Spontaneous emission from driven polar quantum systems
Piotr GÅadysz, Karolina SÅowik, Francesco V. Pepe
We investigate spontaneous radiative processes in a driven polar two-level system whose interaction with the laser field is dominated by broken inversion symmetry rather than by th…
Quantum Walk on a Line with Absorbing Boundaries
Ammara Ammara, Václav PotoÄek, Václav Potoček +3
Absorption of two-state coined quantum walks on a finite line with two sinks located at and is investigated. Elaborating on the results of Konno et al., J. Phys. A: Math.…
Superradiant decay in non-Markovian Waveguide Quantum Electrodynamics
Rosa Lucia Capurso, Giuseppe Calajó, Simone Montangero +5
An array of initially excited emitters coupled to a one-dimensional waveguide exhibits superradiant decay under the Born-Markov approximation, manifested as a coherent burst of pho…
Non-Markovian dynamics of generation of bound states in the continuum via single-photon scattering
Giuseppe Magnifico, Maria Maffei, Domenico Pomarico +4
The excitation of bound states in the continuum (BICs) in two- or multi-qubit systems lies at the heart of entanglement generation and harnessing in Waveguide Quantum Electrodynami…
Quasi-degenerate resonant eigenstate doublets of two quantum emitters in a closed waveguide
Ammara Ammara, Paolo Facchi, Saverio Pascazio +2
The physics of systems of quantum emitters in waveguide quantum electrodynamics is significantly influenced by the relation between their spatial separation and the wavelength of t…
Condensation of vanishing photon emission rates in random atomic clouds
Viviana Viggiano, Romain Bachelard, Fabio Deelan Cunden +5
In the collective photon emission from atomic clouds both the atomic transition frequency and the decay rate are modified compared to a single isolated atom, leading to the effects…
