Evolution of a Non-Hermitian Quantum Single-Molecule Junction at Constant Temperature
Andrea Grimaldi, Alessandro Sergi, Antonino Messina
This work concerns the theoretical description of the quantum dynamics of molecular junctions with thermal fluctuations and probability losses To this end, we propose a theory for…
Two-qubit entanglement generation through non-Hermitian Hamiltonians induced by repeated measurements on an ancilla
R. Grimaudo, A. Messina, A. Sergi +2
In contrast to classical systems, actual implementation of non-Hermitian Hamiltonian dynamics for quantum systems is a challenge because the processes of energy gain and dissipatio…
Proposal of a computational approach for simulating thermal bosonic fields in phase space
Alessandro Sergi, Roberto Grimaudo, Gabriel Hanna +1
When a quantum field is in contact with a thermal bath, the vacuum state of the field may be generalized to a thermal vacuum state, which takes into account the thermal noise. In t…
Clusterization of weakly-interacting bosons in one dimension: an analytic study at zero temperature
S. Prestipino, A. Sergi, E. Bruno
We study a system of penetrable bosons on a line, focusing on the high-density/weak-interaction regime, where the ground state is, to a good approximation, a condensate. Under comp…
Quasi-Lie Brackets and the Breaking of Time-Translation Symmetry for Quantum Systems Embedded in Classical Baths
Alessandro Sergi, Gabriel Hanna, Roberto Grimaudo +1
Many open quantum systems encountered in both natural and synthetic situations are embedded in classical-like baths. Often, the bath degrees of freedom may be represented in terms…
