Memory preservation and cooperative shielding in complex quantum networks
Simone Ausilio, Fausto Borgonovi, Giuseppe Luca Celardo +2
Complex quantum networks are powerful tools in the modeling of transport phenomena, particularly for biological systems, and enable the study of emergent phenomena in many-body qua…
Bio-inspired natural sunlight-pumped lasers
Francesco Mattiotti, William M. Brown, Nicola Piovella +3
Even though sunlight is by far the most abundant renewable energy source available to humanity, its dilute and variable nature has kept efficient ways to collect, store, and distri…
Open quantum systems decay across time
Juliane Klatt, Chahan Michael Kropf, Stefan Yoshi Buhmann
The description of an open quantum system's decay almost always requires several approximations as to remain tractable. Here, we first revisit the meaning, domain and seeming contr…
Protecting quantum coherences from static noise and disorder
Chahan M. Kropf
Quantum coherences are paramount resources for applications, such as quantum-enhanced light-harvesting or quantum computing, which are fragile against environmental noise. We here…
Electric-field assisted optimal quantum transport of photo-excitations in polar heterostructures
Chahan M. Kropf, G. Luca Celardo, Claudio Giannetti +1
Transition-metal-oxide (TMO) heterostructures are promising candidates for building photon-harvesting devices which can exploit optimal quantum transport of charge excitations gene…

Chahan M. Kropf, Angelo Valli, Paolo Franceschini +4
The possibility to exploit quantum coherence to strongly enhance the efficiency of charge transport in solid state devices working at ambient conditions would pave the way to disru…
Preserving Measurements for Optimal State Discrimination over Quantum Channels
Spiros Kechrimparis, Tanmay Singal, Chahan M. Kropf +1
In this work, we consider optimal state discrimination for a quantum system that interacts with an environment, i.e., states evolve under a quantum channel. We show the conditions…
Temperature of a single chaotic eigenstate
Fausto Borgonovi, Francesco Mattiotti, Felix M. Izrailev
The onset of thermalization in a closed finite system of randomly interacting bosons, at the level of a single eigenstate, is discussed. The main interest is in the emergence of th…
Cooperative shielding in many-body systems with long-range interaction
Lea F. Santos, Fausto Borgonovi, Giuseppe Luca Celardo
In recent experiments with ion traps, long-range interactions were associated with the exceptionally fast propagation of perturbation, while in some theoretical works they have als…
A Quantum Biological Switch Based on Superradiance Transitions
D. Ferrari, G. L. Celardo, G. P. Berman +2
A linear chain of connected electron sites with two asymmetric sinks, one attached to each end, is used as a simple model of quantum electron transfer in photosynthetic bio-complex…
Chaos and statistical relaxation in quantum systems of interacting particles
L. F. Santos, F. Borgonovi, F. M. Izrailev
We propose a method to study the transition to chaos in isolated quantum systems of interacting particles. It is based on the concept of delocalization of eigenstates in the energy…

When a quantum nonlinear system is linearly coupled to an infinite bath of harmonic oscillators, quantum coherence of the system is lost on a decoherence time-scale . Neverthe…
