The Flowing BIon
Gianluca Grignani, Troels Harmark, Callum Kift +2
In this paper we use the effective blackfold description of branes to extend the study of the thermal BIon, a D-brane and parallel anti-D-brane connected by a wormhole with F-strin…
The Nonlinear Optical Effects of Opening a Gap in Graphene
David N. Carvalho, Andrea Marini, Fabio Biancalana
Graphene possesses remarkable electronic, optical and mechanical properties that have taken the research of two-dimensional relativistic condensed matter systems to prolific levels…
Ab initio calculations of ultra-short carrier dynamics in 2D materials: valley depolarization in single-layer WSe
Alejandro Molina-Sánchez, Davide Sangalli, Ludger Wirtz +1
In single-layer WSe, a paradigmatic semiconducting transition metal dichalcogenide, a circularly polarized laser field can selectively excite electronic transitions in one of t…
Phase-matching-free parametric oscillators based on two dimensional semiconductors
A. Ciattoni, A. Marini, C. Rizza +1
Optical parametric oscillators are widely-used pulsed and continuous-wave tunable sources for innumerable applications, as in quantum technologies, imaging and biophysics. A key dr…
Photo-Induced Bandgap Renormalization Governs the Ultrafast Response of Single-Layer MoS2
Eva A. A. Pogna, Margherita Marsili, Domenico De Fazio +9
Transition metal dichalcogenides (TMDs) are emerging as promising two-dimensional (2d) semiconductors for optoelectronic and flexible devices. However, a microscopic explanation of…
Petahertz optical response in graphene
Matthias Baudisch, Andrea Marini, Joel D. Cox +8
The temporal dynamics of charge carriers determines the speed with which electronics can be realized in condensed matter, and their direct manipulation with optical fields promises…
