Strongly coupled magnon-plasmon polaritons in graphene- 2D ferromagnet heterostructures
A. T. Costa, M. I. Vasilevskiy, J. Fernández-Rossier +1
Magnons and plasmons are two very different types of collective modes, acting on the spin and charge degrees of freedom, respectively. At first sight, the formation of hybrid plasm…
Wannier Excitons Confined in Hexagonal Boron Nitride Triangular Quantum Dots
M. F. C. Martins Quintela, N. M. R. Peres
With the ever-growing interest in quantum computing, understanding the behaviour of excitons in monolayer quantum dots has become a topic of great relevance. In this paper, we cons…
Curvature-induced repulsive effect on the lateral Casimir-Polder--van der Waals force
Danilo T. Alves, Lucas Queiroz, Edson C. M. Nogueira +1
We consider a perfectly conducting infinite cylinder with radius , and investigate the Casimir-Polder (CP) and van der Waals (vdW) interactions with a neutral polarizable partic…
Contribution to Excitonic Linewidth from Free Carrier-Exciton Scattering in Layered Materials: The example of h-BN
M. F. C. Martins Quintela, N. M. R. Peres
Scattering of excitons by free carriers is a phenomena which is especially important when considering moderately to heavily doped semiconductors in low temperature experiments, whe…
Excitonic instability in transition metal dichalcogenides
M. F. C. Martins Quintela, A. T. Costa, N. M. R. Peres
When transition-metal dichalcogenide monolayers lack inversion symmetry, their low-energy single particle spectrum can described by tilted massive Dirac Hamiltonians. The so-called…
Laser induced enhanced coupling between photons and squeezed magnons in antiferromagnets
J. C. G. Henriques, T. V. C. Antão, N. M. R. Peres
In this paper we consider a honeycomb antiferromagnet subject to an external laser field. Obtaining a time-independent effective Hamiltonian, we find that the external laser renorm…
