Dynamics of the fractional quantum Hall edge probed by stroboscope measurements of trions
Akinori Kamiyama, Masahiro Matsuura, John N. Moore +3
By using observations from pump-probe stroboscopic confocal microscopy and spectroscopy, we demonstrate the dynamics of trions and the fractional quantum Hall edge on the order of…
Thermal Transport Imaging in the Quantum Hall Edge Channel
J. N. Moore, A. Kamiyama, T. Mano +1
Research focused on heat transport in the quantum Hall (QH) edge channel has successfully addressed fundamental theoretical questions surrounding the QH physics. However, the pictu…
Spin helices in GaAs quantum wells: Interplay of electron density, spin diffusion, and spin lifetime
S. Anghel, A. V. Poshakinskiy, K. Schiller +4
To establish a correlation between the spin diffusion, the spin lifetime, and the electron density, we study, employing time-resolved magneto-optical Kerr effect microscopy, the sp…
Real-time and -space visualization of excitations of the ν= 1/3 fractional quantum Hall edge
Akinori Kamiyama, Masahiro Matsuura, John N. Moore +3
We present scanning optical stroboscopic confocal microscopy and spectroscopy measurements wherein three degrees of freedom, namely energy, real-space, and real-time, are resolvabl…
Single photon emission from droplet epitaxial quantum dots in the standard telecom window around a wavelength of 1.55 m
N. Ha, T. Mano, S. Dubos +3
We study the luminescence dynamics of telecom wavelength InAs quantum dots grown on InP(111)A by droplet epitaxy. The use of the ternary alloy InAlGaAs as a barrier material leads…
Current-injection quantum-entangled-pair emitter using droplet epitaxial quantum dots on GaAs(111)A
Neul Ha, Takaaki Mano, Takashi Kuroda +2
A source of single photons and quantum entangled photon pairs is a key element in quantum information networks. Here, we demonstrate the electrically driven generation of quantum e…
