Symmetry-induced even/odd parity in charge and heat pumping
Miguel A. N. Araújo, Pedro Ninhos, Pedro Ribeiro
It is shown that the presence of discrete symmetries in Floquet systems connected to metallic reservoirs imprints a definite parity on the charge and heat pumping as a function of…
Broken-symmetry phases of interacting nested Weyl and Dirac loops
Miguel A. N. Araújo, Linhu Li
We study interaction-induced broken symmetry phases that can arise in metallic or semimetallic band structures with two nested Weyl or Dirac loops. The odered phases can be of the…
Engineering topological phases with a three-dimensional nodal-loop semimetal
Linhu Li, Han Hoe Yap, Miguel A. N. Araújo +1
A three-dimensional (3D) nodal-loop semimetal phase is exploited to engineer a number of intriguing phases featuring different peculiar topological surface states. In particular, b…
Andreev spectroscopy of Majorana states in topological superconductors with multipocket Fermi surfaces
Ana C. Silva, Miguel A. N. Araújo, Pedro D. Sacramento
The topological properties of a multiband topological superconductor in two dimensions are studied, when the latter is obtained by introducing electron pairing in an otherwise topo…
Change of an insulator's topological properties by a Hubbard interaction
Miguel A. N. Araújo, Eduardo V. Castro, Pedro D. Sacramento
We introduce two dimensional fermionic band models with two orbitals per lattice site, or one spinful orbital, and which have a non-zero topological Chern number that can be change…
