Topological transition from nodal to nodeless Zeeman splitting in altermagnets
Rafael M. Fernandes, Vanuildo S. de Carvalho, Turan Birol +1
In an altermagnet, the symmetry that relates configurations with flipped magnetic moments is a rotation. This makes it qualitatively different from a ferromagnet, where no such sym…
Multipolar spin liquid in an exactly solvable model for moments
Vanuildo S. de Carvalho, Hermann Freire, Rodrigo G. Pereira
We study an exactly solvable model with bond-directional quadrupolar and octupolar interactions between spin-orbital entangled moments on the honey…
Network construction of non-Abelian chiral spin liquids
Hernan B. Xavier, Claudio Chamon, Rodrigo G. Pereira
We use a network of chiral junctions to construct a family of topological chiral spin liquids in two spatial dimensions. The chiral spin liquid phase harbors SU(2) anyons, whic…
Quench dynamics of the Kondo effect: transport across an impurity coupled to interacting wires
Moallison F. Cavalcante, Rodrigo G. Pereira, Maria C. O. Aguiar
We study the real-time dynamics of the Kondo effect after a quantum quench in which a magnetic impurity is coupled to two metallic Hubbard chains. Using an effective field theory a…
Boundary Modes in the Chamon Model
Weslei B. Fontana, Rodrigo G. Pereira
We study the fracton phase described by the Chamon model in a manifold with a boundary. The new processes and excitations emerging at the boundary can be understood by means of a d…
Scanning tunneling spectroscopy of Majorana zero modes in a Kitaev spin liquid
Tim Bauer, Lucas R. D. Freitas, Rodrigo G. Pereira +1
We describe scanning tunneling spectroscopic signatures of Majorana zero modes (MZMs) in Kitaev spin liquids. The tunnel conductance is determined by the dynamical spin correlation…
