Emergent Quantum Geometric Phases in Holey Graphene
Pablo Canteli, Yuriko Baba, Juan Salvador-Sánchez +11
In graphene and other two-dimensional materials, periodic modulations of the electron density can significantly alter the energy spectrum and transport properties. Here, we report…
Multiple chiral Majorana states in proximitized magnetic topological insulator heterostructures
Alejandro S. Gómez, Rafael A. Molina, Pablo Burset +1
Achieving robust topological superconductivity with multiple Majorana channels is a key step for scalable topological quantum computing. To this end, we investigate magnetically do…
Many-body quantum chaos in excitonic spectra from first principles
Daniel Hernangómez-Pérez, Rafael A. Molina
We demonstrate that realistic excitonic many-body Hamiltonians obtained from first-principles GW-Bethe-Salpeter equation calculations can exhibit quantum chaos governed by random-m…
Cubic edge dispersion in a semi-Dirac Chern insulator
Marta García Olmos, David Martín Tejedor, Mario Amado +2
Topological edge states in Chern insulators are typically characterized by a linear dispersion relation inherited from the Dirac structure of the bulk Hamiltonian. Here we show tha…
Corner Majorana states in semi-Dirac materials
M. García Olmos, Y. Baba, R. A. Molina +1
Proximity-induced superconductivity in low-dimensional systems offers a powerful pathway to engineer topological superconducting phases in, otherwise, non-superconducting systems.…
Tunable plasmon modes and topological transitions in single- and bilayer semi-Dirac materials
Debasmita Giri, John Schliemann, Rafael Molina +1
We investigate the plasmonic response of single- and bilayer semi-Dirac materials under the influence of a tunable parameter that governs topological transitions via Dirac cone…
Spin-dependent transport through edge states in 2D semi-Dirac materials with Rashba spin-orbit coupling and band inversion
Marta García-Olmos, Yuriko Baba, Alexander López +2
We investigate the bulk-boundary correspondence in two-dimensional type-I semi-Dirac materials with band inversion and Rashba spin-orbit coupling. Employing a dimensional reduction…
Monolayer transition metal dichalcogenides under finite-pulse polarized radiation
Alejandro S. Gómez, Yuriko Baba, Francisco Domínguez-Adame +1
Recent advances in time-resolved angle-resolved photoemission spectroscopy have enabled access to ultrafast electron states and their spin dynamics in solids. Atomically thin trans…
Radiation-induced dynamical formation of Floquet-Bloch bands in Dirac Hamiltonians
Yuriko Baba, Vanessa Junk, Wolfgang Hogger +3
Recent experiments, combing ultrafast strong-field irradiation of surfaces with time- and angle-resolved photoemission spectroscopy, allow for monitoring the time-dependent charge…
High order momentum topological insulator in 2D semi-Dirac materials
Marta García Olmos, Yuriko Baba, Mario Amado +1
Semi-Dirac materials in 2D present an anisotropic dispersion relation, linear along one direction and quadratic along the perpendicular one. This study explores the topological pro…
