Linear and nonlinear spectroscopy from quantum master equations
Jonathan H. Fetherolf, Timothy C. Berkelbach
We investigate the accuracy of the second-order time-convolutionless (TCL2) quantum master equation for the calculation of linear and nonlinear spectroscopies of multichromophore s…
Environmentally-Sensitive Theory of Electronic and Optical Transitions in Atomically-Thin Semiconductors
Yeongsu Cho, Timothy C. Berkelbach
We present an electrostatic theory of band gap renormalization in atomically-thin semiconductors that captures the strong sensitivity to the surrounding dielectric environment. In…
Gaussian and plane-wave mixed density fitting for periodic systems
Qiming Sun, Timothy C. Berkelbach, James D. McClain +1
We introduce a mixed density fitting scheme that uses both a Gaussian and a plane-wave fitting basis to accurately evaluate electron repulsion integrals in crystalline systems. We…
Coulomb engineering of the bandgap in 2D semiconductors
Archana Raja, Andrey Chaves, Jaeeun Yu +13
The ability to control the size of the electronic bandgap is an integral part of solid-state technology. Atomically-thin two-dimensional crystals offer a new approach for tuning th…
On the accuracy of the Pade-resummed master equation approach to dissipative quantum dynamics
Hsing-Ta Chen, Timothy C. Berkelbach, David R. Reichman
Well--defined criteria are proposed for assessing the accuracy of quantum master equations whose memory functions are approximated by Padé resummation of the first two moments in t…
