QuDPy-FDGF: A Python-Based Tool for Computing Ultrafast Nonlinear Optical Responses Using Frequency Domain Green's Functions
Mathieu Desmarais, Simón Paiva-Ortega, Félix Brunell +3
We present QuDPy-FDGF, an open-source Python framework that evaluates Liouville-space pathways as hybrid chains of time propagators and frequency-domain Green's functions. Frequenc…
Bottom-Up Design of Quantum Optical Experiments Using Discrete Generative Models
Isaac L. Huidobro-Meezs, Simón Paiva-Ortega, Rodrigo A. Vargas-Hernández
Designing quantum optical experiments requires searching over discrete circuit topologies and continuous parameters, often with multiple realizations of the same target state. Grap…
SAKE: Spectral Autodiff Kernel Expansion for Geometric Liouvillian Transport. A Differential-Geometric Framework for Response Transport in Quantum Dynamical Systems
Eric R. Bittner, Carlos Silva-Acuna, Hao Li +1
We introduce the Spectral Autodiff Kernel Expansion (SAKE), a differentiable computational framework for transporting nonlinear spectroscopic response between neighboring quantum d…
Detection Defines Dephasing in Two-Dimensional Electronic Spectroscopy of Materials: Coherent Field Emission versus Incoherent Population Observables
Simón Paiva-Ortega, Hao Li, Eric R. Bittner +1
The homogeneous spectral linewidth associated with light-matter interactions is a fundamental descriptor of the optical properties of materials, governed by the quantum dynamics of…
