Shuttling of parafermions in an electronic ladder model
Botond Osváth, Gergely Barcza, László Oroszlány
Parafermions with non-Abelian statistics have been proposed as a promising platform for quantum computation, potentially enabling a broader set of topologically protected gates tha…

AKLT Hamiltonian from Hubbard tripods
Claire Benjamin, Dániel Varjas, Gábor Széchenyi +2
We investigate how the spin-1 Affleck-Kennedy-Lieb-Tasaki (AKLT) Hamiltonian can emerge from a microscopic fermionic model based on half-filled Hubbard tripods. We first show that…

Non-unitary Time Evolution via the Chebyshev Expansion Method
Áron Holló, Dániel Varjas, Cosma Fulga +2
The Chebyshev expansion method is a well-established technique for computing the time evolution of quantum states, particularly in Hermitian systems with a bounded spectrum. Here,…
