Quasiparticle phono-conversion: filming carriers coalescing into excitons
Enrico Perfetto, Takumi Fukuda, Xing Zhu +12
Condensed matter physics is replete with phenomena involving high-energy free particles coalescing into low-energy bound few-particle states. While the cooling of the individual pa…
Excitonic effects in the photocarriers dynamics of two-dimensional materials
Carlos Betancur, Gianluca Stefanucci, Enrico Perfetto
We investigate the role of excitonic correlations in shaping the ultrafast dynamics of photoexcited carriers in semiconductors. Conventional approaches describe relaxation within s…
Excitonic Mott transition without population inversion
Oleg Dogadov, Armando Genco, Allison R. Cadore +12
Exciton dissociation via the excitonic Mott transition (EMT) governs the high-density optical response of semiconductors and sets fundamental limits for optoelectronic devices. The…
Ultrafast nonlinear Hall effect in black phosphorus
Maciej Dendzik, Andrea Marini, Samuel Beaulieu +9
The nonlinear Hall effect (NHE) is a recently discovered member of the Hall effect family in which the Hall voltage shows a nonlinear behavior when a transverse electric field is a…
Unified First-Principles Formula for Time-Resolved ARPES Spectra of Coherent and Incoherent Excitons
Gianluca Stefanucci, Enrico Perfetto
Despite major experimental progresses in time-resolved and angle-resolved photoemission spectroscopy, a quantitative, microscopic framework for interpreting exciton-induced modific…
Exceptional Excitons
Enrico Perfetto, Gianluca Stefanucci
Non-Hermitian physics is reshaping our understanding of quantum systems by revealing states and phenomena without Hermitian counterparts. While non-Hermiticity is typically associa…
