Comparative Study of Indicators of Chaos in the Closed and Open Dicke Model
Prasad Pawar, Arpan Bhattacharyya, B. Prasanna Venkatesh
The Dicke model, renowned for its superradiant quantum phase transition, also exhibits a transition from regular to chaotic dynamics. In this work, we provide a systematic, compara…

Measurement Induced Subradiance
Ipsita Bar, Aditi Thakar, B. Prasanna Venkatesh
Preparing subradiant steady states of collectively emitting quantum two-level emitters (TLEs) is hindered by their dark, weakly interacting nature. Existing approaches rely on patt…

Collective Dissipation of Oscillator Dipoles Strongly Coupled to 1-D Electromagnetic Reservoirs
Subhasish Guha, Ipsita Bar, Bijay Kumar Agarwalla +1
We study the collective dissipative dynamics of dipoles modeled as harmonic oscillators coupled to 1-D electromagnetic reservoirs. The bosonic nature of the dipole oscillators as w…
