Experimental measurement of the intrinsic excitonic wavefunction
Michael K. L. Man, Julien Madéo, Chakradhar Sahoo +15
An exciton, a two-body composite quasiparticle formed of an electron and hole, is a fundamental optical excitation in condensed-matter systems. Since its discovery nearly a century…
Relativistic Drude Response of Photoexcited Dirac Quasiparticles in Graphene
K. M. Dani, J. Lee, R. Sharma +7
Graphene, a monolayer of carbon atoms arranged in a hexagonal pattern, provides a unique two-dimensional (2D) system exhibiting exotic phenomena such as quantum Hall effects, massl…
Observation of inter-Landau-level quantum coherence in semiconductor quantum wells
K. M. Dani, I. A. Cotoros, J. Wang +4
Using three-pulse four-wave-mixing femtosecond spectroscopy, we excite a non-radiative coherence between the discrete Landau levels of an undoped quantum well and study its dynamic…
Nonlinear Optical studies of the Transient Coherence in the Quantum Hall System
K. M. Dani, E. G. Kavousanaki, J. Tignon +2
We review recent investigations of the femtosecond non-linear optical response of the two-dimensional electron gas (2DEG) in a strong magnetic field. We probe the Quantum Hall (QH)…
Ultrafast dynamics of coherences in the quantum Hall system
K. M. Dani, J. Tignon, M. Breit +3
Using three-pulse four-wave-mixing optical spectroscopy, we study the ultrafast dynamics of the quantum Hall system. We observe striking differences as compared to an undoped syste…
