Over the past few decades, coherent broadband spectroscopy has been widely used to
improve our understanding of ultrafast processes (eg, photoinduced electron transfer, proton …

Coherence refers to correlations in waves. Because matter has a wave-particle nature, it is
unsurprising that coherence has deep connections with the most contemporary issues in …

Interactions between quasiparticles are of fundamental importance and ultimately determine
the macroscopic properties of quantum matter. A famous example is the phenomenon of …

Two-dimensional electronic spectroscopy (2DES) reveals connections between an optical
excitation at a given frequency and the signals it creates over a wide range of frequencies …

Owing to both electronic and dielectric confinement effects, two-dimensional organic-
inorganic hybrid perovskites sustain strongly bound excitons at room temperature. Here, we …

Dual laser frequency combs can rapidly measure high-resolution linear absorption spectra.
However, one-dimensional linear techniques cannot distinguish the sources of resonances …

With strongly bound and stable excitons at room temperature, single-layer, two-dimensional
organic-inorganic hybrid perovskites are viable semiconductors for light-emitting quantum …

Recent measurements using two-dimensional electronic spectroscopy (2D ES) have shown
that the initial dynamic response of photosynthetic proteins can involve quantum coherence …

The advent of laser-based sources of ultrafast infrared pulses has extended the study of very
fast molecular dynamics to the observation of processes manifested through their effects on …

Multidimensional spectroscopy at visible and infrared frequencies has opened a window
into the transfer of energy and quantum coherences at ultrafast time scales. For these …
