Mechanical resonances of mobile impurities in a one-dimensional quantum fluid
Thomas L. Schmidt, Giacomo Dolcetto, Christopher J. Pedder +2
We study a one-dimensional interacting quantum liquid hosting a pair of mobile impurities causing backscattering. We determine the effective retarded interaction between the two im…
Missing Shapiro steps and the -periodic Josephson effect in interacting helical electron systems
Christopher J. Pedder, Tobias Meng, Rakesh Tiwari +1
Two-particle backscattering in time-reversal invariant interacting helical electron systems can lead to the formation of quasiparticles with charge . We propose a way to detec…
Spin-orbit coupling in quasi-one-dimensional Wigner crystals
Viktoriia Kornich, Christopher J. Pedder, Thomas L. Schmidt
We study the effect of Rashba spin-orbit coupling (SOC) on the charge and spin degrees of freedom of a quasi-one-dimensional (quasi-1D) Wigner crystal. As electrons in a quasi-1D W…
Dynamic response functions and helical gaps in interacting Rashba nanowires with and without magnetic fields
Christopher Pedder, Tobias Meng, Rakesh P. Tiwari +1
A partially gapped spectrum due to the application of a magnetic field is one of the main probes of Rashba spin-orbit coupling in nanowires. Such a "helical gap" manifests itself i…
Helical gaps in interacting Rashba wires at low electron densities
Thomas L. Schmidt, Christopher J. Pedder
Rashba spin-orbit coupling and a magnetic field perpendicular to the Rashba axis have been predicted to open a partial gap ("helical gap") in the energy spectrum of noninteracting…
Electronic spin-triplet nematic with a twist
G. Hannappel, C. J. Pedder, F. Krüger +1
We analyze a model of itinerant electrons interacting through a quadrupole density-density repulsion in three dimensions. At the mean field level, the interaction drives a continuo…
