Hidden weak-pairing superconductivity of non-interacting anyons obeying statistics
Zheng-Duo Fan, Ashvin Vishwanath, Zijian Wang
We show that a non-interacting gas of charge- anyons with exchange statistics can superconduct through a hidden weak-pairing mechanism. Such an anyon gas arises nat…
Controlled localization of anyons in a graphene quantum Hall interferometer
Christina E. Henzinger, James R. Ehrets, Rikuto Fushio +9
Exchange statistics are a fundamental principle of quantum mechanics, dictating the symmetry of identical particle wavefunctions and thereby enabling emergent phenomena of many-bod…
Moiré in -valley square lattice: Copper- and iron-based superconductor simulation in a single device
Toshikaze Kariyado, Yusuf Wicaksono, Ashvin Vishwanath +2
Novel superconducting phases have been found in various moiré heterostructures based on hexagonal lattices. However, the archetypal high-temperature superconductors (cuprates, iro…
Minimal two band model and experimental proposals to distinguish pairing mechanisms of the high-T superconductor LaNiO
Zheng-Duo Fan, Ashvin Vishwanath
The discovery of high-T superconductivity in LaNiO has opened the door to a new route to high temperature superconductivity, distinct from that in cuprates and iron…
Spin Polarons in Flat Band Ferromagnets
Saranesh Prembabu, Rahul Sahay, Stefan Divic +1
Spin polarons are bound states of electrons and spin-flips that form above spin polarized electronic insulators.These bound states conventionally form in one of two settings: in fr…
