Kryjevski
We consider a polarized Fermi gas in the unitarity limit. Results are calculated analytically up to next-to-leading order in an expansion about d=4 spatial dimensions. We find a fi…
Spontaneous Superfluid Current Generation in CFL at Nonzero Strange Quark Mass
Andrei Kryjevski
We find that for large enough strange quark mass, kaon condensed CFL phase of asymptotically dense 3 flavor quark matter is unstable with respect to spon…
An Effective Theory for Baryons in the CFL Phase
Andrei Kryjevski, Thomas Schaefer
We study the effective field theory for fermions in the color-flavor locked (CFL) phase of high density QCD. The effective theory contains a flavor nonet of baryons interacting wit…
CFL Phase of High Density QCD at Non Zero Strange Quark Mass
Andrei Kryjevski, Daisuke Yamada
We compute free energy of quark matter at asymptotically high baryon number density in the presence of non zero strange quark mass including dynamics of pseudo Nambu-Goldstone boso…
