Magnetization amplification in the interlayer pairing superconductor 4Hb-TaS
Chunxiao Liu, Shubhayu Chatterjee, Thomas Scaffidi +2
A recent experiment on the bulk compound 4Hb-TaS reveals an unusual time-reversal symmetry-breaking superconducting state that possesses a magnetic memory not manifest in the n…
Probing the order parameter symmetry of two-dimensional superconductors by twisted Josephson interferometry
Jiewen Xiao, Yaar Vituri, Erez Berg
Probing the superconducting order parameter symmetry is a crucial step towards understanding the pairing mechanism in unconventional superconductors. Inspired by the recent discove…
Inhomogeneity-Induced Time-Reversal Symmetry Breaking in Cuprate Twist-Junctions
Andrew C. Yuan, Yaar Vituri, Erez Berg +2
The lowest order Josephson coupling, , between two d-wave superconductors with phase-difference across the junction vanishes when their relative orientation is r…
Multilayer graphenes as a platform for interaction-driven physics and topological superconductivity
Areg Ghazaryan, Tobias Holder, Erez Berg +1
Motivated by the recent discoveries of superconductivity in bilayer and trilayer graphene, we theoretically investigate superconductivity and other interaction-driven phases in mul…
Multiband mean-field theory of the superconductivity scenario in SrRuO
Andrew C. Yuan, Erez Berg, Steven A. Kivelson
Many seemingly contradictory experimental findings concerning the superconducting state in SrRuO can be accounted for on the basis of a conjectured accidental degeneracy be…
Magnetic memory and spontaneous vortices in a van der Waals superconductor
Eylon Persky, Anders V. Bjørlig, Irena Feldman +7
Doped Mott insulators exhibit some of the most intriguing quantum phases of matter, including quantum spin-liquids, unconventional superconductors, and non-Fermi liquid metals. Suc…
