Spin dynamics of a solid-state qubit in proximity to a superconductor
Richard Monge, Tom Delord, Nicholas Proscia +11
A broad effort is underway to understand and harness the interaction between superconductors and spin-active color centers with an eye on the realization of hybrid quantum devices…
Rabi Regime of Current Rectification in Solids
Oles Matsyshyn, Francesco Piazza, Roderich Moessner +1
We investigate rectified currents in response to oscillating electric fields in systems lacking inversion and time-reversal symmetries. These currents, in second-order perturbation…
The universal shear conductivity of Fermi liquids and spinon Fermi surface states and its detection via spin qubit noise magnetometry
Jun Yong Khoo, Falko Pientka, Inti Sodemann
We demonstrate a remarkable property of metallic Fermi liquids: the transverse conductivity assumes a universal value in the quasi-static () limit for wavevectors $…
Infinite Berry Curvature of Weyl Fermi Arcs
Dennis Wawrzik, Jhih-Shih You, Jorge I. Facio +2
We show that Weyl Fermi arcs are generically accompanied by a divergence of the surface Berry curvature scaling as , where is the distance to a hot-line in the surface B…
The Berry Phase Rectification Tensor and The Solar Rectification Vector
O. Matsyshyn, Urmimala Dey, I. Sodemann +1
We introduce an operational definition of the Berry Phase Rectification Tensor as the second-order change of polarization of a material in response to an ideal short pulse of an el…
Quantum Paracrystalline Shear Modes of the Electron Liquid
Jun Yong Khoo, Po-Yao Chang, Falko Pientka +1
Unlike classical fluids, a quantum Fermi liquid can support a long-lived and propagating shear sound wave at arbitrarily small wave vectors and frequencies, reminiscent of the tran…
Nonlinear Hall Acceleration and the Quantum Rectification Sum Rule
O. Matsyshyn, I. Sodemann
Electrons moving in a Bloch band are known to acquire an anomalous Hall velocity proportional to the Berry curvature of the band which is responsible for the intrinsic linear Hall…
Symmetry and Quantum Kinetics of the Non-linear Hall Effect
Snehasish Nandy, Inti Sodemann
We argue that the static non-linear Hall conductivity can always be represented as a vector in two-dimensions and as a pseudo-tensor in three-dimensions independent of its microsco…
Strongly enhanced Berry dipole at topological phase transitions in BiTeI
Jorge I. Facio, Dmitri Efremov, Klaus Koepernik +3
Transitions between topologically distinct electronic states have been predicted in different classes of materials and observed in some. A major goal is the identification of measu…
A cascade of phase transitions in an orbitally mixed half-filled Landau level
J. Falson, D. Tabrea, D. Zhang +6
Half-filled Landau levels host an emergent Fermi-liquid which displays an instability towards pairing, culminating in a gapped even-denominator fractional quantum Hall ground state…
Current induced and interaction driven Dirac-point drag of massless quasi-relativistic fermions
Inti Sodemann
We study the quasiparticle properties of two-dimensional massless Dirac Fermions when the many-body states possess a finite momentum density in the clean limit. The lack of Galilea…
Quantum nonlinear Hall effect induced by Berry curvature dipole in time-reversal invariant materials
Inti Sodemann, Liang Fu
It is well-known that a non-vanishing Hall conductivity requires time-reversal symmetry breaking. However, in this work, we demonstrate that a Hall-like transverse current can occu…
Non-Local Transport Mediated by Spin-Supercurrents
Hua Chen, Andrew D. Kent, Allan H. MacDonald +1
In thin film ferromagnets with perfect easy-plane anisotropy, the component of total spin perpendicular to the easy plane is a good quantum number and the corresponding spin superc…
Interaction corrections to the polarization function of graphene
Inti Sodemann, Michael M. Fogler
The first-order interaction correction to the irreducible polarization function of pristine graphene is studied at arbitrary relation between momentum and frequency. The results ar…
