Universal cooling of quantum systems via randomized measurements
Josias Langbehn, George Mouloudakis, Emma King +5
Designing cooling protocols is believed to require knowledge of the system spectrum. In contrast, cooling in nature occurs whenever the system is coupled to a cold bath. How does n…
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…
Entanglement instability in the interaction of two qubits with a common non-Markovian environment
G. Mouloudakis, P. Lambropoulos
In this work we study the steady state entanglement between two qubits interacting asymetrically with a common non-Markovian environment. Depending on the initial two-qubit state,…
Multi-photon enhancement of the Schwinger pair production mechanism under strong FEL radiation
G. Mouloudakis, P. Lambropoulos
In this work we study the production of electron-positron pairs from vacuum in presence of a field resulting from the collision of two counter-propagating FEL beams that undergo Ga…
Pairing superbunching with compounded non-linearity in a resonant transition
G. Mouloudakis, P. Lambropoulos
Through a quantitative analysis of an atomic transition driven strongly by quantized electromagnetic fields of various quantum states, we explore the role of quantum fluctuations o…
Revisiting photon-statistics effects on multiphoton ionization. II
G. Mouloudakis, P. Lambropoulos
In this paper, we extend the results of an earlier paper in which we had demonstrated the limitations of the notion of non-resonant multiphoton ionization, in the exploration of ph…
Effects of Field Fluctuations on Driven Autoionizing Resonances
G. Mouloudakis, P. Lambropoulos
The excitation of an autoionizing resonance by intense radiation requires a theoretical description beyond the transition probability per unit time. This implies a time-dependent f…
Autoionizing States driven by Stochastic Electromagnetic Fields
G. Mouloudakis, P. Lambropoulos
We have examined the profile of an isolated autoionizing resonance driven by a pulse of short duration and moderately strong field. The analysis has been based on stochastic differ…
