Fast phonon dynamics of a nanomechanical oscillator due to cooperative effects
Victor Ceban, Paolo Longo, Mihai A. Macovei
We investigate the coupled-system dynamics of two-level quantum dots placed on a vibrating nanomechanical resonator. The ensemble of quantum dots exhibits superradiance features wh…
Experimental verification of orbital engineering at the atomic scale: charge transfer and symmetry breaking in nickelate heterostructures
Patrick J. Phillips, Paolo Longo, Alexandru B. Georgescu +7
Epitaxial strain, layer confinement and inversion symmetry breaking have emerged as powerful new approaches to control the electronic and atomic-scale structural properties in comp…
Tailoring superradiance to design artificial quantum systems
Paolo Longo, Christoph H. Keitel, Jörg Evers
Cooperative phenomena arising due to the coupling of individual atoms via the radiation field are a cornerstone of modern quantum and optical physics. Recent experiments on x-ray q…
Probing few-excitation eigenstates of interacting atoms on a lattice by observing their collective light emission in the far field
P. Longo, J. Evers
The collective emission from a one-dimensional chain of interacting two-level atoms coupled to a common electromagnetic reservoir is investigated. We derive the system's dissipativ…
Far-Field Signatures of a Two-Body Bound State in Collective Emission from Interacting Two-Level Atoms on a Lattice
Paolo Longo, Jörg Evers
The collective emission from a one-dimensional chain of interacting two-level atoms is investigated. We calculate the light scattered by dissipative few-excitation eigenstates in t…
Few-photon transport in low-dimensional systems: Interaction-induced radiation trapping
Paolo Longo, Peter Schmitteckert, Kurt Busch
We present a detailed analysis of the dynamics of photon transport in waveguiding systems in the presence of a two-level system. In these systems, quantum interference effects gene…
Emission of gravitational waves from binary systems in the galactic center and diffraction by star clusters
P. Longo, G. Congedo, A. Nucita +2
Binary systems of compact objects are strong emitters of gravitational waves whose amplitude depends on the binary orbital parameters as the component mass, the orbital semi-major…
Gravitational wave scintillation by a stellar cluster
G. Congedo, F. De Paolis, P. Longo +2
The diffraction effects on gravitational waves propagating through a stellar cluster are analyzed in the relevant approximation of Fresnel diffraction limit. We find that a gravita…
