On the Noisy Road to Open Quantum Dynamics: The Place of Stochastic Hamiltonians
Pietro De Checchi, Federico Gallina, Barbara Fresch +1
Stochastic evolution underpins several approaches to the dynamics of open quantum systems, such as random modulation of Hamiltonian parameters, the stochastic Schrodinger equation…
Quantum trajectories and reduced dynamics in time-correlated environments
Pietro De Checchi, Federico Gallina, Barbara Fresch +1
The stochastic Schrödinger equation (SSE) provides a trajectory-level route to simulate the dynamics of open quantum systems with applications ranging from molecular processes to q…
Influence of excitonic coupling, static disorder, and coherent dynamics in action-2D electronic spectroscopy of a molecular dimer model
Matteo Bruschi, Roberto Zambon, Federico Gallina +1
We investigate the spectral features of Action-2D Electronic Spectroscopy (A-2DES) in a molecular dimer model across different regimes of excitonic coupling. By explicitly includin…
Simulating Non-Markovian Dynamics in Multidimensional Electronic Spectroscopy via Quantum Algorithm
Federico Gallina, Matteo Bruschi, Roberto Cacciari +1
Including the effect of the molecular environment in the numerical modeling of time-resolved electronic spectroscopy remains an important challenge in computational spectroscopy. I…
From Stochastic Hamiltonian to Quantum Simulation: Exploring Memory Effects in Exciton Dynamics
Federico Gallina, Matteo Bruschi, Barbara Fresch
The unraveling of open quantum system dynamics in terms of stochastic quantum trajectories offers a picture of open system dynamics that consistently considers memory effects stemm…
Strategies to simulate dephasing-assisted quantum transport on digital quantum computers
Federico Gallina, Matteo Bruschi, Barbara Fresch
Simulating charge and energy transfer in extended molecular networks requires an effective model to include the environment because it significantly affects the quantum dynamics. A…
Quantum computing for classical problems: Variational Quantum Eigensolver for activated processes
Pierpaolo Pravatto, Davide Castaldo, Federico Gallina +3
The theory of stochastic processes impacts both physical and social sciences. At the molecular scale, stochastic dynamics is ubiquitous because of thermal fluctuations. The Fokker-…
