Exciton–exciton annihilation and biexciton stimulated emission in graphene nanoribbons
Giancarlo Soavi,Giancarlo Soavi,Stefano Dal Conte,Cristian Manzoni,Daniele Viola,Akimitsu Narita,Yunbin Hu,Xinliang Feng,Ulrich Hohenester,Elisa Molinari,Deborah Prezzi,Klaus Müllen,Giulio Cerullo +12 more
TL;DR: It is shown that in the high-excitation regime biexcitons are formed by nonlinear exciton–exciton annihilation, and that they radiatively recombine via stimulated emission, in very good agreement with theoretical results from quantum Monte Carlo simulations.
Journal ArticleDOI
Witnessing the formation and relaxation of dressed quasi-particles in a strongly correlated electron system
Fabio Novelli,Fabio Novelli,Giulio De Filippis,Vittorio Cataudella,Martina Esposito,Ignacio Vergara,Federico Cilento,Enrico Sindici,Adriano Amaricci,Claudio Giannetti,Dharmalingam Prabhakaran,Simon Wall,Andrea Perucchi,Stefano Dal Conte,Giulio Cerullo,Massimo Capone,Andrey S. Mishchenko,Andrey S. Mishchenko,Markus Grüninger,Naoto Nagaosa,Naoto Nagaosa,Fulvio Parmigiani,Fulvio Parmigiani,Fulvio Parmigiani,Daniele Fausti,Daniele Fausti +25 more
TL;DR: It is revealed that sub-gap excitation pilots the formation of itinerant quasi-particles, which are suddenly dressed by an ultrafast reaction of the bosonic field.
Journal ArticleDOI
Ultrafast insulator-to-metal phase transition as a switch to measure the spectrogram of a supercontinuum light pulse
Federico Cilento,Federico Cilento,Claudio Giannetti,Gabriele Ferrini,Stefano Dal Conte,Tommaso Sala,Giacomo Coslovich,Giacomo Coslovich,M. Rini,Andrea Cavalleri,Andrea Cavalleri,Fulvio Parmigiani +11 more
TL;DR: In this paper, the temporal and spectral structure (spectrogram) of a complex light pulse exploiting the ultrafast switching character of a nonthermal photoinduced phase transition is demonstrated. But the method is limited to femtosecond near-infrared laser pulses.
Journal ArticleDOI
Optical parametric amplification by monolayer transition metal dichalcogenides
Chiara Trovatello,Chiara Trovatello,Andrea Marini,Xinyi Xu,Changhwan Lee,Fang Liu,Nicola Curreli,Nicola Curreli,Cristian Manzoni,Stefano Dal Conte,Kaiyuan Yao,Alessandro Ciattoni,James Hone,Xiaoyang Zhu,P. James Schuck,Giulio Cerullo +15 more
TL;DR: In this article, a single-pass optical parametric amplification at the ultimate thickness limit was demonstrated using semiconducting transition metal dichalcogenides, where an optical signal is amplified by a pump via the generation of an idler field.
Journal ArticleDOI
The ultrafast onset of exciton formation in 2D semiconductors.

TL;DR: An ultimate timescale of the exciton formation in TMDs is set and a phonon-mediated exciton cascade from higher energy states to the ground excitonic state is found to be the rate-limiting process.
