Deep learning for the design of non-Hermitian topolectrical circuits
Xi Chen, Jinyang Sun, Xiumei Wang, Hengxuan Jiang, Dandan Zhu, and Xingping Zhou
Author(s): Xi Chen, Jinyang Sun, Xiumei Wang, Hengxuan Jiang, Dandan Zhu, and Xingping Zhou

Non-Hermitian topological phases can produce some remarkable properties, compared with their Hermitian counterpart, such as the breakdown of conventional bulk-boundary correspondence and the non-Hermitian topological edge mode. Here, we introduce several algorithms with multilayer perceptron (MLP), …

Two-electron photoemission spectroscopy in topological superconductors
Ka Ho Wong, Ameya Patwardhan, Peter Abbamonte, Fahad Mahmood, and Dirk K. Morr
Author(s): Ka Ho Wong, Ameya Patwardhan, Peter Abbamonte, Fahad Mahmood, and Dirk K. Morr

We demonstrate that the photoelectron counting rate, ${P}^{(2)}$, measured in two-electron coincidence spectroscopy experiments, provides insight into the nature of topological superconductivity. In particular, we show that the spin dependence of ${P}^{(2)}$ allows one to detect superconducting spin…

Nonlocal thermoelectric detection of interaction and correlations in edge states
Alessandro Braggio, Matteo Carrega, Björn Sothmann, and Rafael Sánchez
Author(s): Alessandro Braggio, Matteo Carrega, Björn Sothmann, and Rafael Sánchez

Nonequilibrium effects in interacting systems are among the most challenging problems in condensed-matter physics. Here, a quantum Hall-based setup where a simple thermoelectrical DC measurement extracts information on the interaction-mediated thermal equilibration processes is presented. It’s shown how thermal relaxation between edge states, initially at different temperatures, evolves in terms of the interaction strength, the length of the interaction region, and the temperature differences, finding a universal behavior. The predictions between Landau-Fermi liquid and Tomonaga-Luttinger liquid are compared. Finally, a new circuit theory is applied, demonstrating how the cross-correlations crucially affect the energy-relaxation process and the electron-distribution evolution.
