Twisted quantum affine superalgebra , invariant R-matrices and a new integrable electronic model [PDF]
, 1996 We describe the twisted affine superalgebra sl(2\2)((2)) and its quantized version U-q[sl(2\2)((2))]. We investigate the tensor product representation of the four-dimensional grade star representation for the fixed-point sub superalgebra U-q[osp(2\2 ...

Hot electron modelling of HEMTs [PDF]
7th International Workshop on Computational Electronics. Book of Abstracts. IWCE (Cat. No.00EX427), 2001 The hot‐electron two‐dimensional HEMT with recessed gate is modelled by solving the Poisson, current continuity and energy transport equations consistently with the Schrödinger equation using a finite difference scheme. New expressions are used for the energy densities inside and outside the quantum wells.

Polariton lasing in InGaN quantum wells at room temperature
Opto-Electronic Advances, 2019 In this paper, we report the exciton polaritons in both positive and negative detuning micro cavities based on InGaN multi-quantum wells (MQWs) and the first polariton lasing in InGaN/GaN MQWs at room temperature by utilizing a 4.5λ Fabry-Perot (F-P ...

Robust and Efficient Harmonics Denoising in Large Dataset Based on Random SVD and Soft Thresholding
IEEE Access, 2019 The Hankel matrix of harmonic signals has the important low-rank property, based on which the principal components (or the eigenvectors) extracted from the matrix by singular value decomposition (SVD) could be applied for harmonic signal denoising ...

Electronic model for CoO2 layer based systems: chiral resonating valence bond metal and superconductivity. [PDF]
Physical Review Letters, 2003 Takada et al. have reported superconductivity in layered Na(x)CoO(2)yH(2)O (T(c) approximately equal to 5 K). We model a reference neutral CoO2 layer as an orbitally nondegenerate spin-1/2 antiferromagnetic Mott insulator on a triangular lattice and Na(x)

Localization properties of a tight-binding electronic model on the Apollonian network [PDF]
, 2008 An investigation on the properties of electronic states of a tight-binding Hamiltonian on the Apollonian network is presented. This structure, which is defined based on the Apollonian packing problem, has been explored both as a complex network, and as a
