description: A Real-time Instanton Approach to Quantum Activation

Description

This archive contains the complete computational repository for the research paper "A Real-time Instanton Approach to Quantum Activation" (arXiv:2409.00681), including all source code, documentation, and computational data files required for full reproducibility.

Contents

Source Code & Documentation:



Python package (src/metastable/) implementing the Keldysh field theory approach

Interactive documentation and derivations (docs/)

Visualization scripts for all figures

Test suite and configuration files


Computational Data Files (1.9 GB):



docs/fixed_points/examples/map.npz (12 MB) - Basic fixed point map data

docs/fixed_points/examples/map-with-stability.npz (233 MB) - Fixed points with stability analysis

docs/paths/sweeps/kappa/sweep/map.npz (735 MB) - Kappa parameter sweep results

docs/paths/sweeps/epsilon/sweep/map.npz (917 MB) - Epsilon parameter sweep results


Research Context

This work investigates quantum activation in driven dissipative systems far from equilibrium, focusing on how quantum noise associated with relaxation can lead to transitions between metastable states, even at zero temperature. The repository provides:



Theoretical Framework: Complete derivation of the Keldysh Lagrangian and auxiliary Hamiltonian formulation

Computational Methods: Implementation of fixed-point analysis and stability calculations

Parameter Studies: Comprehensive sweeps of system parameters (κ and ε)

Visualization Tools: Scripts to reproduce all figures in the publication


Usage Instructions



Extract Archive: unzip metastable-complete-with-data.zip

Install Dependencies: pip install -e . (requires Python ≥3.10)

Run Examples: Navigate to docs/fixed_points/examples/ or docs/paths/sweeps/

View Documentation: Open docs/index.md or visit the live documentation


Key Features



Fixed Point Analysis: Calculation and classification of system fixed points in the bistable regime

Stability Analysis: Eigenvalue analysis of the Jacobian at fixed points

Path Integration: Implementation of switching trajectory calculations

Interactive Visualizations: Plotly-based interactive plots for exploration
