Revealing electron-lattice decoupling by Peltier thermometry and nanoscale thermal imaging in graphene
Saurabh Kumar Srivastav, Tobias Völkl, Gary Quaresima +7
Electrical currents in low-dimensional quantum materials can drive electrons far from equilibrium, creating stark imbalance between electron and lattice temperatures. Yet, no exist…
Magnetochiral anisotropy on a quantum spin Hall edge
Youjian Chen, Gary Quaresima, Wenjin Zhao +3
We develop a theory of nonlinear low-magnetic-field magnetotransport on a helical edge of a quantum spin Hall insulator due to the edge state coupling to bulk midgap states. We foc…
Collective spin oscillations in a magnetized graphene sheet
M. Agarwal, O. A. Starykh, D. A. Pesin +1
We investigate collective spin excitations of graphene electrons with short-ranged interactions and subject to the external Zeeman magnetic field. We find that in addition to the f…
Magnetic vortex control with current-induced axial magnetization in centrosymmetric Weyl materials
J. G. Yang, Yaroslav Tserkovnyak, D. A. Pesin
We consider magnetic Weyl metals as a platform to achieve current control of magnetization textures with transport currents, utilizing their underlying band geometry. We show that…
Geometric phase for nonlinear oscillators from perturbative renormalization group
D. A. Khromov, M. S. Kryvoruchko, D. A. Pesin
We formulate a renormalization group approach to a general nonlinear oscillator problem. The approach is based on the exact group law obeyed by solutions of the corresponding ordin…
Anomaly-induced sound absorption in Weyl semimetals
Ohad Antebi, D. A. Pesin, A. V. Andreev +1
We develop a semiclassical theory of sound absorption in Weyl semimetals in magnetic fields. We focus on the contribution to the absorption that stems from the existence of Berry m…
Anomalous Hall Effect in type-I Weyl metals
J. F. Steiner, A. V. Andreev, D. A. Pesin
We study the ac anomalous Hall conductivity of a Weyl semimetal with broken time-reversal symmetry. Even in the absence of free carriers these materials exhibit a "univ…
Nonperturbative interaction effects in the thermodynamics of disordered wires
D. A. Pesin, A. V. Andreev
We study nonperturbative interaction corrections to the thermodynamic quantities of multichannel disordered wires in the presence of the Coulomb interactions. Within the replica no…
Suppression of superconductivity due to non-perturbative saddle points in the nonlinear -model
D. A. Pesin, A. V. Andreev
We study superconductivity suppression due to thermal fluctuations in disordered wires using the replica nonlinear -model (). We show that in addition to the thermal phase…
Quantum Charge Fluctuations in a Superconducting Grain
M. Houzet, D. A. Pesin, A. V. Andreev +1
We consider charge quantization in a small superconducting grain that is contacted by a normal-metal electrode and is controlled by a capacitively coupled gate. At zero temperature…
Coulomb-blockade-induced bound quasiparticle states in a double-island qubit
D. A. Pesin, A. V. Andreev
We study the low temperature thermodynamic properties of a superconducting double-island qubit. For an odd number of electrons in the device, the ground state corresponds to the in…
