name: mxl-driver-tls description: This skill should be used when users want to run the built-in TLS (two-level system) driver in socket or embedded mode and need parameter conventions and example commands.

TLS driver (two-level system)

Use for lightweight benchmarks

• Use the built-in TLS driver (tls) for fast regression and simple light–matter prototyping.

Configure embedded mode

• Instantiate:
  • Molecule(driver="tls", driver_kwargs=dict(omega=..., mu12=..., orientation=..., pe_initial=..., checkpoint=..., restart=...))

Configure socket mode

• Launch one process per molecule:
  • mxl_driver --model tls [--unix --address <name> | --address <host> --port <port>] --param "omega=..., mu12=..., orientation=..., pe_initial=..."
• Keep the hub address/port/unixsocket consistent with the EM script.

Key parameters

• omega (a.u.), mu12 (a.u.), orientation (0|1|2 for x/y/z), pe_initial (0–1), checkpoint, restart.

Notes

• Prepare a coherent (superposition) initial TLS state by setting 0 < pe_initial < 1; this seeds emission into vacuum-like classical fields.
• Read outputs from molecule.additional_data_history (keys include time_au, Pe, Pg, dipoles, energies).
• Use post-processing guidance in skills/mxl-postprocess/SKILL.md.
