Terahertz wave generation from hyper-Raman lines in two-level quantum systems driven by two-color lasers
Wei Zhang, Shi-Fang Guo, Su-Qing Duan +1
Based on spatial-temporal symmetry breaking mechanism, we propose a novel scheme for terahertz (THz) wave generation from hyper-Raman lines associated with the 0th harmonic (a part…
Tailoring photon emission patterns in nanostructures
Shi-Fang Guo, Suqing Duan, Yan Xie +2
We investigate the photon emission in coupled quantum dots based on symmetry considerations. With the help of a new theorem we proved, we reveal the origin of the various emission…
Critical parameters for the one-dimensional systems with long-range correlated disorder
Yi Zhao, Suqing Duan, Wei Zhang
We study the metal-insulator transition in a tight-binding one-dimensional (1D) model with long-range correlated disorder. In the case of diagonal disorder with site energy within…
Quantum blockade and loop current induced by a single lattice defect in graphene nanoribbons
Jie-Yun Yan, Ping Zhang, Bo Sun +4
We investigate theoretically the electronic transport properties in narrow graphene ribbons with an adatom-induced defect. It is found that the lowest conductance step of a metalli…
Quasienergy spectra of a charged particle in planar honeycomb lattices
Wei Zhang, Ping Zhang, Suqing Duan +1
The low energy spectrum of a particle in planar honeycomb lattices is conical, which leads to the unusual electronic properties of graphene. In this letter we calculate the quasien…
Photon-assistant Fano resonance in coupled multiple quantum dots
Wanyuan Xie, Hui Pan, Weidong Chu +2
Based on calculations of the electronic structure of coupled multiple quantum dots, we study systemically the transport properties of the system driven by an ac electric field. We…
