Chiral and topological superconductivity in isospin polarized multilayer graphene
Max Geier, Margarita Davydova, Liang Fu
A microscopic mechanism for chiral p-wave superconductivity from Coulomb repulsion is proposed for spin- and valley-polarized state of rhombohedral multilayer graphene. The superco…
Nonreciprocal superconductivity
Margarita Davydova, Max Geier, Liang Fu
We introduce the notion of nonreciprocal superconductors where inversion and time-reversal symmetries are broken, giving rise to an asymmetric energy dispersion. We demonstrate tha…
Quantum computation from dynamic automorphism codes
Margarita Davydova, Nathanan Tantivasadakarn, Shankar Balasubramanian +1
We propose a new model of quantum computation comprised of low-weight measurement sequences that simultaneously encode logical information, enable error correction, and apply logic…
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…
Josephson diode effect from Cooper pair momentum in a topological semimetal
Banabir Pal1, Anirban Chakraborty, Pranava K. Sivakumar +11
In the presence of an external magnetic field Cooper pairs in noncentrosymmetric superconductors can acquire finite momentum. Recent theory predicts that such finite-momentum pairi…
Nonlinear orbital response across topological phase transition in centrosymmetric materials
Margarita Davydova, Maksym Serbyn, Hiroaki Ishizuka
Nonlinear optical responses are often used as a probe for studying electronic properties of materials. For topological materials, studies so far focused on the photogalvanic electr…
Superscreening by a Retroreflected Hole Backflow in Tomographic Electron Fluids
Qiantan Hong, Margarita Davydova, Patrick J Ledwith +1
Electron hydrodynamics gives rise to surprising correlated behaviors in which electrons "cooperate" to quench dissipation and reduce the electric fields needed to sustain the flow.…
