Functional Integral approach to time-dependent heat exchange in open quantum systems: general method and applications
M. Carrega, P. Solinas, A. Braggio +2
We establish the path integral approach for the time-dependent heat exchange of an externally driven quantum system coupled to a thermal reservoir. We derive the relevant influence…
Highly confined low-loss plasmons in graphene-boron nitride heterostructures
Achim Woessner, Mark B. Lundeberg, Yuanda Gao +10
Graphene plasmons were predicted to possess ultra-strong field confinement and very low damping at the same time, enabling new classes of devices for deep subwavelength metamateria…
Plasmon losses due to electron-phonon scattering: the case of graphene encapsulated in hexagonal Boron Nitride
Alessandro Principi, Matteo Carrega, Mark Lundeberg +4
Graphene sheets encapsulated between hexagonal Boron Nitride (hBN) slabs display superb electronic properties due to very limited scattering from extrinsic disorder sources such as…
Multiple quasiparticle Hall spectroscopy investigated with a resonant detector
D. Ferraro, M. Carrega, A. Braggio +1
We investigate the finite frequency (f.f.) noise properties of edge states in the quantum Hall regime. We consider the measurement scheme of a resonant detector coupled to a quantu…
Electron-hole pairing in graphene-GaAs heterostructures
A. Gamucci, D. Spirito, M. Carrega +8
Vertical heterostructures combining different layered materials offer novel opportunities for applications and fundamental studies of collective behavior driven by inter-layer Coul…
