Hall viscosity and conductivity of two-dimensional chiral superconductors
Félix Rose, Omri Golan, Sergej Moroz
We compute the Hall viscosity and conductivity of non-relativistic two-dimensional chiral superconductors, where fermions pair due to a short-range attractive potential, e.g. $p+\m…
Helical spin texture in a thin film of superfluid He
Tomas Brauner, Sergej Moroz
We consider a thin film of superfluid He under conditions that stabilize the A-phase. We show that in the presence of a uniform superflow and an external magnetic field perpe…
Screening and Topological Order in Thin Superconducting Films
E. C. Marino, D. Niemeyer, Van Sérgio Alves +2
We derive an effective two-dimensional low-energy theory for thin superconducting films coupled to a three-dimensional fluctuating electromagnetic field. Using this theory we discu…
Multiply quantized vortices in fermionic superfluids: angular momentum, unpaired fermions, and spectral asymmetry
Abhinav Prem, Sergej Moroz, Victor Gurarie +1
We compute the orbital angular momentum of an s-wave paired superfluid in the presence of an axisymmetric multiply quantized vortex. For vortices with winding number $|k| > 1…
Topological order, symmetry, and Hall response of two-dimensional spin-singlet superconductors
Sergej Moroz, Abhinav Prem, Victor Gurarie +1
Fully gapped two-dimensional superconductors coupled to dynamical electromagnetism are known to exhibit topological order. In this work, we develop a unified low-energy description…
Functional renormalization for trion formation in ultracold fermion gases
S. Floerchinger, R. Schmidt, S. Moroz +1
The energy spectrum for three species of identical fermionic atoms close to a Feshbach resonance is computed by use of a nonperturbative flow equation. Already a simple truncation…
