Unconventional superconductivity in altermagnets with spin-orbit coupling
Vanuildo S. de Carvalho, Hermann Freire
We investigate some possible symmetries of the superconducting state that emerges in three-dimensional altermagnets in the presence of spin-orbit coupling. We demonstrate within a…
Odd-frequency pair density wave in the Kitaev-Kondo lattice model
Vanuildo S. de Carvalho, Rafael M. P. Teixeira, Hermann Freire +1
We investigate the properties of the Kitaev-Kondo lattice model defined on a bilayer honeycomb lattice by means of the SO(3) Majorana representation for spin- moments. We firs…
Thermodynamic signatures of an antiferromagnetic quantum critical point inside a superconducting dome
Vanuildo S. de Carvalho, Andrey V. Chubukov, Rafael M. Fernandes
Recent experiments in unconventional superconductors, and in particular iron-based materials, have reported evidence of an antiferromagnetic quantum critical point (AFM-QCP) emergi…
Quadrupolar spin liquid, octupolar Kondo coupling and odd-frequency superconductivity in an exactly solvable model
Carlene S. de Farias, Vanuildo S. de Carvalho, Eduardo Miranda +1
We propose an exactly solvable model for local moments on the honeycomb lattice. Our construction is guided by a symmetry analysis and by the requirement o…
DC resistivity near a nematic quantum critical point: Effects of weak disorder and acoustic phonons
Lucas E. Vieira, Vanuildo S. de Carvalho, Hermann Freire
We calculate the resistivity associated with an Ising-nematic quantum critical point in the presence of disorder and acoustic phonons in the lattice model. We use the memory-matrix…
Resistivity near a nematic quantum critical point: Impact of acoustic phonons
V. S. de Carvalho, R. M. Fernandes
We revisit the issue of the resistivity of a two-dimensional electronic system tuned to a nematic quantum critical point (QCP), focusing on the non-trivial impact of the coupling t…
