Influences of sinusoidal density modulation on stimulated Raman scattering in inhomogeneous plasmas

Autor: Chen, Y., Zheng, C. Y., Liu, Z. J., Cao, L. H., Feng, Q. S., Chen, Y. G., Huang, Z. M., Xiao, C. Z.

The influence of sinusoidal density modulation on the stimulated Raman scattering (SRS) reflectivity in inhomogeneous plasmas is studied by three-wave coupling equations, fully kinetic Vlasov simulations and particle in cell (PIC) simulations. Throug

Autor: Zhou, W., Li, B., Xu, C. Q., van Delft, M. R., Chen, Y. G., Fan, X. C., Qian, B., Hussey, N. E., Xu, Xiaofeng

Publikováno v: Adv. Electron. Mater. 5, 1900250 (2019)

Weyl semimetals, characterized by nodal points in the bulk and Fermi arc states on the surface, have recently attracted extensive attention due to the potential application on low energy consumption electronic materials. In this report, the thermodyn

Qcompiler: quantum compilation with CSD method

Autor: Chen, Y. G., Wang, J. B.

In this paper, we present a general quantum computation compiler, which maps any given quantum algorithm to a quantum circuit consisting a sequential set of elementary quantum logic gates based on recursive cosine-sine decomposition. The resulting qu

Local spin polarisation of electrons in Rashba semiconductor nanowires: effects of the bound state

Autor: Xiao, X. B., Li, F., Chen, Y. G., Liu, N. H.

Publikováno v: Eur. Phys. J. B 85, 112 (2012)

The local spin polarisation (LSP) of electrons in two typical semiconductor nanowires under the modulation of Rashba spin-orbit interaction (SOI) is investigated theoretically. The influence of both the SOI- and structure-induced bound states on the

Bosonization study of quantum phase transitions in the one-dimensional asymmetric Hubbard model

Autor: Wang, Z. G., Chen, Y. G., Gu, S. J.

Publikováno v: Z. G. Wang, Y. G. Chen, and S. J. Gu, Phys. Rev. B 75, 165111 (2007)

The quantum phase transitions in the one-dimensional asymmetric Hubbard model are investigated with the bosonization approach. The conditions for the phase transition from density wave to phase separation, the correlation functions and their exponent
