Observation of superconducting vortices carrying a temperature-dependent fraction of the flux quantum
Yusuke Iguchi, Ruby Shi, Kunihiro Kihou +4
The magnetic response is a state-defining property of superconductors. The magnetic flux penetrates type-II bulk superconductors by forming quantum vortices when the enclosed magne…
Demonstration of skyrmions in three-band superconductors by self-consistent solutions to a Bogoliubov-de Gennes model
Andrea Benfenati, Mats Barkman, Egor Babaev
Topological defects, such as magnetic-flux-carrying quantum vortices determine the magnetic response of superconductors and hence are of fundamental importance. Here, we show that…
Elevated critical temperature at BCS superconductor-band insulator interfaces
Mats Barkman, Albert Samoilenka, Andrea Benfenati +1
We consider the interface between a Bardeen-Cooper-Schrieffer superconductor and non-superconducting band insulator. We show that under certain conditions, such interfaces can have…
Reply to the Comment on "Surface Pair-Density-Wave Superconducting and Superfluid States"
Mats Barkman, Andrea Benfenati, Albert Samoilenka +1
The recent Comment by Vorontsov [arXiv:2007.13696] claims that surface pair-density-wave superconductivity with critical temperature higher than the bulk FFLO critical temperature…
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,…
