Exciton-phonon coupling strength in single-layer MoSe2 at room temperature
Donghai Li, Chiara Trovatello, Stefano Dal Conte +6
Single-layer transition metal dichalcogenides are at the center of an ever increasing research effort both in terms of fundamental physics and applications. Exciton-phonon coupling…
Investigation of the Non-equilibrium State of Strongly Correlated Materials by Complementary Ultrafast Spectroscopy Techniques
Hamoon Hedayat, Charles J. Sayers, Arianna Ceraso +6
Photoinduced non-thermal phase transitions are new paradigms of exotic non-equilibrium physics of strongly correlated materials. An ultrashort optical pulse can drive the system to…
Tunable broadband light emission from graphene
Lavinia Ghirardini, Eva A. A. Pogna, Giancarlo Soavi +12
Graphene is an ideal material for integrated nonlinear optics thanks to its strong light-matter interaction and large nonlinear optical susceptibility. Graphene has been used in op…
Superabsorption in an organic microcavity: towards a quantum battery
J. Q. Quach, K. E. McGhee, L. Ganzer +7
The rate at which matter emits or absorbs light can be modified by its environment, as dramatically exemplified by the widely-studied phenomenon of superradiance. The reverse proce…
Tuning the Ultrafast Response of Fano Resonances in Halide Perovskite Nanoparticles
Paolo Franceschini, Luca Carletti, Anatoly P. Pushkarev +12
The full control of the fundamental photophysics of nanosystems at frequencies as high as few THz is key for tunable and ultrafast nano-photonic devices and metamaterials. Here we…
Coherent phonons and the interplay between charge density wave and Mott phases in 1-TaSe
C. J. Sayers, H. Hedayat, A. Ceraso +9
1-TaSe is host to coexisting strongly-correlated phases including charge density waves (CDWs) and an unusual Mott transition at low temperature. Here, we investigate coher…
Transient optical symmetry breaking for ultrafast broadband dichroism in plasmonic metasurfaces
Andrea Schirato, Margherita Maiuri, Andrea Toma +7
Ultrafast nanophotonics is an emerging research field aimed at the development of nanodevices capable of light modulation with unprecedented speed. A promising approach exploits th…
Non-equilibrium Band Broadening, Gap Renormalization and Band Inversion in Black Phosphorus
H. Hedayat, A. Ceraso, G. Soavi +6
Black phosphorous (BP) is a layered semiconductor with high carrier mobility, anisotropic optical response and wide bandgap tunability. In view of its application in optoelectronic…
Conformable nanowire-in-nanofiber hybrids for low-threshold optical gain in the ultraviolet
Alberto Portone, Rocio Borrego-Varillas, Lucia Ganzer +6
The miniaturization of diagnostic devices that exploit optical detection schemes requires the design of light-sources combining small size, high performance for effective excitatio…
The ultrafast onset of exciton formation in 2D semiconductors
Chiara Trovatello, Florian Katsch, Nicholas J. Borys +11
The equilibrium and non-equilibrium optical properties of single-layer transition metal dichalcogenides (TMDs) are determined by strongly bound excitons. Exciton relaxation dynamic…
