The non-Hermitian landscape of autoionization
G. Mouloudakis, P. Lambropoulos
We report on the existence of exceptional points (EPs) in single-resonance autoionization and provide analytical expressions for their positions in parameter space, in terms of the…
Non-Markovianity in the time evolution of open quantum systems assessed by means of quantum state distance
G. Mouloudakis, I. Stergou, P. Lambropoulos
We provide a quantitative evaluation of non-Markovianity (NM) for an XX chain of interacting qubits with one end coupled to a reservoir. The NM of several non-Markovian spectral de…
Coalescence of non-Markovian dissipation, quantum Zeno effect and non-Hermitian physics, in a simple realistic quantum system
G. Mouloudakis, P. Lambropoulos
Diagonalization of the effective Hamiltonian describing an open quantum system is the usual method of tracking its exceptional points. Although, such a method is successful for tra…
Arbitrary length XX spin chains boundary-driven by non-Markovian environments
G. Mouloudakis, T. Ilias, P. Lambropoulos
In this work we provide a recursive method of calculating the wavefunction of a XX spin chain coupled at both ends to non-Markovian reservoirs with arbitrary spectral density. The…
Route to Direct Multiphoton Multiple Ionization
P. Lambropoulos, G. M. Nikolopoulos, K. G. Papamihail
We address the concept of direct multiphoton multiple ionization in atoms exposed to intense, short wavelength radiation and explore the conditions under which such processes domin…
Time-dependent calculation of ionization in Potassium at mid-infrared wavelengths
P. Maragakis, E. Cormier, P. Lambropoulos
We study the dynamics of the Potassium atom in the mid-infrared, high intensity, short laser pulse regime. We ascertain numerical convergence by comparing the results obtained by t…
