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.…
Unconventional Floquet topological phases in the SSH lattice
Dunkan Martínez, Yuriko Baba, Benjamín Santos +4
Topological materials, known for their edge states robust against local perturbations, hold promise for next-generation quantum technologies, but remain scarce in nature and challe…
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…
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…
