Terahertz cavity hybridization of collective proteins vibrations
Elsa Perez-Martin, Laurent Bonnet, Songlin Fang +8
Hybrid light-matter states have transformed photonics, yet their realization with driven collective vibrations in biological systems remains an open challenge. Here we show that op…
Resonant Dyakonov-Shur Magnetoplasmons in Graphene Terahertz Photodetectors
Juan A. Delgado-Notario, Cedric Bray, Elsa Perez-Martin +16
Graphene plasmons confine incident terahertz fields far below the diffraction limit and, when hosted by a gate-defined Fabry-Perot cavity, enable electrically tunable, frequency-se…
Spin-dependent photovoltage in graphene/MoS2-based field-effect transistors
K. Dinar, J. Delgado-Notario, C. Bray +14
It has recently been shown that Terahertz sensors can effectively detect the spin resonances of Dirac fermions in graphene. The associated photovoltaic measurement technique allows…
Unveiling Long-Range Forces in Light Harvesting Proteins: Pivotal Roles of Temperature and Light
Elsa Perez-Martin, Tristan Beranger, Laurent Bonnet +11
Electrodynamic interactions between biomolecules are of potential biological interest for signaling warranting investigation of their activation through various mechanisms in livin…
Multi-probe analysis to separate edge currents from bulk currents in quantum spin Hall insulators and to analyze their temperature dependence
S. Benlenqwanssa, S. S. Krishtopenko, M. Meyer +13
We present a multi-probe transport analysis that effectively separates bulk and edge currents in large Hall bar devices with standard geometries. Applied to transport measurements…
