Valley to charge current conversion in graphene grain boundaries
Francesco Romeo
The conduction properties of a grain boundary junction with Fermi velocity mismatch are analyzed. We provide a generalization of the Dirac Hamiltonian model taking into account the…
Topological phases of a Kitaev tie
Alfonso Maiellaro, Francesco Romeo, Roberta Citro
We investigate the topological properties of a Kitaev chain in the shape of a legged-ring, which is here referred to as Kitaev tie. We demonstrate that the Kitaev tie is a frustrat…
Conduction properties of extended defect states in Dirac materials
Francesco Romeo
We demonstrate the existence of localized states in close vicinity of a linear defect in graphene. These states have insulating or conducting character. Insulating states form a fl…
Unveiling Signatures of Topological Phases in Open Kitaev Chains and Ladders
Alfonso Maiellaro, Francesco Romeo, Carmine Antonio Perroni +2
In this work, the general problem of the characterization of the topological phase of an open quantum system is addressed. In particular, we study the topological properties of Kit…
Search for supersymmetry in final states with photons and missing transverse momentum in proton-proton collisions at 13 TeV
CMS Collaboration
Results are reported for a search for supersymmetry in final states with photons and missing transverse momentum in proton-proton collisions at the LHC. The data sample corresponds…
