Optical spectroscopy of composite fermion edge states in the fractional quantum Hall effect
Maria Sebastian, Ashutosh Singh, Alexey Belyanin
We show that edge states in fractional quantum Hall effect samples can be selectively probed and excited with sub-terahertz optical spectroscopy. Using the composite fermion (CF) m…
Valley resolved optical spectroscopy and coherent excitation of quantum Hall edge states in graphene
Ashutosh Singh, Maria Sebastian, Mikhail Tokman +1
We show that chiral edge states in graphene under Quantum Hall effect conditions can be selectively probed and excited by terahertz or infrared radiation with single-quasiparticle…
Polarized Superradiance from CsPbBr3 Quantum Dot Superlattice with Controlled Inter-dot Electronic Coupling
Lanyin Luo, Xueting Tang, Junhee Park +8
Cooperative emission of photons from an ensemble of quantum dots (QDs) as superradiance can arise from the electronically coupled QDs with a coherent emitting excited state. This c…
Coherent optical control of quantum Hall edge states
Ashutosh Singh, Maria Sebastian, Mikhail Tokman +1
Current carrying chiral edge states in quantum Hall systems have fascinating properties that are usually studied by electron spectroscopy and interferometry. Here we demonstrate th…
Quantum gates utilizing dark and bright states in open dissipative cavity QED
Mikhail Tokman, Jitendra Verma, Alexey Belyanin
We present a general formalism and specific implementation of quantum gates based on interaction of single photons with open dissipative nanocavities containing ensembles of quantu…
