Detecting chiral pairing and topological superfluidity using circular dichroism
J. M. Midtgaard, Zhigang Wu, N. Goldman +1
Realising and probing topological superfluids is a key goal for fundamental science, with exciting technological promises. Here, we show that chiral pairing in a two-dim…
Constraints on the energy spectrum of non-Hermitian models in open environments
Jonatan Melkær Midtgaard, Zhigang Wu, Yu Chen
Motivated by recent progress on non-Hermitian topological band theories, we study the energy spectrum of a generic two-band non-Hermitian Hamiltonian. We prove rigorously that the…
Stabilising Fulde-Ferrel-Larkin-Ovchinnikov Superfluidity with long-range Interactions in a mixed dimensional Bose-Fermi System
Jonatan Melkær Midtgaard, Georg M. Bruun
We analyse the stability of inhomogeneous superfluid phases in a system consisting of identical fermions confined in two layers that are immersed in a Bose-Einstein condensate (BEC…
Time-reversal invariant topological superfluids in Bose-Fermi mixtures
Jonatan Melkær Midtgaard, Zhigang Wu, G. M. Bruun
A mixed dimensional system of fermions in two layers immersed in a Bose-Einstein condensate (BEC) is shown to be a promising setup to realise topological superfluids with time-reve…
Topological superfluidity of lattice fermions inside a Bose-Einstein condensate
Jonatan Melkær Midtgaard, Zhigang Wu, G. M. Bruun
We calculate the phase diagram of identical fermions in a 2-dimensional (2D) lattice immersed in a 3D Bose-Einstein condensate (BEC). The fermions exchange density fluctuations in…
Computation of local exchange coefficients in strongly interacting one-dimensional few-body systems: local density approximation and exact results
O. V. Marchukov, E. H. Eriksen, J. M. Midtgaard +4
One-dimensional multi-component Fermi or Bose systems with strong zero-range interactions can be described in terms of local exchange coefficients and mapping the problem into a sp…
