Lindbladian
In quantum mechanics, the Franke–Gorini–Kossakowski–Sudarshan–Lindblad (FGKSL) master equation (named after Valentin Franke, Vittorio Gorini, Andrzej Kossakowski, George Sudarshan and Göran Lindblad), Gorini–Kossakowski–Sudarshan–Lindblad (GKSL) master equation, master equation in Lindblad form, quantum Liouvillian, or Lindbladian is one of the general forms of Markovian master equations describing open quantum systems. It generalizes the Schrödinger equation to open quantum systems; that is, systems in contact with their surroundings.
