Kibble-Zurek behavior in disordered Chern insulators
Lara Ulčakar, Jernej Mravlje, Tomaž Rejec
Even though no local order parameter in the sense of the Landau theory exists for topological quantum phase transitions in Chern insulators, the highly non-local Berry curvature ex…
Thermal effects on a nonadiabatic spin-flip protocol of spin-orbit qubits
Brecht Donvil, Lara Ulčakar, Tomaž Rejec +1
We study the influence of a thermal environment on a non-adiabatic spin-flip driving protocol of spin-orbit qubits. The driving protocol operates by moving the qubit, trapped in a…
Slow quenches in Chern insulator ribbons
Lara Ulčakar, Jernej Mravlje, Tomaž Rejec
We investigate slow quenches in Chern insulators in ribbon geometry. We consider the Qi-Wu-Zhang model and slowly ramp the parameters (large time of the quench ) from a non-topo…
On the resilience of magic number theory for conductance ratios of aromatic molecules
Lara Ulčakar, Tomaž Rejec, Jure Kokalj +5
If simple guidelines could be established for understanding how quantum interference (QI) can be exploited to control the flow of electricity through single molecules, then new fun…
