Dual-band valley-protected topological edge states in graphene-like phononic crystals with waveguide
Since valley was introduced into phononic crystals, it has promoted far-reaching developments in topologically protected acoustic transmission. However, in the novel research field of valley-Hall phononic topo...

One-step quantum phase gate in the ultrastrong coupling regime of circuit QED
In a previous publication (Phys Rev Lett 108: 120501, 2012), Romero et al. proposed an ultrastrong coupling circuit QED system that can implement a two-qubit quantum phase gate with four controlling pulses. Based...

Open AccessInvestigation of mechanism: spoof SPPs on periodically textured metal surface with pyramidal grooves
In microwave and terahertz frequency band, a textured metal surface can support spoof surface plasmon polaritons (SSPPs). In this paper, we explore a SSPPs waveguide composed of a metal block with pyramidal gr...

Super-resolution imaging of a single metal layer: high loss but superior resolution
In this work, we re-analyze the influence of the loss on the super-resolution imaging of a single metal layer superlens system and reveal its positive role of the imaging. The analysis is based on the surface ...

Open AccessA silicon nanowire photodetector using Au plasmonic nanoantennas
We suggest a silicon nanowire (SiNW) photodetector side-contacted with hemispherical Au nanoantennas (NAs) that can remarkably amplify the intensity of the near-infrared optical field. The plasmonic NA suppres...

The formation of different structures in the interaction between a single femtosecond laser pulse and a thin Au film
The interactions between femtosecond (fs) laser pulses and a thin Au film deposited on a silica glass substrate were systematically investigated based on experimental data. Different structures, including micr...

Multi-layer coating of SiO2 nanoparticles to enhance light absorption by Si solar cells
We found that multi-layer coating of a Si substrate with SiO2 dielectric nanoparticles (NPs) was an effective method to suppress light reflection by silicon solar cells. To suppress light reflection, two conditio...
