Non-Reciprocal Capillary Waves
Holly du Plessis, Pedro Cosme, Hugo França +1
Capillary waves are a classical free-surface phenomenon in fluid mechanics, yet their behavior in chiral fluids remains largely unexplored. We show that odd viscosity breaks the re…
Hydrodynamics in generalized electronic two-band systems
E. Di Salvo, P. Cosme, L. Fritz
In this paper, we derive the Euler and Navier-Stokes equations for electronic two-band systems in arbitrary dimension and with generic power-law dispersion relations. We focus on t…
The shear viscosity of interacting graphene
Kitinan Pongsangangan, Pedro Cosme, Emanuele Di Salvo +1
One of the hallmark properties of fluids is their shear viscosity which is, among other things, responsible for parabolic flow profiles through narrow channels. In recent years, th…
Feedback enhanced Dyakonov-Shur instability in Graphene-FET
Pedro Cosme, Diogo Simões
Graphene devices are known to have the potential to operate THz signals. In particular, graphene field-effect transistors have been proposed as devices to host plasmonic instabilit…
Topological waves in the continuum in magnetized graphene devices
A. Ciobanu, P. Cosme, H. Terças
We show that topological waves at the interface between two magnetic domains in a graphene device are possible. First, we consider the case of a linear relation between the applied…
Conductance suppression due to two-stream instability in bilayer graphene
Vasco Pinhão, Pedro Cosme, Hugo Terças
We investigate the electron-hole two-stream instability (or Coulomb drag) in intrinsic bilayer graphene in the hydrodynamic regime, accounting for the effects of temperature, initi…
Hydrodynamic electrons in Graphene: a viscous boundary-layer description
Pedro Cosme, João S. Santos, Hugo Terças
In this paper we dwell over the study of the boundary layer problem in a hydrodynamical description of the electrons in gated graphene. It has been verified experimentally that thi…
Nonlinear density waves on graphene electron fluids
Pedro Cosme, Hugo Terças
In graphene, where the electron-electron scattering is dominant, electrons collectively act as a fluid. This hydrodynamic behaviour of charge carriers leads to exciting nonlinear p…
Hydrodynamical study of Terahertz emission in magnetized graphene field-effect transistors
Pedro Cosme, Hugo Terças
Several hydrodynamic descriptions of charge transport in graphene have been presented in the late years. We discuss a general hydrodynamic model governing the dynamics of a two-dim…
Terahertz Laser Combs in Graphene Field-Effect Transistors
Pedro Cosme, Hugo Terças
Electrically injected terahertz (THz) radiation sources are extremely appealing given their versatility and miniaturization potential, opening the venue for integrated-circuit THz…
