Enhanced Kohn-Luttinger topological superconductivity in bands with nontrivial geometry
Ammar Jahin, Shi-Zeng Lin
We study the effect of the electron wavefunction on Kohn-Luttinger superconductivity. The role of the wavefunction is encoded in a complex form factor describing the topology and g…
Spontaneous vortex lattice due to orbital magnetization in valley polarized superconductors
Ammar Jahin, Shi-Zeng Lin
In this work, we study the spontaneous formation of a vortex lattice in two-dimensional valley polarized superconductors due to orbital magnetization. The screening of magnetic fie…
Chiral superconductivity from spin polarized Chern band in twisted MoTe
Cheng Xu, Nianlong Zou, Nikolai Peshcherenko +4
Superconductivity has been observed in twisted MoTe2 within the anomalous Hall metal parent state. Key signatures-including a fully spin/valley polarized normal state, anomalous Ha…
Theory of quasiparticle interference in Kitaev quantum spin liquids
Ammar Jahin, Hao Zhang, Gábor B. Halász +1
We study quasiparticle interference (QPI) in the Kitaev quantum spin liquid (QSL) for electrons tunneling into the QSL. The local tunneling conductance around a spin vacancy or loc…
