recommendations! Published in 2025 at "Journal of High Energy Physics"

DOI: 10.1007/jhep09(2025)086

Abstract: Modular Berry transport associates a geometric phase to a zero mode ambiguity in a family of modular operators. In holographic settings, this phase was shown to encode nontrivial information about the emergent spacetime geometry. We… read more here.

DOI: 10.1038/s41598-018-33258-5

Abstract: The appearance of negative longitudinal magnetoresistance (LMR) in topological semimetals such as Weyl and Dirac semimetals is understood as an effect of chiral anomaly, whereas such an anomaly is not well-defined in topological insulators. Nevertheless,… read more here.
