Hole spin splitting in a Ge quantum dot with finite barriers
Jiawei Wang, Xuedong Hu, Herbert F Fotso
We study the low-energy spectrum of a single hole confined in a planar Ge quantum dot (QD) within the effective-mass formalism. The QD is sandwiched between two GeSi barriers of fi…

Super-Poissonian Squeezed Light in the Deep Strong Regime of the Quantum Rabi Model
Chon-Fai Kam, Xuedong Hu
By analytically solving the quantum Rabi model, we investigate the photonic properties of its ground eigenstate. In particular, we find that in the deep strong coupling regime, whe…
