Quantum trajectories and reduced dynamics in time-correlated environments

Pietro De Checchi, Federico Gallina, Barbara Fresch, Giulio G. Giusteri

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 quantum technologies. We study a colored-noise extension of the SSE based on an Ornstein-Uhlenbeck (OU) noise drive and …

On the Noisy Road to Open Quantum Dynamics: The Place of Stochastic Hamiltonians

Pietro De Checchi, Federico Gallina, Barbara Fresch, Giulio G. Giusteri

ABSTRACT Stochastic evolution underpins several approaches to the dynamics of open quantum systems, such as random modulation of Hamiltonian parameters, the stochastic Schrödinger equation (SSE), and the stochastic Liouville equation (SLE). These approaches replace the explicit system–environment coupling with an effective system‐only …

Stimuli‐Responsive Photoacid Polyelectrolytes

Carlo Gericke, Edmondo Maria Benetti, Barbara Fresch, Cristian Pezzato

Spiropyran-based polymers are widely studied on account of their multifaceted stimuli-responsive behaviors. However, their photoacid characteristics in aqueous environments remain overlooked. Here, we synthesized a series of poly(3-sulfopropyl methacrylate) copolymers containing spiropyran units in their photoacidic, protonated merocyanine form. We studied the …

Nanohybridization as a Route to a Water-Friendly Therapeutic Tool for Rescuing Misfolded Proteins

Mary Bortoluzzi, Aura Cencini, Lavinia Rutigliano, Graziano Rilievo et autres

High Resolution Image Download MS PowerPoint Slide Misfolded proteins cause several threatening pathologies, ranging from Alzheimer’s disease to cystic fibrosis. Although several protein folding correctors were tested, their delivery is usually inadequate. Here, via a self-assembly wet reaction, colloidal γ-Fe 2 O …

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, Barbara Fresch

We investigate the spectral features of Action-2D Electronic Spectroscopy (A-2DES) using a molecular dimer model across different regimes of excitonic coupling. By explicitly including a second-excited state for each chromophore, we simulate A-2DES spectra ranging from the non-interacting limit to the strong-coupling …
