Antiferromagnetic phase diagram of the cuprate superconductors
Lizardo H. C. M. Nunes, A. W. Teixeira, E. C. Marino
Taking the spin-fermion model as the starting point for describing the cuprate superconductors, we obtain an effective nonlinear sigma-field hamiltonian, which takes into account t…
Temperature vs. doping phase diagram of cuprate superconductors
Lizardo H. C. M. Nunes, A. W. Teixeira, E. C. Marino
Starting from a spin-fermion model for the cuprate superconductors, we obtain an effective interaction for the charge carriers by integrating out the spin degrees of freedom. Our m…
Effective Potential for Emergent Majorana Fermions in Superconductor Systems
Allison W. Teixeira, Vagson. L. Carvalho-Santos, Jakson M. Fonseca
Majorana fermions cannot be found in nature as a free fundamental particle. Nevertheless, in condensed matter systems, they can emerge as a collective excitation. In this work, usi…
Analysis on the stability of in-surface magnetic configurations in toroidal nanoshells
A. W. Teixeira, S. Castillo-Sepúlveda, S. Vojkovic +4
Curvature of nanomagnets can be used to induce chiral textures in the magnetization field. Here we perform analytical calculations and micromagnetic simulations aiming to analyze t…
