Diagrammatic Quantum Monte Carlo for Two-Body Problems: Applied to Excitons
Accurate numerical solution exciton solid monte carlo simulation catamaran green function feynman electron hole
2014/12/22
We present a novel method for the precise numeric solution of the irreducible two-body problem and apply it to excitons in solids. The approach is based on the Monte Carlo simulation of the two-body G...
Observation of Superfluorescence from a Spontaneous Coherence of Excitons in ZnTe Crystal: Evidence for Bose-Einstein Condensation of Excitons?
Superfluorescence Spontaneous Coherence Excitons ZnTe Crystal Bose-Einstein Condensation
2011/8/11
Abstract: Superfluorescence (SF) is the emission from a dense coherent system in population inversion, formed from an initially incoherent ensemble. This is characterised by an induction time (t_D) fo...
Impurity-trapped excitons and electron traps in CaF$_2$:Yb$^{2+}$ and SrF$_2$:Yb$^{2+}$ probed by transient photoluminescence enhancement

2011/8/18
Abstract: CaF$_2$:Yb$^{2+}$ and SrF$_2$:Yb$^{2+}$ crystals have been investigated by a two-color UV + IR transient photoluminescence enhancement technique. The enhancement gives information about both...
Transient photoluminescence enhancement as a probe of the structure of impurity-trapped excitons in CaF$_2$:Yb$^{2+}$

Abstract: We demonstrate a direct measurement of the energy levels of impurity-trapped excitons in CaF$_2$:Yb$^{2+}$. The radically different radiative decay rates of the lowest exciton state and high...
Effects of variable anisotropic-strain on the emission of neutral excitons confined in epitaxial quantum dots
Effects of variable anisotropic-strain neutral excitons epitaxial quantum dots
2010/11/22
We study the e ect of elastic anisotropic biaxial strain on the light emitted by neutral excitons confined in di erent kinds of semiconductor quantum dots (QDs). We find that the light polarization ro...
Excitons in Molecular Aggregates with Lévy Disorder: Anomalous Localization and Exchange Broadening of Optical Spectra
Excitons in Molecular Aggregates Lévy Disorder Anomalous Localization Exchange Broadening of Optical Spectra
2010/10/21
We predict the existence of exchange broadening of optical lineshapes in disordered molecular
aggregates and a nonuniversal disorder scaling of the localization characteristics of the collective elec...

Binding Energies of Excitons in Symmetric and Asymmetric Coupled Double-Quantum Well Structures in a Magnetic Field
Binding Energies Double-Quantum Well Structures Magnetic Field
2010/4/16
The binding energy of excitons in the symmetric and asymmetric coupled double GaAs/Ga1-xAlxAs quantum wells is calculated by using variational approach. Results have been obtained as a function of the...
