Description
In this work, we explore the dynamics of coupled quantum systems comprising both
fermionic and bosonic particles, focusing on their collective behaviors and emergent
phenomena in graphene. Conventional research frequently isolates a main species and
examines its characteristics either independently of or in equilibrium with nearby
species. Here we diverge by studying mixed systems with complex interactions between
bosons and fermions, with particular emphasis on bosonic charge density oscillations,
called plasmons. We use a kinetic theory framework that quantizes both bosonic and
fermionic particles, in contrast to traditional methods that treat fields classically. By
incorporating non linear effective forces to couple and correlate the various species, we
are able to provide a more thorough understanding of their dynamics. With this kinetic
approach we will uncover new modes and instabilities within the plasma dynamics,
offering insights into the complex behaviors underpinning coupled fermi-boson systems.
