Superradiance instabilities of charged black holes in Einstein-Maxwell-scalar theory [PDF]
Journal of High Energy Physics, 2023 We study time evolutions of charged scalar perturbations on the background of a charged hairy black hole, in which the perturbations can be governed by a double-peak effective potential.

Scalar fields around a rotating loop quantum gravity black hole: waveform, quasi-normal modes and superradiance [PDF]
Classical and quantum gravity, 2023 The rotating loop quantum gravity black hole is a newly proposed non-singular black hole, which eliminates spacetime singularities when a regularization parameter is introduced through loop quantum corrections.

Chirality dependent photon transport and helical superradiance [PDF]
Physical Review Research, 2023 Chirality, or handedness, is a geometrical property denoting a lack of mirror symmetry. Chirality is ubiquitous in nature and is associated with the nonreciprocal interactions observed in complex systems ranging from biomolecules to topological materials.

Signatures of Superradiance as a Witness to Multipartite Entanglement. [PDF]
Physical Review Letters, 2023 Generation and detection of entanglement is at the forefront of most quantum information technologies. There is a plethora of techniques that reveal entanglement on the basis of only partial information about the underlying quantum state, including ...

Superradiance in Quantum Vacuum
Quantum Reports, 2021 A new process associated with the nonlinear optical properties of the electromagnetic quantum vacuum is described. It corresponds to the superradiant emission of photons, resulting from the interaction of an intense laser pulse with frequency ω0 with a ...

Physical Review Letters, 2015 We show that the timed Dicke states of a collection of three-level atoms can form a tight-binding lattice in momentum space. This lattice, coined the superradiance lattice (SL), can be constructed based on electromagnetically induced transparency (EIT). For a one-dimensional SL, we need the coupling field of the EIT system to be a standing wave.

Superradiant Quantum Heat Engine [PDF]
Scientific Reports, 2015 AbstractQuantum physics revolutionized classical disciplines of mechanics, statistical physics and electrodynamics. One branch of scientific knowledge however seems untouched: thermodynamics. Major motivation behind thermodynamics is to develop efficient heat engines.

Explaining Recurring Maser Flares in the ISM Through Large-scale Entangled Quantum Mechanical States [PDF]
, 2017 We apply Dicke's theory of superradiance introduced in 1954 to the methanol 6.7 GHz and water 22 GHz spectral lines, often detected in molecular clouds as signposts for the early stages of the star formation process.

Charge (in)stability and superradiance of Topological Stars [PDF]
Journal of High Energy PhysicsWe study linear massive scalar charged perturbations of Topological Stars in the fuzzball and in the black hole (Black String) regimes. The objects that naturally couple to the electric 3-form field strength of these solutions are charged strings, wound ...
