Topological semimetals display a range of novel transport phenomena, including enormous magnetoresistance and mobilities. Using Raman spectroscopy we have uncovered a novel mechanism for phonons to play a central role in this phenomena. Specifically we demonstrate the phonon-electron scattering time far exceeds the phonon-phonon. As such the momentum and energy typically lost to the lattice is...
Spectroscopic techniques have made remarkable progress in the past decades have played a critical role in advancing our understanding of quantum and topological materials. However, the interpretation of the spectroscopic data and information extraction processes can be highly nontrivial. In this symposium talk, we introduce machine learning as an auxiliary technique for various experiments...
Topological semimetals can host novel fermionic particles whose intriguing interactions and many-body phases can be studied experimentally. I will discuss the particularly exciting class of Rarita-Schwinger-Weyl semimetals hosting spin-3/2 electrons with linear dispersion at a four-fold band crossing point, realized experimentally in quantum materials in the last years. I will combine symmetry...
One intriguing feature of 2D hyperbolic-lattice models is that their band theories live in hypertoric Brillouin zones. The high-dimensional band structures and the dimensional mismatch between real and momentum spaces present uncharted territory beyond Euclidean topological phases. This work investigates topological phases exhibited by hyperbolic Haldane models, which are generalizations of...
