Fibonacci Waveguide Quantum Electrodynamics
Florian Bönsel, Flore K. Kunst, Federico Roccati
Waveguide quantum electrodynamics (QED) provides a powerful framework for engineering quantum interactions, traditionally relying on periodic photonic arrays with continuous energy…
Controlling Markovianity with Chiral Giant Atoms
Federico Roccati, Dario Cilluffo
Giant artificial atoms are promising and flexible building blocks for the implementation of analog quantum simulators. They are realized via a multi-local pattern of couplings of t…
Quantum correlations in dissipative gain-loss systems across exceptional points
Federico Roccati, Archak Purkayastha, G. Massimo Palma +1
We investigate the behavior of correlations dynamics in a dissipative gain-loss system. First, we consider a setup made of two coupled lossy oscillators, with one of them subject t…
Non-Hermitian Hamiltonian Deformations in Quantum Mechanics
Apollonas S. Matsoukas-Roubeas, Federico Roccati, Julien Cornelius +3
The construction of exactly-solvable models has recently been advanced by considering integrable deformations and related Hamiltonian deformations in quantum mechanics.…
Non-Hermitian skin effect as an impurity problem
Federico Roccati
A striking feature of non-Hermitian tight-binding Hamiltonians is the high sensitivity of both spectrum and eigenstates to boundary conditions. Indeed, if the spectrum under period…
Modeling epidemics through ladder operators
F. Bagarello, F. Gargano, F. Roccati
We propose a simple model of spreading of some infection in an originally healthy population which is different from other models existing in the literature. In particular, we use…
Reply to Comment on "A no-go result for the quantum damped harmonic oscillator"
F. Bagarello, F. Gargano, F. Roccati
In a recent paper, \cite{deguchi}, Deguchi and Fujiwara claim that our results in \cite{BGR} are wrong, and compute what they claim is the square integrable vacuum of their annihil…
Tridiagonality, supersymmetry and non self-adjoint Hamiltonians
F. Bagarello, F. Gargano, F. Roccati
In this paper we consider some aspects of tridiagonal, non self-adjoint, Hamiltonians and of their supersymmetric counterparts. In particular, the problem of factorization is discu…
A no-go result for the quantum damped harmonic oscillator
Fabio Bagarello, Francesco Gargano, Federico Roccati
In this letter we show that it is not possible to set up a canonical quantization for the damped harmonic oscillator using the Bateman lagrangian. In particular, we prove that no s…
