Ring solitons and soliton sacks in imbalanced fermionic systems
Mats Barkman, Albert Samoilenka, Thomas Winyard +1
We show that in superfluids with fermionic imbalance and uniform ground state, there are stable solitons. These solutions are formed of radial density modulations resulting in noda…
Magnetic signatures of domain walls in and superconductors: observability and what that can tell us about the superconducting order parameter
Andrea Benfenati, Mats Barkman, Thomas Winyard +3
One of the defining features of spontaneously broken time-reversal symmetry (BTRS) is the existence of domain walls, the detection of which would be strong evidence for such system…
Pair-density-wave superconductivity of faces, edges and vertices in systems with imbalanced fermions
Albert Samoilenka, Mats Barkman, Andrea Benfenati +1
We describe boundary effects in superconducting systems with Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superconducting instability, using Bogoliubov-de-Gennes and Ginzburg-Landau (GL…
Antichiral and nematicity-wave superconductivity
Mats Barkman, Alexander A. Zyuzin, Egor Babaev
Larkin-Ovchinnikov superconducting state has spontaneous modulation of Cooper pair density, while Fulde-Ferrell state has a spontaneous modulation in the phase of the order paramet…
Surface pair-density-wave superconducting and superfluid states
Mats Barkman, Albert Samoilenka, Egor Babaev
Fulde, Ferrell, Larkin, and Ovchinnikov (FFLO) predicted inhomogeneous superconducting and superfluid ground states, spontaneously breaking translation symmetries. In this Letter,…
