Tunneling spectroscopy of the spinon-Kondo effect in one-dimensional Mott insulators
Rodrigo G. Pereira, Bruno F. Marquez, Karen Hallberg +2
We study the tunneling density of states (TDOS) in one-dimensional Mott insulators at energies below the charge gap. By employing nonlinear Luttinger liquid theory and density-matr…
Local spin-flip transitions induced by magnetic quantum impurities in two-dimensional magnets
Tim Bauer, Lucas R. D. Freitas, Eric C. Andrade +2
We predict a general local spin-flip transition mechanism caused by magnetic quantum impurities in (partially) polarized phases of quantum magnets in the absence of conservation la…
Electric polarization near vortices in the extended Kitaev model
Lucas R. D. Freitas, Tim Bauer, Reinhold Egger +1
We formulate a Majorana mean-field theory for the extended Kitaev model in a magnetic Zeeman field of arbitrary direction, and apply it for studying spatially inhomogeneous s…
Tunable breakdown of the polaron picture for mobile impurities in a topological semimetal
M. A. Caracanhas, R. G. Pereira
Mobile impurities in cold atomic gases constitute a new platform for investigating polaron physics. Here we show that when impurity atoms interact with a two-dimensional Fermi gas…
Mobile Impurities and Orthogonality Catastrophe in two-dimensional Vortex Lattices
M. A. Caracanhas, R. G. Pereira
We investigate the properties of a neutral impurity atom coupled with the Tkachenko modes of a two-dimensional vortex lattice Bose-Einstein condensate. In contrast with polarons in…
Tkachenko polarons in vortex lattices
M. A. Caracanhas, V. S. Bagnato, R. G. Pereira
We analyze the properties of impurities immersed in a vortex lattice formed by ultracold bosons in the mean field quantum Hall regime. In addition to the effects of a periodic latt…
