Frustrated magnetic interactions in a cyclacene crystal
R. Ortiz, J. C. Sancho-García, J. Fernández-Rossier
We study the emergence of magnetism and its interplay with structural properties in a two dimensional molecular crystal of cyclacenes, using density functional theory (DFT). Isolat…
Testing complementarity on a transmon quantum processor
Pedro M. Q. Cruz, J. Fernández-Rossier
We propose quantum circuits to test interferometric complementarity using symmetric two-way interferometers coupled to a which-path detector. First, we consider the two-qubit setup…
Renormalization of spin excitations and Kondo effect in open shell nanographenes
David Jacob, Ricardo Ortiz, Joaquín Fernández-Rossier
We study spin excitations and Kondo effect in open-shell nanographenes, motivated by recent scanning tunneling inelastic spectroscopy experiments. Specifically, we consider three s…
Gutzwiller wave function on a digital quantum computer
Bruno Murta, Joaquín Fernández-Rossier
The determination of the ground state of quantum many-body systems via digital quantum computers rests upon the initialization of a sufficiently educated guess. This requirement be…
Probing local moments in nanographenes with electron tunneling spectroscopy
Ricardo Ortiz, Joaquín Fernández-Rossier
The emergence of local moments in graphene zigzag edges, grain boundaries, vacancies and sp3 defects has been widely studied theoretically. However, conclusive experimental evidenc…
Excitonic Magneto-Optical Kerr Effect in 2D Transition Metal Dichalcogenides Induced by Spin Proximity
J. C. G. Henriques, G. Catarina, A. T. Costa +2
In this paper we develop the excitonic theory of Kerr rotation angle in a two-dimensional (2D) transition metal dichalcogenide at zero magnetic field. The finite Kerr angle is indu…
