Combining density functional theory with macroscopic QED for quantum light-matter interactions in 2D materials
Autor: Mark Kamper Svendsen, Yaniv Kurman, Peter Schmidt, Frank Koppens, Ido Kaminer, Kristian S. Thygesen
Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-13 (2021)
The development of a quantitative and predictive theory of quantum light-matter interactions in ultrathin materials is both a conceptual and computational challenge. Here, the authors develop such a framework by combining density functional theory wi

Autor: Matthias Baudisch, Andrea Marini, Joel D. Cox, Tony Zhu, Francisco Silva, Stephan Teichmann, Mathieu Massicotte, Frank Koppens, Leonid S. Levitov, F. Javier García de Abajo, Jens Biegert
Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-6 (2018)
Graphene possesses a nonlinear optical response arising from its electronic dispersion. Here, the authors measure the response of graphene to an ultrafast optical field and provide an explanation of the quantum dynamics of Dirac carriers mediating th

Ultrafast carrier dynamics in graphene and graphene nanostructures
Autor: Dmitry Turchinovich, Zoltan Mics, Søren A. Jensen, Klaas-Jan Tielrooij, Ivan Ivanov, Khaled Parvez, Akimitsu Narita, Tobias Hertel, Frank Koppens, Xinliang Feng, Klaus Müllen, Mischa Bonn
Publikováno v: Terahertz Science and Technology. 13:135-148
In this paper we provide a comprehensive view on the ultrafast conduction dynamics in graphene and graphene nanostructures. We show that ultrafast conduction in graphene can be well understood within a simple thermodynamic picture, by taking into acc

Dynamics of optical vortices in 2D materials
Autor: Yaniv Kurman, Raphael Dahan, Hanan Sheinfux, Gilles Rosolen, Eli Jenzen, James Edgar, Frank Koppens, Ido Kaminer
Quantized vortices are topological defects found in different two-dimensional geometries, from liquid crystals to ferromagnets, famously involved in spontaneous symmetry breaking and phase transitions. Their optical counterparts appear in planar geom

Graphene-CMOS integration for broadband imaging and integrated photonics: Prospects and prototypes
Autor: Frank Koppens
Publikováno v: Advanced Photonics 2018 (BGPP, IPR, NP, NOMA, Sensors, Networks, SPPCom, SOF).
We show several applications of graphene-CMOS integration. This includes the first monolithic integration of an electronic CMOS integrated circuit with graphene, operating as a broadband photodetector. We will show several examples of 2d material het

Graphene flagship: From lab to society
Autor: Frank Koppens
Publikováno v: ICTON
The long list of unique properties for graphene and 2d materials have been the major driver for intense scientific research. Interestingly, it is this same list of unique properties that have also been the justification for the advances in technologi
