Machine‐learning‐assisted photonic device development: a multiscale approach from theory to characterization

open access: yesNanophotonics, Volume 14, Issue 23, Page 3761-3793, 02 November 2025.
Abstract Photonic device development (PDD) has achieved remarkable success in designing and implementing new devices for controlling light across various wavelengths, scales, and applications, including telecommunications, imaging, sensing, and quantum information processing.

On continuity of measurable group representations and homomorphisms [PDF]

open access: yes, 2015
Let G be a locally compact group, and let U be its unitary representation on a Hilbert space H. Endow the space L(H) of linear bounded operators on H with weak operator topology. We prove that if U is a measurable map from G to L(H) then it is continuous.

Commutator criteria for strong mixing II. More general and simpler

open access: yes, 2015
8 pagesWe present a new criterion, based on commutator methods, for the strong mixing property of unitary representations of topological groups equipped with a proper length function.

Trace class groups

open access: yes, 2016
A representation $\pi$ of a locally compact group $G$ is called \e{trace class}, if for every test function $f$ the induced operator $\pi(f)$ is a trace class operator. The group $G$ is called \e{trace class}, if every $\pi\in G$ is trace class.
