Excitons in twisted AA' hexagonal boron nitride bilayers
Pedro Roman-Taboada, Estefania Obregon-Castillo, Andrés R. Botello-Mendez +1
The twisted hexagonal boron nitride (hBN) bilayer has demonstrated exceptional properties, particularly the existence of electronic flat bands without needing a magic angle, sugges…
Method for finding the exact effective Hamiltonian of time driven quantum systems
J. C. Sandoval-Santana, V. G. Ibarra-Sierra, J. L. Cardoso +3
Time-driven quantum systems are important in many different fields of physics like cold atoms, solid state, optics, etc. Many of their properties are encoded in the time evolution…
Landauer-Büttiker conductivity for spatially-dependent uniaxial strained armchair-terminated graphene nanoribbons
Abdiel E. Champo, Pedro Roman-Taboada, Gerardo G. Naumis
The Landauer-Büttiker conductivity of arbitrary uniaxial spatially dependent strain in an armchair graphene nanoribbon is studied. Due to the uniaxial character of the strain, the…
Topological phase-diagram of time-periodically rippled zigzag graphene nanoribbons
Pedro Roman-Taboada, Gerardo G. Naumis
The topological properties of electronic edge states in time-periodically driven spatially-periodic corrugated zigzag graphene nanoribbons are studied. An effective one-dimensional…
Topological edge states on time-periodically strained armchair graphene nanoribbons
Pedro Roman-Taboada, Gerardo G. Naumis
We report the emergence of electronic edge states in time-periodically driven strained armchair terminated graphene nanoribbons. This is done by considering a short-pulse spatial-p…
Topological flat bands in time-periodically driven uniaxial strained graphene nanoribbons
Pedro Roman-Taboada, Gerardo G. Naumis
We study the emergence of electronic non-trivial topological flat bands in time-periodically driven strained graphene within a tight binding approach based on the Floquet formalism…
Spectral butterfly and electronic localization in rippled-graphene nanorribons: mapping onto effective one-dimensional chains
Pedro Roman-Taboada, Gerardo G. Naumis
We report an exact map into one dimensional effective chains, of the tight-binding Hamiltonian for electrons in armchair and zigzag graphene nanoribbons with any uniaxial ripple. T…
Spectral butterfly, mixed Dirac-Schrödinger fermion behavior and topological states in armchair uniaxial strained graphene
Pedro Roman-Taboada, Gerardo G. Naumis
An exact mapping of the tight-binding Hamiltonian for a graphene's nanoribbon under any armchair uniaxial strain into an effective one-dimensional system is presented. As an applic…
Mapping of strained graphene into one-dimensional Hamiltonians: quasicrystals and modulated crystals
Gerardo G. Naumis, Pedro Roman-Taboada
The electronic properties of graphene under any arbitrary uniaxial strain field are obtained by an exact mapping of the corresponding tight-binding Hamiltonian into an effective on…
