## š¬ Overview
A complete computational framework for cosmological perturbation theory with first-principles quantum corrections. This package implements:
- **Quantum-corrected Mukhanov-Sasaki equations** with backreaction from quantum fields
- **Full Boltzmann integration** with quantum scattering terms
- **Tensor perturbations** (gravitational waves) with quantum sources
- **Integration with CLASS/CAMB** for validation
- **Planck 2018 data validation** with Bayesian evidence computation
- **Production-ready pipeline** for cosmological parameter constraints
## š Features
### Core Physics
- **Quantum stress-energy perturbations** using Schwinger-Keldysh formalism
- **Bunch-Davies & Ī±-vacuum initial conditions** with quantum corrections
- **Renormalization schemes**: adiabatic (4th order), point-splitting, dimensional
- **Self-consistent backreaction** between metric and quantum fields
- **Entanglement entropy** calculations for cosmological horizons
### Numerical Methods
- Adaptive Runge-Kutta integration for perturbation equations
- Line-of-sight integration for CMB spectra
- Sparse matrix methods for large k-mode computations
- GPU acceleration support (via CuPy/Numba)
- Parallel computation over k-modes
### Data & Validation
- **Planck 2018 likelihood integration**
- **CMB power spectra** (TT, TE, EE, BB, ĻĻ) with quantum effects
- **Matter power spectrum** with quantum corrections
- **Bayesian evidence** calculation for model comparison
- **Hubble tension** and **Sā tension** analysis tools
## š¦ Installation
### Prerequisites
- Python 3.8 or higher
- C/C++ compiler (for CLASS integration)
- HDF5 library (for data storage)
