Excitonic Stark effect inMoS2monolayers

Excitonic Interactions and Stark Spectroscopy of Light Harvesting Systems

A closed expression for the Stark signal of molecular aggregates, which does not suffer from singularities when the exciton states are nearly degenerate and avoids the calculation of two-exciton states, is derived from the third order response to the total (static + optical) field, treating intermolecular interactions within the local field approximation. Transitions between one-exciton states ...

Stark Effect

An electric field partly lifts the degeneracies of atomic energy levels. This splitting was observed by Stark [1] and explained by Schrödinger [2]. We compute the Stark effect on atomic hydrogen using perturbation theory by diagonalizing the perturbation term in the N-fold degenerate multiplet of states with principal quantum number N . We exploit the symmetries of this problem to simplify the ...

The Covariant Stark Effect

This paper examines the Stark effect, as a first order perturbation of manifestly covariant hydrogen-like bound states. These bound states are solutions to a relativistic Schrödinger equation with invariant evolution parameter, and represent mass eigenstates whose eigenvalues correspond to the well-known energy spectrum of the nonrelativistic theory. In analogy to the nonrelativistic case, the ...

Excitonic Dynamical Franz-Keldysh Effect

Stark effect spectroscopy of tryptophan.

The change in permanent dipole moment (magnitude of delta mu) for the transition from the 1La state to the ground state of tryptophan is the key photophysical parameter for the interpretation of tryptophan fluorescence spectra in terms of static and dynamic dielectric properties of the surrounding medium. We report measurement of this parameter by means of electric field effect (Stark) spectros...
