Stimulated coherent spontaneous emission in an FEL with 'quiet' bunches
shot noise reduction controlled microbunching instability laser heater
2012/5/31
For a planar FEL configuration we study stimulated coherent spontaneous emission driven by a gradient of the bunch current in the presence of different levels of noise in bunches. To perform a vast am...
Metallo-dielectric hybrid antennas for ultrastrong enhancement of spontaneous emission
Metallo-dielectric hybrid antennas ultrastrong enhancement of spontaneous emission Optics
2012/5/29
We devise new optical antennas that reduce the excited-state radiative lifetimes of emitters to the order of 100 femtoseconds while maintaining quantum efficiencies of about 80% at a broadband operati...
Inhibited spontaneous emission of quantum dots observed in a 3D photonic band gap
3D photonic band gap spontaneous emission
2011/8/31
We present time-resolved emission experiments of semiconductor quantum dots in silicon 3D inverse-woodpile photonic band gap crystals. A systematic study is made of crystals with a range of pore radii...
Spontaneous emission spectrum of a V-type three-level atom in a Fabry–Perot cavity containing left-handed materials
Spontaneous emission spectrum V-type three-level atom Fabry–Perot cavity left-handed materials
2014/5/28
The spontaneous emission of a V-type Zeeman atom in a Fabry–Perot cavity containing left-handed materials(LHMs) is investigated. Because of the strong indirect quantum interference induced by the refo...
Bosonic enhancement of spontaneous emission near an interface
Bosonic enhancement spontaneous emission
2010/11/24
We show how the spontaneous emission rate of an excited two-level atom placed in a trapped Bose-Einstein condensate of ground-state atoms is enhanced by bosonic stimulation. This stimulation depends o...
A qubit strongly-coupled to a resonant cavity: asymmetry of the spontaneous emission spectrum beyond the rotating wave approximation
spontaneous emission spectrum vacuum Rabi splitting qubit strongly-coupled to a cavity
2010/10/20
We investigate the spontaneous emission spectrum of a qubit in a lossy resonant cavity. We
use neither the rotating-wave approximation nor the Markov approximation. The qubit-cavity
coupling strengt...
Non-equilibrium dynamics of bosonic atoms in optical lattices: Decoherence of many-body states due to spontaneous emission
Non-equilibrium dynamics of bosonic atoms optical lattices Decoherence of many-body states spontaneous emission
2010/10/21
We analyze in detail the heating of bosonic atoms in an optical lattice due to incoherent scattering of light from the lasers forming the lattice. Because atoms scattered into higher bands do not ther...
Quantum interference due to energy shifts and its effect on spontaneous emission
Quantum interference energy shifts spontaneous emission
2014/5/28
We study the quantum interference in spontaneous emission with the inclusion of counterrotating terms and energy shifts. The energy shifts come from the emission and then reabsorption of virtual photo...
