Acoustic phonons, spin-phonon coupling and spin relaxation via the lattice reorientation mechanism in hexagonal germanium nanowires
Baksa Kolok, György Frank, András Pályi
Spin relaxation via electron-phonon interaction is an important decoherence mechanism for spin qubits. In this work, we study spin relaxation in hexagonal (2H) germanium, a novel d…
Stability of Weyl node merging processes under symmetry constraints
Gabriele Naselli, György Frank, Dániel Varjas +4
Changes in the number of Weyl nodes in Weyl semimetals occur through merging processes, usually involving a pair of oppositely charged nodes. More complicated processes involving m…
Classification and magic magnetic-field directions for spin-orbit-coupled double quantum dots
Aritra Sen, György Frank, Baksa Kolok +2
The spin of a single electron confined in a semiconductor quantum dot is a natural qubit candidate. Fundamental building blocks of spin-based quantum computing have been demonstrat…
Weyl points in ball-and-spring mechanical systems
Zoltán Guba, György Frank, Gergő Pintér +1
Degeneracy points of parameter-dependent Hermitian matrices play a fundamental role in quantum physics, as illustrated by the concept of Berry phase in quantum dynamics, the Weyl s…
Weyl-point teleportation
György Frank, Dániel Varjas, Gergő Pintér +1
In this work, we describe the phenomenon of Weyl-point teleportation. Weyl points usually move continuously in the configuration parameter space of a quantum system when the contro…
Topological charge distributions of an interacting two-spin system
György Frank, Dániel Varjas, Péter Vrana +2
Quantum systems are often described by parameter-dependent Hamiltonians. Points in parameter space where two levels are degenerate can carry a topological charge. Here we theoretic…
