Effects of opposite atoms on electronic structure and optical absorption of two-dimensional hexagonal boron nitride
You-Zhao Lan
We perform the first-principles many-body GW and Bethe-Salpeter equation (BSE) calculations on the two-dimensional hexagonal boron nitride (2D-hBN) to explore the effects of opposi…
Excitonic effects on the third-order nonlinear optical properties of solids: Theory and application
You-Zhao Lan
We present a many-body Bethe-Salpeter equation eigenstates based sum-over-states method to calculate the linear and nonlinear optical properties of solids. Excitonic and local fiel…
Excitonic effect on two-photon absorption of two-dimensional semiconductors: Theory and applications to MoS2 and WS2 monolayers
You-Zhao Lan, Xiao-Hu Bao
Based on the Bethe-Salpeter equation eigenstates, we present a first-principles many-body formalism for calculating the two-photon absorption (TPA) coefficient of semiconductors. W…
Origin of layer number dependent linear and nonlinear optical properties of two-dimensional graphene-like SiC
You-Zhao Lan
We theoretically discuss the physical origin of the dielectric constants [ε(ω)] and second harmonic generation coefficients [\{chi}(2)(ω)] of the ABA-stacked two-dimensional graphe…
Full ab initio band structure analysis of interband and intraband contributions for third harmonic generation coefficient of bulk silicon: implementation and application of the sum-over-states
You-Zhao Lan
We fully implement the Aversa and Sipe sum-over-states formulism and make a full ab initio band structure analysis of interband and intraband contributions for the third-order nonl…
Comprehensive understanding of size-, shape-, and composition-dependent polarizabilities of SimCn (m, n = 1-4) clusters
You-Zhao Lan, Hong-Lan Kang, Tao Niu
We theoretically investigate the size-, shape-, and composition-dependent polarizabilities of the SimCn (m, n = 1 - 4) clusters by using the density functional based coupled pertur…
Dynamic second-order hyperpolarizabilities of Si2C and Si3C clusters using coupled cluster singles-and-doubles response approach
You-Zhao Lan, Yun-Long Feng
We investigate the dynamic second-order hyperpolarizabilities γ(-3ω; ω, ω, ω) (indicated by γTHG) of the Si2C and Si3C clusters using the highly accurate coupled cluster singles-an…
