Slow propagation of 2 GHz acoustical waves in a suspended GaAs on insulator phononic waveguide
Giuseppe Modica, Rui Zhu, Robert Horvath +3
Optoelectronic oscillators have dominated the scene of microwave oscillators in the last few years thanks to their great performances regarding frequency stability and phase noise.…
Unconventional topological Hall effect in high-topological-number skyrmion crystals
Rui Zhu, Weinan Liu
Skyrmions with the topological number equal an integer larger than 1 are called high-topological-number skyrmions or high- skyrmions. In this work, we theoretically study th…
Optomechanical Gigahertz Oscillator made of a Two Photon Absorption free piezoelectric III/V semiconductor
Inès Ghorbel, François Swiadek, Rui Zhu +8
Oscillators in the GHz frequency range are key building blocks for telecommunication, timing and positioning applications. Operating directly in the GHz and compactness while keepi…
Quantum pumping with adiabatically modulated barriers in three-band pseudospin-1 Dirac-Weyl systems
Xiaomei Chen, Rui Zhu
In this work, pumped currents of the adiabatically-driven double-barrier structure based on the pseudospin-1 Dirac-Weyl fermions are studied. As a result of the three-band dispersi…
Development in the Scattering Matrix Theory: From Spin-Orbit-Coupling Affected Shot Noise to Quantum Pumping
Rui Zhu
The review chapter starts by a pedagogical introduction to the general concept of the scattering theory: from the fundamental wave-function picture to the second-quantization langu…
AC square-wave, sawtooth-wave, and triangle-wave fields driven adiabatic quantum pumps in nanowire structures
Rui Zhu, Xiao-Kang Zhang, Xiaowen Chen
A dc current can be pumped through a nanostructure by two out-of-phase ac driving fields. In this approach, we explore the pumped current properties driven by square-wave, sawtooth…
