We discuss a class of three-band non-Abelian topological insulators in three dimensions that carry a single bulk Hopf index protected by spatiotemporal ($\mathcal{PT}$) inversion symmetry. These phases may also host subdimensional topological invaria

Covariance Assisted Multivariate Penalized Additive Regression (CoMPAdRe)

Autor: Desai, Neel, Baladandayuthapani, Veerabhadran, Shinohara, Russell T., Morris, Jeffrey S.

We propose a new method for the simultaneous selection and estimation of multivariate sparse additive models with correlated errors. Our method called Covariance Assisted Multivariate Penalized Additive Regression (CoMPAdRe) simultaneously selects am

Optical manifestations of topological Euler class

Autor: Jankowski, Wojciech J., Morris, Arthur S., Bouhon, Adrien, Ünal, F. Nur, Slager, Robert-Jan

We analyze quantum-geometric bounds on optical weights in topological phases with pairs of bands hosting non-trivial Euler class, a multi-gap invariant characterizing non-Abelian band topology. We show how the bounds constrain the combined optical we

Andreev reflection in Euler materials

Autor: Morris, Arthur S., Bouhon, Adrien, Slager, Robert-Jan

Publikováno v: New J. Phys. 26, 023014 (2024)

Many previous studies of Andreev reflection have demonstrated that unusual effects can occur in media which have a nontrivial bulk topology. Following this line of investigation, we study Andreev reflection in topological Euler materials by analysing

Early-Phase Local-Area Model for Pandemics Using Limited Data: A SARS-CoV-2 Application

Autor: Shi, Jiasheng, Morris, Jeffrey S., Rubin, David M., Huang, Jing

The emergence of novel infectious agents presents challenges to statistical models of disease transmission. These challenges arise from limited, poor-quality data and an incomplete understanding of the agent. Moreover, outbreaks manifest differently
