Ionisation rate and Stark shift of a one-dimensional model of the Hydrogen molecular ion
J. C. G. Henriques, Thomas G. Pedersen, N. M. R. Peres
In this paper we study the ionization rate and the Stark shift of a one-dimensional model of the H ion. The finding of these two quantities is reduced to the solutions of…

Harnessing Ultraconfined Graphene Plasmons to Probe the Electrodynamics of Superconductors
A. T. Costa, P. A. D. Gonçalves, D. N. Basov +3
We show that the Higgs mode of a superconductor, which is usually challenging to observe by far-field optics, can be made clearly visible using near-field optics by harnessing ultr…

Excitons in hexagonal boron nitride single-layer: a new platform for polaritonics in the ultraviolet
F. Ferreira, A. J. Chaves, N. M. R. Peres +1
The electronic and optical properties of 2D hexagonal boron nitride are studied using first principle calculations. GW and BSE methods are employed in order to predict with better…
