Fractional Little-Parks effect observed in a topological superconductor
Yufan Li, Xiaoying Xu, Shu-Ping Lee +1
In superconductors, the condensation of Cooper pairs gives rise to fluxoid quantization in discrete units of . The denominator of is the signature of electron p…
Vortices in a Monopole Superconducting Weyl Semi-metal
Canon Sun, Shu-Ping Lee, Yi Li
A monopole harmonic superconductor is a novel topological phase of matter with topologically protected gap nodes that result from the non-trivial Berry phase structure of Cooper pa…
Logarithmic singularities and quantum oscillations in magnetically doped topological insulators
Debaleena Nandi, Inti Sodemann, Kevin Shain +9
We report magnetotransport measurements on magnetically doped (Bi,Sb)Te films grown by molecular beam epitaxy. In Hallbar devices, logarithmic dependence on temperature and…
Simple lattice gauge theories at finite fermion density
Christian Prosko, Shu-Ping Lee, Joseph Maciejko
Lattice gauge theories are a powerful language to theoretically describe a variety of strongly correlated systems, including frustrated magnets, high- superconductors, and top…
Fractional Josephson effect in nonuniformly strained graphene
Shu-Ping Lee, Debaleena Nandi, Frank Marsiglio +1
Nonuniform strain distributions in a graphene lattice can give rise to uniform pseudomagnetic fields and associated pseudo-Landau levels without breaking time-reversal symmetry. We…
Interaction effects in superconductor/quantum spin Hall devices: universal transport signatures and fractional Coulomb blockade
David Aasen, Shu-Ping Lee, Torsten Karzig +1
Interfacing s-wave superconductors and quantum spin Hall edges produces time-reversal-invariant topological superconductivity of a type that can not arise in strictly 1D systems. W…
Odd-frequency superconductivity in a nanowire coupled to Majorana zero modes
Shu-Ping Lee, Roman M. Lutchyn, Joseph Maciejko
Odd-frequency superconductivity, originally proposed by Berezinskii in 1974, is an exotic phase of matter in which Cooper pairing between electrons is entirely dynamical in nature.…
Classification of spin liquids on the square lattice with strong spin-orbit coupling
Johannes Reuther, Shu-Ping Lee, Jason Alicea
Spin liquids represent exotic types of quantum matter that evade conventional symmetry-breaking order even at zero temperature. Exhaustive classifications of spin liquids have been…
Revealing topological superconductivity in extended quantum spin Hall Josephson junctions
Shu-Ping Lee, Karen Michaeli, Jason Alicea +1
Quantum spin Hall-superconductor hybrids are promising sources of topological superconductivity and Majorana modes, particularly given recent progress on HgTe and InAs/GaSb. We pro…
Electrical manipulation of Majorana fermions in an interdigitated superconductor-ferromagnet device
Shu-Ping Lee, Jason Alicea, Gil Refael
We show that a topological phase supporting Majorana fermions can form in a 2D electron gas (2DEG) adjacent to an interdigitated superconductor-ferromagnet structure. An advantage…
Possible Competing Order-Induced Fermi Arcs in Cuprate Superconductors
B. -L. Yu, J. C. F. Wang, A. D. Beyer +5
We investigate the scenario of competing order (CO) induced Fermi arcs and pseudogap in cuprate superconductors. For hole-type cuprates, both phenomena as a function of temperature…
