Nonadiabatic Wave-Packet Dynamics: Nonadiabatic Metric, Quantum Geometry, and Gravitational Analogy
Yafei Ren, M. E. Sanchez Barrero
We develop a unified theory for the nonadiabatic wave-packet dynamics of Bloch electrons subject to slowly varying spatial and temporal perturbations. Extending the conventional wa…

Global representation theory: Homological foundations
Miguel Barrero, Tobias Barthel, Luca Pol +2
A global representation is a compatible collection of representations of the outer automorphism groups of the groups belonging to some collection of finite groups . Gl…

On minimal bases in homotopical combinatorics
Katharine Adamyk, Scott Balchin, Miguel Barrero +3
We present a development in the computational suite for the study of operads for a finite group . This progress is achieved using the simple yet powerful observation…
