Fluctuation theorems (FTs), which describe some universal properties of nonequilibrium
fluctuations, are examined from a quantum perspective and derived by introducing a two …

The ability to measure the behavior of a single molecule during a reaction implies the
detection of inherent dynamic and static disordered states, which may not be represented …

Conventional analytic techniques that measure ensemble averages and static disorder
provide essential knowledge of the reaction mechanisms of organic and organometallic …

We provide here a brief perspective on the glass transition field. It is an assessment, written
from the point of view of theory, of where the field is and where it seems to be heading. We …

The motion of chemical bonds within molecules can be observed in real time in the form of
vibrational wave packets prepared and interrogated through ultrafast nonlinear …

Single-molecule measurements provide unique information on heterogeneous populations
of molecules: They give access to the complete distribution of observables (rather than only …

After photoexcitation, energy absorbed by a molecule can be transferred efficiently over a
distance of up to several tens of angstroms to another molecule by the process of resonance …

We overview experimental and theoretical studies of energy transfer in the photosynthetic
light-harvesting complexes LH1, LH2, and LHCII performed during the past decade since …

We investigate the polarization selection rules of sharp zero-phonon lines (ZPLs) from
isolated defects in hexagonal boron nitride (HBN) and compare our findings with the …

Optical imaging and analysis of single molecules continue to unfold as powerful ways to
study the individual behavior of biological systems, unobscured by ensemble averaging …
