Cooling a nanomechanical resonator by a triple quantum dot
Zeng-Zhao Li, Shi-Hua Ouyang, Chi-Hang Lam +1
We propose an approach for achieving ground-state cooling of a nanomechanical resonator (NAMR) capacitively coupled to a triple quantum dot (TQD). This TQD is an electronic analog…
Probing the quantum behaviors of a nanomechanical resonator coupled to a double quantum dot
Zeng-Zhao Li, Shi-Hua Ouyang, Chi-Hang Lam +1
We propose a current correlation spectrum approach to probe the quantum behaviors of a nanome-chanical resonator (NAMR). The NAMR is coupled to a double quantum dot (DQD), which ac…
Bound states of spatial optical dark/gray solitons in nonlocal media
Shigen Ouyang, Wei Hu, Qi Guo
It is shown that three or more dark/gray solitons can form bound states in nonlocal media. More over dark/gray solitons can form bound states in several balance distances. Numerica…
Cooling a mechanical resonator by quantum interference in a triple quantum dot
Shi-Hua Ouyang, Chi-Hang Lam, J. Q. You
We propose an approach to cool a mechanical resonator (MR) via quantum interference in a triple quantum dot (TQD) capacitively coupled to the MR. The TQD connected to three electro…
Backaction of a charge detector on a double quantum dot
Shi-Hua Ouyang, Chi-Hang Lam, J. Q. You
We develop a master equation approach to study the backaction of quantum point contact (QPC) on a double quantum dot (DQD) at zero bias voltage. We reveal why electrons can pass th…
Optical vortex soliton with self-defocusing Kerr-type nonlocal nonlinearity
Shigen Ouyang, Qi Guo
We develop one numerical method to compute the optical vortex soliton with self-defocusing Kerr-type nonlocal nonlinearity. With the numerical simulation method, the propagation an…
