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…
