Atomic frustrated impurity states in Weyl metals
(Amer Physical Soc, 2020-08-14)
We theoretically analyze the effect of the inversion symmetry breaking on the structure of the impurity molecular states in Weyl metals. We show that for the case of a highly noncentrosymmetric Weyl metallic host, the ...
Majorana molecules and their spectral fingerprints
(2020-08-15)
We introduce the concept of a Majorana molecule, a topological bound state appearing in the geometry of a double quantum dot structure flanking a topological superconducting nanowire. We demonstrate that, if the Majorana ...
Atomic frustrated impurity states in Weyl metals

We theoretically analyze the effect of the inversion symmetry breaking on the structure of the impurity molecular states in Weyl metals. We show that for the case of a highly noncentrosymmetric Weyl metallic host, the ...
Interaction induced hybridization of Majorana zero modes in a coupled quantum-dot-superconducting-nanowire hybrid system
(2020-10-05)
We study the low-energy transport properties of a hybrid device composed by a native quantum dot coupled to both ends of a topological superconducting nanowire section hosting Majorana zero modes. The account of the coupling ...
Catching the bound states in the continuum of a phantom atom in graphene
(2015-07-09)
We explore theoretically the formation of bound states in the continuum (BICs) in graphene hosting two collinear adatoms situated at different sides of the sheet and at the center of the hexagonal cell, where a phantom ...
Realization of anomalous multiferroicity in free-standing graphene with magnetic adatoms
(2016-01-01)
It is generally believed that free-standing graphene does not demonstrate any ferroic properties. In the present work we revise this statement and show that a single graphene sheet with a pair of magnetic adatoms can be ...
Antibonding ground state of adatom molecules in bulk Dirac semimetals
(2017-07-11)
The ground state of the diatomic molecules in nature is inevitably bonding, and its first excited state is antibonding. We demonstrate theoretically that, for a pair of distant adatoms placed buried in three-dimensional-Dirac ...
Tuning of heat and charge transport by Majorana fermions
(2018-12-01)
We investigate theoretically thermal and electrical conductances for the system consisting of a quantum dot (QD) connected both to a pair of Majorana fermions residing at the edges of a Kitaev wire and two metallic leads. ...
Spin-dependent beating patterns in thermoelectric properties: Filtering the carriers of the heat flux in a Kondo adatom system
(Amer Physical Soc, 2014-11-20)
We theoretically investigate the thermoelectric properties of a spin-polarized two-dimensional electron gas hosting a Kondo adatom hybridized with a STM tip. Such a setup is treated within the single-impurity Anderson model ...
Effect of inter-adatoms correlations on the local density of states of graphene
(Epl Association, European Physical Society, 2014-11-01)
We discuss theoretically the local density of states (LDOS) of a graphene sheet hosting two distant adatoms located at the center of hexagonal cells. By putting laterally a scanning tunneling microscope (STM) tip over a ...
