Non-Hermitian Boundary State Distillation with Lossy Waveguides
Walid Cherifi, Johan Carlström, Mohamed Bourennane +1
The hallmark of topological phases is their exotic boundary states. In a series of remarkable experiments it has been shown that classical analogues of these states can be engineer…

Disconnected and multiply connected spectra in the 2D attractive Hubbard model
Johan Carlström
Fermi gases and liquids display an excitation spectrum that is simply connected, ensuring closed Fermi surfaces. In strongly correlated systems like the cuprate superconductors, th…

Type-1.5 superconductivity in multicomponent systems
Egor Babaev, Johan Carlstrom, Mihail Silaev +1
In general a superconducting state breaks multiple symmetries and, therefore, is characterized by several different coherence lengths , . Moreover in multiband mate…
