The interaction between a mobile quantum impurity and a bosonic bath leads to the
formation of quasiparticles, termed Bose polarons. The elementary properties of Bose …

Metal-halide perovskites (MHPs) with unique electronic and optical properties have
emerged as promising materials with a broad spectrum of applications in photovoltaics …

Fermi polarons are emerging quasiparticles when a bosonic impurity immersed in a
fermionic bath. Depending on the boson-fermion interaction strength, the Fermi-polaron …

Nonlinear optics has long been a cornerstone of modern photonic technology, enabling a
wide array of applications, from frequency conversion to the generation of ultrafast light …

We use time-resolved nonlinear pump--probe measurements to reveal features of
semiconductor moir\'e materials not accessible to linear spectroscopy. With an intense, red …

We use femtosecond pump-probe spectroscopy to study the coherent interaction of excited
exciton states in WSe2 and MoSe2 monolayers via the optical Stark effect. For co-circularly …

Recently, light-matter interaction has been vastly expanded as a control tool for inducing
and enhancing many emergent non-equilibrium phenomena. However, conventional …
