Equivariant Poisson 2-Algebra Bundles over Configuration Spaces
Hai Châu Nguyên
We study equivariant vector bundles over configuration spaces with diagonals included, viewed as orbifold quotients by permutation groups. Working in the equiv…

Ultradecoherence model of the measurement process
Hai-Chau Nguyen
It is proposed that measurement devices can be modelled to have an open decoherence dynamics that is faster than any other relevant timescale, which is referred to as the ultradeco…

Hybridization of Non-Hermitian Topological Interface Modes
Yuhao Wang, Hai-Chau Nguyen, Zhiyi Yuan +5
We propose and experimentally demonstrate the hybridization of radiating topological interface states, analogous to Jackiw-Rebbi states but in gain media with radiation fields. Thi…
