Asymptotics and zero behaviour of geometric polynomials
M. Bello-Hernández, M. Benito, Ã. Ciaurri +1
We obtain some results on the asymptotic behaviour of Geometric polynomials in both the complex plane minus and the interval . We also find the distance of consecu…
Escaping AB caging via Floquet engineering: photo-induced long-range interference in an all-band-flat model
Aamna Ahmed, Mónica Benito, Beatriz Pérez-González
Flat-band lattices hosting compact localized states are highly sensitive to external modulation, and the tailored design of a perturbation to imprint specific features becomes rele…
Readout of multi-level quantum geometry from electronic transport
Raffael L. Klees, Mónica Benito
The quantum geometric tensor (QGT) of a quantum system in a given parameter space captures both the geometry of the state manifold and the topology of the system. While the local Q…
Closed-Form Generators for Perturbative Transformations in Static and Periodically Driven Quantum Systems
Leander Reascos, Giovanni Francesco Diotallevi, Mónica Benito
We introduce a unified framework for the practical implementation of perturbative transformations that overcomes the limitations of existing construction methods. The central resul…
SymPT: a comprehensive tool for automating effective Hamiltonian derivations
Giovanni Francesco Diotallevi, Leander Reascos, Mónica Benito
The Schrieffer-Wolff transformation (SWT) is a foundational perturbative method for deriving effective Hamiltonians in quantum systems by systematically eliminating couplings betwe…
