Unexpected two-fold symmetric superconductivity in few-layer NbSe
Alex Hamill, Brett Heischmidt, Egon Sohn +13
Two-dimensional transition metal dichalcogenides (TMDs) have been attracting significant interest due to a range of properties, such as layer-dependent inversion symmetry, valley-c…
Emergence of Chern Supermetal and Pair-Density Wave through Higher-Order Van Hove Singularities in the Haldane-Hubbard Model
Pedro Castro, Daniel Shaffer, Yi-Ming Wu +1
While advances in electronic band theory have brought to light new topological systems, understanding the interplay of band topology and electronic interactions remains a frontier…
Electrically-controllable superconducting memory effect in UTe2
Zheyu Wu, Hanyi Chen, Mengmeng Long +13
If a computer could be assembled from superconducting components, the energy efficiency would far surpass that of conventional electronics. Historic research efforts towards this g…
Theories of Superconducting Diode Effects
Daniel Shaffer, Alex Levchenko
Superconducting diode effects (SDE), both in bulk superconductors and in Josephson junctions, have garnered a lot of attention due to potential applications in classical and quantu…
Time-Reversal Invariant Topological Moiré Flatband: A Platform for the Fractional Quantum Spin Hall Effect
Yi-Ming Wu, Daniel Shaffer, Zhengzhi Wu +1
Motivated by recent observation of the quantum spin Hall effect in monolayer germanene and twisted bilayer transition-metal-dichalcogenides (TMDs), we study the topological phases…
Fluctuation-Induced Magnetoelectric Effect in Noncentrosymmetric Superconductors
Jaglul Hasan, Daniel Shaffer, Maxim Dzero +1
We study the effect of superconducting fluctuations on the spin susceptibility and NMR relaxation rate in noncentrosymmetric two-dimensional materials above the superconducting tra…
