Quantum storage with flat bands
Carlo Danieli, Jie Liu, Rudolf A. Römer +1
The realization of robust quantum storage devices relies on the ability to generate long-lived, spatially localized quantum states. In this work, we introduce a method for the targ…
Floquet control of global symmetry in 2D arrays of quadrimer waveguides
Bo Zhu, Honghua Zhong, Jun Jia +2
Manipulating the global symmetry of a non-Hermitian composite system is a rather significative and challenging task. Here, we investigate Floquet control of global symmet…
Topological Floquet edge states in periodically curved waveguides
Bo Zhu, Honghua Zhong, Yongguan Ke +4
We study the Floquet edge states in arrays of periodically curved optical waveguides described by the modulated Su-Schrieffer-Heeger model. Beyond the bulk-edge correspondence, our…
Entanglement of Two Quantum Dots with the Flip-Flop Interaction coupled to Plasmonic Waveguide
Myong-Chol Ko, Nam-Chol Kim, Nam-Chol Ho +1
We investigate theoretically the entanglement of two quantum dots (QDs) coupled to metallic nanowaveguide in the presence of the flip-flop interaction with the analytical solutions…
Floquet control of the gain and loss in a PT-symmetric optical coupler
Yi Wu, Bo Zhu, Shufang Hu +2
Controlling the balanced gain and loss in a PT-symmetric system is a rather challenging task. Utilizing Floquet theory, we explore the constructive role of periodic modulation in c…
Plasmonic Effect on the Population Dynamics and the Optical Response in a Hybrid V-Type Three-Level Quantum Dot-Metallic Nanoparticle Nanosystem
Myong-Chol Ko, Nam-Chol Kim, Song-Il Choe +4
We investigated theoretically the exciton-plasmon coupling effects on the population dynamics and the absorption properties of a hybrid nanosystem composed of a metal nanoparticle…
