TL;DR: This work investigates notions of complexity of states in continuous many-body quantum systems by focusing on Gaussian states which include ground states of free quantum field theories and their approximations encountered in the context of the continuous version of the multiscale entanglement renormalization ansatz.

TL;DR: In this paper, the complexity of a holographic boundary state can be computed by evaluating the gravitational action on a bulk region known as the Wheeler-DeWitt patch, and it was shown that for boundary dimensions d > 2, the difference in the complexities grows linearly with the thermal entropy at high temperatures.

TL;DR: In this paper, the authors evaluate the full time dependence of holographic complexity in various eternal black hole backgrounds using both the complexity=action (CA) and the complexity-volume (CV) conjectures and conclude that the rate of change of complexity is a monotonically increasing function of time, which saturates from below to a positive constant in the late time limit.

TL;DR: In this article, the authors examined holographic complexity in time-dependent Vaidya spacetimes with both the complexity$$volume (CV) and complexity$=$action (CA) proposals.

TL;DR: In this article, the complexity of circuit complexity for thermofield double (TFD) states in free scalar quantum field theories using the Nielsen approach has been investigated and it has been shown that the complexity evolves in time and saturates after a time of the order of the inverse temperature.
