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…
Magnetotransport on quantum spin Hall edge coupled to bulk midgap states
Youjian Chen, Wenjin Zhao, Elliott Runburg +2
We consider magnetotransport on a helical edge of a quantum spin Hall insulator, in the presence of bulk midgap states ``side-coupled" to the edge. In the presence of a magnetic fi…
Dynamic chiral magnetic effect and Faraday rotation in macroscopically disordered helical metals
Jing Ma, D. A. Pesin
We develop an effective medium theory for electromagnetic wave propagation through gapless non-uniform systems with dynamic chiral magnetic effect. The theory allows to calculate m…
Spin and Orbital Magnetic Response on the Surface of a Topological Insulator
Yaroslav Tserkovnyak, D. A. Pesin, Daniel Loss
Coupling of the spin and orbital degrees of freedom on the surface of a strong three-dimensional insulator, on the one hand, and textured magnetic configuration in an adjacent ferr…
Density response in Weyl metals
I. Panfilov, A. A. Burkov, D. A. Pesin
We report on a study of the density response in doped Weyl semimetals or Weyl metals in the presence of an external magnetic field. We show that the applied field leads to a contri…
Interaction-Enhanced Coherence Between Two-Dimensional Dirac Layers
Inti Sodemann, D. A. Pesin, A. H. MacDonald
We estimate the strength of interaction-enhanced coherence between two graphene or topological insulator surface-state layers by solving imaginary-axis gap equations in the random…
