Floquet codes without parent subsystem codes
Margarita Davydova, Nathanan Tantivasadakarn, Shankar Balasubramanian
We propose a new class of error-correcting dynamic codes in two and three dimensions that has no explicit connection to any parent subsystem code. The two-dimensional code, which w…
Itinerant spin polaron and metallic ferromagnetism in semiconductor moiré superlattices
Margarita Davydova, Yang Zhang, Liang Fu
Itinerant spin polaron and metallic ferromagnetism are theoretically predicted in the Mott insulator in semiconductor moiré superlattices doped below and above half filling of the…
Ubiquitous Superconducting Diode Effect in Superconductor Thin Films
Yasen Hou, Fabrizio Nichele, Hang Chi +13
The macroscopic coherence in superconductors supports dissipationless supercurrents which could play a central role in emerging quantum technologies. Accomplishing unequal supercur…
Universal Josephson diode effect
Margarita Davydova, Saranesh Prembabu, Liang Fu
We propose a universal mechanism for the Josephson diode effect in short Josephson junctions. The proposed mechanism is due to finite Cooper pair momentum and is a manifestation of…
