Cocrystal engineering, involving the assembly of two or more components into a highly
ordered solid-state superstructure, has emerged as a popular strategy for tuning the …

Two-photon excited near-infrared fluorescence materials have garnered considerable
attention because of their superior optical penetration, higher spatial resolution, and lower …

The use of a nonclassical light source for studying molecular electronic structure has been of
great interest in many applications. Here we report a theoretical study of entangled two …

The emergence of X-ray free electron lasers (X-FELs) has made it possible to probe
structural dynamics on the femtosecond timescale. This extension of experimental …

We report how the unique temporal and spectral features of pulsed entangled photons from
a parametric downconversion source can be utilized for manipulating electronic excitations …

Investigations of the ground and excited states absorption are very important for the
development of advanced optical limiters. Linear response time-dependent density …

In the present paper, the aggregated structures of zinc phthalocyanine (ZnPc) have been
investigated by considering its dimers and trimers. Based on the density functional theory …

The excited-state absorption in a set of fluorene oligomers are simulated based on the LR-
TDDFT and QR-TDDFT calculations. It is shown that the results obtained from LR-TDDFT …

Singlet fission (SF) has the potential to dramatically increase solar cell efficiency by
converting one singlet exciton to two free triplet excitons via a correlated triplet pair …

Applications of low-cost non-perturbative approaches in real time, such as time-dependent
density functional theory, for the study of nonlinear optical properties of large and complex …
