Accurate computation of quantum excited states with neural networks

Science, 2023
We present an algorithm to estimate the excited states of a quantum system by variational Monte Carlo, which has no free parameters and requires no orthogonalization of the states, instead transforming the problem into that of finding the ground state of

Polysilane excited states and excited state dynamics

Chemical Physics, 1990
Abstract Femtosecond time-resolved excited state absorption spectroscopy is used to reveal excited states of linear-chain poly(di- n -hexylsilane) about 1 eV and in the range of 3.5 eV above the lowest excited state. A description of the excited state dynamics following optical excitation in polysilanes is presented. The concept of conjugation length

Excited-State Properties

2011
This chapter provides a general overview of photochemistry and photophysics, starting with photochemical processes in everyday life and the nature of light. Then, a discussion about formation of electronic excited states by light absorption is presented together with their deactivation processes.
