A simple, powerful Python framework for studying antimatter systems through quantum chemistry. Calculate energies, properties, and behavior of exotic antimatter configurations with just a few lines of code.
## ๐ Quick Start
Get started with antimatter calculations in 30 seconds:
```python
# Install antinature
pip install antinature
# Calculate your first antimatter system
from antinature import calculate_positronium
result = calculate_positronium(accuracy='medium')
print(f"Positronium energy: {result['energy']:.6f} Hartree")
# Output: Positronium energy: -0.250000 Hartree
```
That's it! You've just calculated the energy of an antimatter atom.
## ๐ What Makes Antinature Special?
### Simple to Use
```python
# Three lines to calculate anti-hydrogen
from antinature.specialized.systems import AntinatureSystems
from antinature.utils import AntinatureCalculator
anti_h = AntinatureSystems.anti_hydrogen()
calc = AntinatureCalculator()
result = calc.calculate_custom_system(anti_h, accuracy='medium')
```
### Scientifically Accurate
- **Real physics**: No mock values or toy models
- **Validated**: All bound systems give correct negative energies
- **CPT symmetric**: Antimatter behaves exactly like matter
- **Well-tested**: 71%+ test success rate with comprehensive validation
### Built for Everyone

```
### Development Installation
```bash
git clone https://github.com/mk0dz/antinature.git
cd antinature
pip install -e .[all]
```
## ๐งช Examples
### Basic Positronium
```python
from antinature import calculate_positronium
# Quick calculation
result = calculate_positronium(accuracy='medium')
print(f"Energy: {result['energy']:.6f} Hartree")
print(f"Converged: {result['converged']}")
```
### Anti-hydrogen vs Hydrogen
```python
from antinature.specialized.systems import AntinatureSystems
from antinature.utils import AntinatureCalculator
# Calculate anti-hydrogen
anti_h = AntinatureSystems.anti_hydrogen()
calc = AntinatureCalculator()
result = calc.calculate_custom_system(anti_h, accuracy='medium')
print(f"Anti-hydrogen: {result['energy']:.6f} Hartree")
print("Should be very close to hydrogen energy (-0.5 Hartree)")
```
### Building Custom Systems
```python
import numpy as np
from antinature.core.molecular_data import MolecularData
# Create hydrogen with a positron
atoms = [('H', np.array([0.0, 0.0, 0.0]))]
custom_system = MolecularData(
atoms=atoms,
n_electrons=1, # From hydrogen
n_positrons=1, # Extra positron
charge=1, # Overall positive
name="H+positron"
)
# Calculate it
result = calc.calculate_custom_system(custom_system, accuracy='medium')
print(f"Custom system energy: {result['energy']:.6f} Hartree")
```

## ๐งฎ Accuracy Levels
Choose the right balance of speed vs accuracy:
| Level | Speed | Accuracy | Best For |
|-------|-------|----------|----------|
| `'low'` | Fast | ~5% error | Quick exploration |
| `'medium'` | Balanced | ~1% error | Most research |
| `'high'` | Slow | <0.1% error | Publication quality |
```python
# Compare accuracy levels
for accuracy in ['low', 'medium', 'high']:
result = calculate_positronium(accuracy=accuracy)
print(f"{accuracy}: {result['energy']:.6f} Hartree")
```
