# DVR-jl
|
|
|
|
Solves the quantum $n$-body problem in finite volume (lattice) with periodic boundary conditions. Uses discrete variable representation (DVR) with optional support for complex scaling to study resonances. All details can be found in [H. Yu, N. Yapa, and S. König, Complex scaling in finite volume, Phys. Rev. C 109, 014316 (2024)](https://doi.org/10.1103/PhysRevC.109.014316).
|
|
|
|
Written in Julia with optional CUDA GPU acceleration (experimental).
|
|
|
|
## Installation
|
|
|
|
Make sure you have Julia installed. Required packages can be installed with a single command:
|
|
```bash
|
|
julia --project=. -e 'import Pkg; Pkg.instantiate()'
|
|
```
|
|
|
|
## Usage
|
|
|
|
See `calculations/3b_bound.jl` for an example on a 3-body bound state.
|
|
See `calculations/3b_res_from_paper.jl` for an example of a 3-body resonance via complex scaling.
|
|
|
|
## Planned features
|
|
|
|
- [ ] Spin and isospin degrees of freedom for nuclear calculations
|
|
- [ ] Multi-node HPC support
|
|
- [ ] Parity and cubic symmetries ($S_4$)
