Surface hopping modeling of two-dimensional spectra.

Recently, two-dimensional (2D) electronic spectroscopy has become an important tool to unravel the excited state properties of complex molecular assemblies, such as biological light harvesting systems. In this work, we propose a method for simulating 2D electronic spectra based on a surface hopping approach. This approach self-consistently describes the interaction between photoactive chromopho...

Appraisal of Surface Hopping as a Tool for Modeling Condensed Phase Linear Absorption Spectra.

Whereas surface hopping is usually used to study populations and mean-field dynamics to study coherences, in two recent papers, we described a procedure for calculating dipole-dipole correlation functions (and therefore absorption spectra) directly from ensembles of surface hopping trajectories. We previously applied this method to a handful of one-dimensional model problems intended to mimic t...

Shot-noise suppression at two-dimensional hopping

We have used Monte Carlo simulation to calculate the shot-noise intensity SI(v) at ~two-dimensional! hopping using two models: a slanted lattice of localized sites with equal energies and a set of localized sites with random positions and energies. For wide samples we have found a similar dependence of the Fano factor F[SI(0)/2eI on the sample length L: F}L 2a where a50.8560.02 and a50.8560.07 ...

The two-dimensional Anderson model of localization with random hopping

We examine the localization properties of the 2D Anderson Hamiltonian with off-diagonal disorder. Investigating the behavior of the participation numbers of eigenstates as well as studying their multifractal properties, we find states in the center of the band which show critical behavior up to the system size N = 200×200 considered. This result is confirmed by an independent analysis of the lo...

The BPS spectra of Two - Dimensional Supersymmetric

The vacuum structure and spectra of two-dimensional gauge theories with N = (2, 2) supersymmetry are investigated. These theories admit a twisted mass term for charged chiral matter multiplets. In the case of a U(1) gauge theory with N chi-ral multiplets of equal charge, an exact description of the BPS spectrum is obtained for all values of the twisted masses. The BPS spectrum has two dual desc...
