Topological bands in one-dimensional periodic potentials

Yi Zheng, Shi-Jie Yang

We study the properties of the quantum states in the one-dimensional system with a shifted periodic potential in both the discrete model and the continuous model. With open boundar…

Negative differential conductance and super-Poissonian shot noise in single-molecule magnet junctions

Hai-Bin Xue, Jiu-Qing Liang, Wu-Ming Liu

Molecular spintroinic device based on a single-molecule magnet is one of the ultimate goals of semiconductor nanofabrication technologies. It is thus necessary to understand the el…

Nonlinear optical response induced by non-Abelian Berry curvature in time-reversal-invariant insulators

Fan Yang, Ren-Bao Liu

We propose a general framework of nonlinear optics induced by non-Abelian Berry curvature in time-reversal-invariant (TRI) insulators. We find that the third-order response of a TR…

A NOT operation on Majorana qubits with mobilizable solitons in an extended Su-Schrieffer-Heeger model

Ye Xiong, Peiqing Tong

Coupling Majorana qubits with other qubits is an absolute essential in storing, manipulating and transferring informations for topological quantum computing. We theoretically propo…

Single-spin manipulation in a double quantum dot in the field of a micromagnet

Stefano Chesi, Ying-Dan Wang, Jun Yoneda +3

The manipulation of single spins in double quantum dots by making use of the exchange interaction and a highly inhomogeneous magnetic field was discussed in [W. A. Coish and D. Los…

Faraday rotation echo spectroscopy and detection of quantum fluctuations

Shao-Wen Chen, Ren-Bao Liu

Central spin decoherence is useful for detecting many-body physics in environments and moreover, the spin echo control can remove the effects of static thermal fluctuations so that…

Diabolical points in multi-scatterer optomechanical systems

Stefano Chesi, Ying-Dan Wang, Jason Twamley

Diabolical points, which originate from parameter-dependent accidental degeneracies of a system's energy levels, have played a fundamental role in the discovery of the Berry phase…
