Two-dimensional electronic spectroscopy (2DES) is a popular technique that can track
ultrafast coherent and incoherent processes in real time. Since its development in the late …

Ultrafast spectroscopy techniques use sequences of ultrashort light pulses (with femto-to
attosecond durations) to study photoinduced dynamical processes in atoms, molecules …

Quantum entanglement has emerged as a great resource for spectroscopy and its
importance in two-photon spectrum and microscopy has been demonstrated. Current …

In atomically thin transition metal dichalcogenides (TMDs), reduced dielectric screening of
the Coulomb interaction leads to strongly correlated many-body states, including excitons …

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 …

Magnons are quantized collective spin-wave excitations in magnetically ordered materials.
Revealing the interactions among these collective modes is crucial for the understanding of …

Quantum states depend on the coordinates of all their constituent particles, with essential
multi-particle correlations. Time-resolved laser spectroscopy is widely used to probe the …

The temporal characterization of ultrafast laser pulses has become a cornerstone capability
of ultrafast optics laboratories and is routine both for optimizing laser pulse duration and …

Interactions between two excitons can result in the formation of bound quasiparticles, known
as biexcitons. Their properties are determined by the constituent excitons, with orbital and …

Most experiments on multiexcitons (MX) in quantum dots focused on the biexciton (XX),
which is now well-understood. In contrast, there is little understanding of higher MX in …
