SPT 2-Channel Kondo Model in the Structure of Normal Metal/Quantum Dot/DIII-class Topological Superconductor
Zhen Gao, Wei-Jiang Gong
We investigate the Kondo effect in a structure which is constructed by embedding one quantum dot between a normal metal and a \emph{DIII}-class topological superconductor supportin…
Deep-subwavelength magnetic-coupling-dominant stereometamaterials
Zhen Gao, Fei Gao, Youming Zhang +1
Here, we experimentally demonstrate that a stack of metallic spiral structures (MSSs) can have dominant magnetic coupling in both of its two configurations. This allows magnetic-co…
Complementary magnetic localized surface plasmons
Zhen Gao, Fei Gao, Youming Zhang +1
Magnetic localized surface plasmons (LSPs) supported on metallic structures corrugated by very long and curved grooves have been recently proposed and demonstrated on an extremely…
Vertical Transport of Subwavelength Localized Surface Electromagnetic Modes
Fei Gao, Zhen Gao, Youming Zhang +3
Transport of subwavelength electromagnetic (EM) energy has been achieved through near-field coupling of highly confined surface EM modes supported by plasmonic nanoparticles, in a…
Majorana modes in a triple-terminal Josephson junction with embedded parallel-coupled double quantum dots
Guang-Yu Yi, Xiao-Qi Wang, Zhen Gao +2
We investigate the Josephson effect in one triple-terminal junction with embedded parallel-coupled double quantum dots. It is found that the inter-superconductor supercurrent has o…
Dynamical Mechanism of Two-Dimensional Plasmon Launching by Swift Electrons
Xiao Lin, Xihang Shi, Fei Gao +8
Launching of surface plasmons by swift electrons has long been utilized in electron-energy-loss spectroscopy (EELS) to investigate plasmonic properties of ultrathin, or two-dimensi…
Josephson effects in the junction formed by \emph{DIII}-class topological and -wave superconductors with an embedded quantum dot
Zhen Gao, Wan-Fei Shan, Wei-Jiang Gong
We investigate the Josephson effects in the junction formed by \emph{DIII}-class topological and -wave superconductors, by embedding a quantum dot in the junction. Three dot-sup…
Probing topological protection using a designer surface plasmon structure
Fei Gao, Zhen Gao, Xihang Shi +9
Topological photonic states, inspired by robust chiral edge states in topological insulators, have recently been demonstrated in a few photonic systems, including an array of coupl…
Influence of an embedded quantum dot on the Josephson effect in the topological superconducting junction with Majorana doublets
Wei-Jiang Gong, Zhen Gao, Wan-Fei Shan +1
One Majorana doublet can be realized at each end of the time-reversal-invariant Majorana nanowires. We investigate the Josephson effect in the Majorana-doublet-presented junction m…
