Time-evolving block decimation
The time-evolving block decimation (TEBD) algorithm is a numerical scheme used to simulate one-dimensional quantum many-body systems, characterized by at most nearest-neighbour interactions. It is dubbed "time-evolving block decimation" because it dynamically identifies the relevant low-dimensional Hilbert subspaces of an exponentially larger original Hilbert space.
