Anharmonicity in GaTe layered crystals

Lattice Vibration of Layered GaTe Single Crystals

The effect of interlayer interaction on in-layer structure of laminar GaTe crystals was studied according to the lattice vibration using micro-Raman analysis. The results were also confirmed by the first principle calculations. Accordingly, the relationship between lattice vibration and crystal structure was established. Ten peaks were observed in the micro-Raman spectra from 100 cm−1 to 300 cm...

Light Tunneling in Multi-Layered Plasmonic Crystals

In this work, we are demonstrating resonant light transmission through hybrid multi-layered plasmonic crystals, which are formed by a coupled nanohole and a nanoparticle array. This structures are shown to provide the conventional extraordinary optical transmission (EOT) peaks and also a newly found cavity-based mode is introduced with an emphasis to its high sensing capabilities. Plasmon hybri...

Phonon heat conduction in layered anisotropic crystals

The thermal properties of anisotropic crystals are of both fundamental and practical interest, but transport phenomena in anisotropic materials such as graphite remain poorly understood because solutions of the Boltzmann equation often assume isotropy. Here, we extend an analytic solution of the transient, frequencydependent Boltzmann equation to highly anisotropic solids and examine its predic...

Two-qubit gate operations in superconducting circuits with strong coupling and weak anharmonicity

We theoretically study the implementation of two-qubit gates in a system of two coupled superconducting qubits. In particular, we analyze two-qubit gate operations under the condition that the coupling strength is comparable with or even larger than the anharmonicity of the qubits. By numerically solving the time-dependent Schrödinger equation under the assumption of negligible decoherence, we ...
