Electronic interactions in a vacancy-engineered honeycomb lattice: Transition from a nodal-line semimetal to a magnetic insulator
Andressa R. Medeiros-Silva, Mariana Malard, Rodrigo G. Pereira +1
Nodal-line semimetals (NLSMs) harbor a variety of novel physical properties owing to the particularities of the band degeneracies that characterize the spectrum of these materials.…
Detecting and leaking a Majorana bound state through proximity to a Kitaev ring
Mariana Malard, David S. Brandão
We show that the existence of a Majorana bound state at one end of a Kitaev chain is unambiguously signaled by observable quantities in a nearby Kitaev ring. When the Kitaev chain…
Symmetry-enforced nodal lines in the band structures of vacancy-engineered graphene
Matheus S. M. de Sousa, Fujun Liu, Mariana Malard +2
We elaborate that single-layer graphene with periodic vacancies can have a band structure containing nodal lines or nodal loops, opening the possibility of graphene-based electroni…
Less is more: Vacancy-engineered nodal-line semimetals
Fujun Liu, Fanyao Qu, Igor Zutic +1
A nodal-line semimetal phase which is enforced by the symmetries of the material is interesting from fundamental and application standpoints. We demonstrate that such a phase of ma…
Scaling behavior in a multicritical one-dimensional topological insulator
M. Malard, H. Johannesson, W. Chen
A class of Aubry-André-Harper models of spin-orbit coupled electrons exhibits a topological phase diagram where two regions belonging to the same phase are split up by a multicriti…
Multicriticality in a one-dimensional topological band insulator
Mariana Malard, David Brandao, Paulo Eduardo de Brito +1
A central tenet in the theory of quantum phase transitions (QPTs) is that a nonanalyticity in the ground-state energy in the thermodynamic limit implies a QPT. Here we report on a…
