Interplay between altermagnetism and superconductivity in two dimensions: intertwined symmetries and singlet-triplet mixing
Kinga Jasiewicz, Paweł Wójcik, Michał Nowak +1
We study the interplay between altermagnetism and unconventional superconductivity for the case of two-dimensional square- and triangular-lattice systems. Our approach is based on…
Signatures of superconducting pairing driven by electron-electron interactions in moiré WSe/WSe homobilayer modelled by Hubbard Hamiltonian
Andrzej Biborski, Michał Zegrodnik
Strong evidence of unconventional superconductivity has been very recently reported experimentally in twisted transition metal dichalcogenide bilayer and gathered a significant amo…
Optimal superconductivity in twisted bilayer WSe where the Van Hove singularity crosses half-filling
Michał Zegrodnik, Waseem Akbar, Andrzej Biborski +1
The recent discovery of unconventional superconductivity has pointed to twisted WSe bilayer as a versatile platform for studying the correlated and topological phases of matter…
Superconducting gap symmetry of 2DEG at (111)-oriented LaAlO/SrTiO interface
J. Czarnecki, M. Zegrodnik, P. Wójcik
We investigate the superconducting properties of the two-dimensional electron gas at the (111) LaAlO/SrTiO interface. Using a multiorbital tight-binding model defined on a…
Scanning gate microscopy probing of anisotropic electron flow in a two dimensional electron gas at the (110) interface: A theoretical investigation
M. P. Nowak, M. Zegrodnik, D. Grzelec +3
We theoretically investigate the anisotropic dispersion features of a two dimensional electron gas at the (110) oriented interfaces, as revealed…
Interplay between topology and electron-electron interactions in the moiré MoTe/WSe heterobilayer
Palash Saha, Louk Rademaker, Michał Zegrodnik
We study, the interplay between topology and electron-electron interactions in the moiré MoTe\(_2\)/WSe\(_2\) heterobilayer. In our analysis we apply an effective two-band model wi…
