# 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).

## Installation
|
|
|
|
Make sure you have Julia installed. To install the required packages, follow these steps:
|
|
|
|
1. Open a terminal in the project root directory.
|
|
2. Start Julia with the project environment activated:
|
|
```bash
|
|
julia --project=.
|
|
```
|
|
3. Enter the package manager mode by pressing `]`.
|
|
4. Run the `instantiate` command:
|
|
```julia
|
|
(DVR-jl) pkg> instantiate
|
|
```
|
|
|
|
Alternatively, you can run this single command from your terminal:
|
|
```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.
|
