Periodic cavity state revivals from atomic frequency combs

Matthias Zens, Dmitry O. Krimer, Himadri S. Dhar +1

Spin ensembles with a comb-shaped spectrum have shown exciting properties as efficient quantum memories. Here, we present a rigorous theoretical study of such atomic frequency comb…

Quest for Vortices in Photon Condensates

Himadri S. Dhar, Zai Zuo, João D. Rodrigues +2

We predict that a photon condensate inside a dye-filled microcavity forms long-lived spatial structures that resemble vortices when incoherently excited by a focused pump orbiting…

Transport and localization of light inside a dye-filled microcavity

Himadri S. Dhar, João D. Rodrigues, Benjamin T. Walker +3

The driven-dissipative nature of light-matter interaction inside a multimode, dye-filled microcavity makes it an ideal system to study nonequilibrium phenomena, such as transport.…

Non-critical slowing down of photonic condensation

Benjamin T. Walker, Henry J. Hesten, Himadri S. Dhar +2

We investigate the response of a photonic gas interacting with a reservoir of pumped dye-molecules to quenches in the pump power. In addition to the expected dramatic critical slow…

Effect of long-range interactions on multipartite entanglement in Heisenberg chains

Sudipto Singha Roy, Himadri Shekhar Dhar

It is well known that the notions of spatial locality are often lost in quantum systems with long-range interactions, as exhibited by the emergence of phases with exotic long-range…

Tensor-network approach to compute genuine multisite entanglement in infinite quantum spin chains

Sudipto Singha Roy, Himadri Shekhar Dhar, Aditi Sen De +1

We devise a method based on the tensor-network formalism to calculate genuine multisite entanglement in ground states of infinite spin chains containing spin-1/2 or spin-1 quantum…
