High-Temperature Quantum Oscillations of a Non-equilibrium Non-Fermi Liquid
Oles Matsyshyn, Li-kun Shi, Inti Sodemann Villadiego
A periodically driven Fermi gas coupled to a simple boson bath reaches a non-equilibrium steady-state occupation with sharp non-analyticities at certain momenta. Here, we demonstra…
Optical conductivity and band gap in the double-Weyl candidate SrSi2 at ambient pressure
L. Z. Maulana, A. A. Tsirlin, E. Uykur +4
We probe the possible double-Weyl state in cubic SrSi2 using optical spectroscopy. The complex optical conductivity was measured in a frequency range from 70 to 22 000 cm-1 at temp…
Edge Reconstruction in a Quantum Spin Hall Insulator
Rahul Soni, Matthias Thamm, Gonzalo Alvarez +2
We study interaction-driven edge reconstruction in a quantum spin Hall insulator described by the Bernevig-Hughes-Zhang model with Kanamori-Hubbard interactions using the real-spac…
On the influence of reference sample properties on magnetic force microscopy calibrations
Baha Sakar, Christopher Habenschaden, Sibylle Sievers +1
Magnetic force microscopy (MFM) allows the characterization of magnetic stray field distributions with high sensitivity and spatial resolution. Based on a suitable calibration proc…
Comment on "Electric conductivity of graphene: Kubo model versus a nonlocal quantum field theory model (arXiv:2403.02279v3)"
M. Bordag, N. Khusnutdinov, G. L. Klimchitskaya +1
Recently, Rodriguez-Lopez, Wang, and Antezza [Phys. Rev. B v.111, 115428 (2025)] compared the theoretical descriptions of electric conductivity of graphene given by the Kubo model…
Algebraic Exact Solution for Driven Landau Levels in Two-dimensional Electron Gases
Li-kun Shi
Controlling quantum systems with time-dependent fields opens avenues for engineering novel states of matter and exploring non-equilibrium phenomena. Landau levels in two-dimensiona…
