Spin correlations in nonlinear optical response: Light-induced Kondo effect
T. V. Shahbazyan, I. E. Perakis, M. E. Raikh
We study the role of spin correlations in nonlinear absorption due to optical transitions from a deep impurity level to states above a Fermi sea. We demonstrate that the Hubbard re…
Electronic Dephasing in the Quantum Hall Regime
N. A. Fromer, C. Schüller, D. S. Chemla +4
By means of degenerate four-wave mixing (FWM), we investigate the quantum coherence of electron-hole pairs in the presence of a two-dimensional electron gas in modulation-doped GaA…
Coherent Ultrafast Optical Dynamics of the Fermi Edge Singularity
N. Primozich, T. V. Shahbazyan, I. E. Perakis +1
We develop a non-equilibrium many-body theory of the coherent femtosecond nonlinear optical response of the Fermi edge singularity. We study the role of the dynamical Fermi sea res…
Femtosecond Coherent Dynamics of the Fermi Edge Singularity and Exciton Hybrid
T. V. Shahbazyan, N. Primozich, I. E. Perakis +1
We study theoretically the coherent nonlinear optical response of doped semiconductors with partially occupied subbands. When the Fermi energy of an occupied subband approaches the…
Mesoscopic Cooperative Emission From a Disordered System
T. V. Shahbazyan, M. E. Raikh, Z. V. Vardeny
We study theoretically the cooperative light emission from a system of classical oscillators confined within a volume with spatial scale, , much smaller than the radiat…
Canonical Transformation Approach to the Ultrafast Non-linear Optical Dynamics of Semiconductors
I. E. Perakis, T. V. Shahbazyan
We develop a theory describing the effects of many-particle Coulomb correlations on the coherent ultrafast nonlinear optical response of semiconductors and metals. Our approach is…
