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…
Hybrid quantum-classical simulation of quantum speed limits in open quantum systems
Junjie Liu, Dvira Segal, Gabriel Hanna
The quantum speed limit (QSL) provides a fundamental upper bound on the speed of quantum evolution, but its evaluation in generic open quantum systems still presents a formidable c…
Heat transfer statistics in mixed quantum-classical systems
Junjie Liu, Chang-Yu Hsieh, Dvira Segal +1
The modelling of quantum heat transfer processes at the nanoscale is crucial for the development of energy harvesting and molecular electronics devices. Herein, we adopt a mixed qu…
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…
Efficient and Deterministic Propagation of Mixed Quantum-Classical Liouville Dynamics
Junjie Liu, Gabriel Hanna
We propose a highly efficient mixed quantum-classical molecular dynamics scheme based on a solution of the quantum-classical Liouville equation (QCLE). By casting the equations of…
Energetics and structural properties of three-dimensional bosonic clusters near threshold
G. J. Hanna, D. Blume
We treat three-dimensional bosonic clusters wih up to N=40 atoms, interacting additively through two-body Van der Waals potentials, in the near-threshold regime. Our study inludes…
