Chirality-induced pseudo-magnetic fields, flat bands and enhancement of superconductivity
Zhiyu Dong, Leonid Levitov, Patrick A. Lee
Systems in which exchange interactions couple carrier spins to a spin texture with a net chirality exhibit a spin-dependent Aharonov-Bohm effect, where the geometric gauge field an…
Spin chirality and fermion stirring in topological bands
Archisman Panigrahi, Vladislav Poliakov, Zhiyu Dong +1
We demonstrate that in metals, both normal and superconducting, orbital currents present in the ground state when time reversal symmetry (TRS) is broken, generate spin chirality. N…
Fluctuating magnetism and Pomeranchuk effect in multilayer graphene
Ludwig Holleis, Tian Xie, Siyuan Xu +9
Magnetism typically arises from the effect of exchange interactions on highly localized fermionic wave functions in f- and d-atomic orbitals. In rhombohedral multilayer graphene (R…
Charge and spin density wave orders in field-biased Bernal bilayer graphene
Zhiyu Dong, Patrick A. Lee, Leonid Levitov
This paper aims to clarify the nature of a surprising ordered phase recently reported in biased Bernal bilayer graphene that occurs at the phase boundary between the isospin-polari…
Spin-orbit proximity in MoS/bilayer graphene heterostructures
M. Masseroni, M. Gull, A. Panigrahi +11
Van der Waals heterostructures provide a versatile platform for tailoring electronic properties through the integration of two-dimensional materials. Among these combinations, the…
Signatures of electronic ordering in transport in graphene flat bands
Archisman Panigrahi, Leonid Levitov
Recently, a wide family of electronic orders was unveiled in graphene flat bands, such as spin- and valley-polarized phases as well as nematic momentum-polarized phases, stabilized…
