Long Josephson junctions with exciton-polariton condensates
A. Muñoz Mateo, Y. G. Rubo, L. A. Toikka
We demonstrate the possibility to build stable Josephson -junction stripes with exciton-polariton condensates. The stability of the -junction between arbitrary long polariton…
Disorder-induced two-body localised state in interacting quantum walks
L. A. Toikka
We observe the onset of non-ergodicity from ballistic propagation of a two-body bound state in an interacting discrete-time quantum walk (DTQW) due to time-dependent disorder in th…
Non-Abelian Majorana fermions in topological -wave Fermi superfluids
L. A. Toikka
By solving the Bogoliubov--De Gennes equations analytically, we derive the fermionic zero-modes satisfying the Majorana property that exist in vortices of a two-dimensional -wav…
Many-body dynamical localisation of coupled quantum kicked rotors
L. A. Toikka, A. Andreanov
The quantum motion of coupled kicked rotors is mapped to an interacting -particle Anderson-Aubry-Andr tight-binding problem supporting many-body localised (MBL) phases. I…
Necessary and sufficient conditions for flat bands in -dimensional -band lattices with complex-valued nearest-neighbour hopping
L. A. Toikka, A. Andreanov
We formulate the necessary and sufficient conditions for the existence of dispersionless energy eigenvalues (so-called `flat bands') and their associated compact localized eigensta…
Accurate projective two-band description of topological superfluidity in spin-orbit-coupled Fermi gases
J. Brand, L. A. Toikka, U. Zülicke
The interplay of spin-orbit coupling and Zeeman splitting in ultracold Fermi gases gives rise to a topological superfluid phase in two spatial dimensions that can host exotic Major…
