In this work we present a fully relativistic formulation for the energy loss of an external charged particle interacting with a 2D material. We model this material as a monolayer of atoms represented by harmonic oscillators, with isotropic or anisotr

In this work, we propose a unified model to evaluate processes of electronic interactions of charged particles with hot and dense matter, including energy losses, mean free paths, and thermalization ranges of protons or other light ions. To formulate

We apply a fully relativistic formulation to calculate the average number of plasmons excited by an energetic electron traversing two parallel graphene layers separated by a given distance d. We use a Drude model in the non-dissipative limit to descr

We present a fully relativistic formulation for the energy loss rate of a charged particle moving parallel to a sheet containing two-dimensional electron gas, allowing that its in-plane polarization may be described by different longitudinal and tran

We assess the applicability of the oscillator model to evaluate the energy loss of a fast charged particle incident on graphene. We study the cases of a parallel and perpendicular trajectory of the particle. We focus on two frequency regimes for grap

We address the problem of quantifying the decay of plasmons excited in the electron gas of a condensed medium. Within the dielectric formalism, we thoroughly describe the theoretical framework in which we define the damping parameter γ. We present t

We present a fully relativistic formulation of the energy loss of a charged particle traversing a number of graphene layers and apply it to the case of two spatially separated layers probed by an energetic electron. We focus on the THz frequency rang
