Superconductivity in moiré transition metal dichalcogenide bilayers: comparison of two distinct theoretical approaches
Waseem Akbar, MichaÅ Zegrodnik
Superconductivity has recently been observed in moiré transition-metal dichalcogenide bilayers. Here, we investigate the superconducting state in twisted WSe using two complem…
Emergent Quantum Valley Hall Insulator from Electron Interactions in Transition-Metal Dichalcogenide Heterobilayers
Palash Saha, MichaÅ Zegrodnik
We explore the emergence of topological phases in moiré MoTe/WSe bilayer, highlighting the crucial role of spin-orbit coupling and Coulomb interactions at two holes per mo…
Interplay between altermagnetism and superconductivity in two dimensions: intertwined symmetries and singlet-triplet mixing
Kinga Jasiewicz, PaweŠWójcik, MichaŠNowak +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, MichaÅ 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
MichaÅ 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…
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…
