Title: Weyl semimetals in torsional spacetime Abstract: Weyl semimetals necessarily break the time-reversal or/and inversion symmetry. In the presence of spatially varying time-reversal or inversion symmetry breaking fields, we show that the Weyl fermions live in emergent torsional spacetime . This allows us to fabricate interface between type I and type II Weyl semimetals , which is […]

Symmetry, locality and long-range interactions in atomistic machine learning ================================================= Machine learning models are proving to be extremely effective in predicting the properties of atomistic configurations of matter, circumventing the need for time consuming electronic structure calculations. The most succesful schemes achieve transferability by means of a local representation of structures, in which the problem […]
