Superradiance Emission and Its Thermal Decoherence in Lead Halide Perovskites Superlattices
Advanced Optical Materials, 2023 Self‐assembled nanocrystals (NCs) into superlattices (SLs) are alternative materials to polycrystalline films and single crystals, which can behave very differently from their constituents, especially when they interact coherently with each other.

Triggered Superradiance and Spin Inversion Storage in a Hybrid Quantum System. [PDF]
Physical Review Letters, 2023 We study the superradiant emission of an inverted spin ensemble strongly coupled to a superconducting cavity. After fast inversion, we detune the spins from the cavity and store the inversion for tens of milliseconds, during which the remaining ...

Spin superradiance versus atomic superradiance [PDF]
Laser Physics Letters, 2005 A comparative analysis is given of spin superradiance and atomic superradiance. Their similarities and distinctions are emphasized. It is shown that, despite a close analogy, these phenomena are fundamentally different. In atomic systems, superradiance is a self-organized process, in which both the initial cause, being spontaneous emission, as well as ...

Superradiance and stability of the regularized 4D charged Einstein-Gauss-Bonnet black hole
Journal of High Energy Physics, 2020 We investigated the superradiance and stability of the regularized 4D charged Einstein-Gauss-Bonnet black hole which is recently inspired by Glavan and Lin [Phys. Rev. Lett. 124, 081301 (2020)]. We found that the positive Gauss-Bonnet coupling constant α

Stepping up superradiance constraints on axions [PDF]
Physical Review DLight feebly-coupled bosonic particles can efficiently extract the rotational energy of rapidly spinning black holes on subastrophysical timescales via a phenomenon known as black hole superradiance.

Black hole superradiance of self-interacting scalar fields [PDF]
Physical Review D, 2020 Black hole superradiance is a powerful probe of light, weakly-coupled hidden sector particles. Many candidate particles, such as axions, generically have self-interactions that can influence the evolution of the superradiant instability.

Superradiance of charged black holes embedded in dark matter halos [PDF]
Physical Review DAstrophysical environments are ubiquitous in the Universe; from accretion disks around black holes to galactic dark matter halos, distributions of astrophysical material veil the vast majority of Cosmos.

Many-Body Superradiance and Dynamical Mirror Symmetry Breaking in Waveguide QED. [PDF]
Physical Review Letters, 2022 The many-body decay of extended collections of two-level systems remains an open problem. Here, we investigate whether an array of emitters coupled to a one-dimensional bath undergoes Dicke superradiance.

Magnonic superradiant phase transition [PDF]
Communications Physics, 2022 AbstractIn the superradiant phase transition (SRPT), coherent light and matter fields are expected to appear spontaneously in a coupled light–matter system in thermal equilibrium. However, such an equilibrium SRPT is forbidden in the case of charge-based light–matter coupling, known as no-go theorems.
