Coulomb impurities in graphene driven by ultrashort electromagnetic pulses: Excitation, ionization, and pair creation
Saparboy Rakhmanov, Reinhold Egger, Davron Matrasulov
We provide a theory for electronic transitions induced by ultrashort electromagnetic pulses in two-dimensional artificial relativistic atoms which are created by a charged impurity…
Dispersive Drumhead States in Nodal-Line Semimetal Junctions
Francesco Buccheri, Reinhold Egger, Alessandro De Martino
We consider a smooth interface between a topological nodal-line semimetal and a topologically trivial insulator (e.g., the vacuum) or another semimetal with a nodal ring of differe…
Spin-Hall Current and Nonlocal Transport in Ferromagnet-Free Multi-band models for SrTiO3-Based Nanodevices in the presence of impurities
Domenico Giuliano, Andrea Nava, Carmine Antonio Perroni +3
We compute the spin-Hall conductance in a multiband model describing the two-dimensional electron gas formed at a LaAlO3/SrTiO3 interface in the presence of a finite concentration…
Dynamics of parafermionic states in transport measurements
Ida E. Nielsen, Jens Schulenborg, Reinhold Egger +1
Advances in hybrid fractional quantum Hall (FQH)-superconductor platforms pave the way for realisation of parafermionic modes. We analyse signatures of these non-abelian anyons in…
A quantum model of charge capture and release onto/from deep traps
Ivan I. Vrubel, Vasilii Khanin, Markus Suta +2
The rapid development of optical technologies and applications revealed the critical role of point defects affecting device performance. One of the powerful tools to study influenc…
