A Majorana perspective on understanding and identifying axion insulators

In topological condensed-matter systems, axion insulators are elusive excitation and active research in running to spot their signature. In this work, the authors theoretically propose a picture to characterize the surface of axion insulators and a possible detection scheme for thermal transport exp...

Sumario:In topological condensed-matter systems, axion insulators are elusive excitation and active research in running to spot their signature. In this work, the authors theoretically propose a picture to characterize the surface of axion insulators and a possible detection scheme for thermal transport experiments with a precisely half-quantized outcome.
