Complexity of operators generated by quantum mechanical Hamiltonians
Run-Qiu Yang, Keun-Young Kim
We propose how to compute the complexity of operators generated by Hamiltonians in quantum field theory (QFT) and quantum mechanics (QM). The Hamiltonians in QFT/QM and quantum cir…
Holographic entanglement of purification for thermofield double states and thermal quench
Run-Qiu Yang, Cheng-Yong Zhang, Wen-Ming Li
We explore the properties of holographic entanglement of purification (EoP) for two disjoint strips in the Schwarzschild-AdS black brane and the Vaidya-AdS black brane spacetimes.…
More on complexity of operators in quantum field theory
Run-Qiu Yang, Yu-Sen An, Chao Niu +2
Recently it has been shown that the complexity of SU() operator is determined by the geodesic length in a bi-invariant Finsler geometry, which is constrained by some symmetries…
Holographic subregion complexity under a thermal quench
Bin Chen, Wen-Ming Li, Run-Qiu Yang +2
We study the evolution of holographic subregion complexity under a thermal quench in this paper. From the subregion CV proposal in the AdS/CFT correspondence, the subregion complex…
Principles and symmetries of complexity in quantum field theory
Run-Qiu Yang, Yu-Sen An, Chao Niu +2
Based on general and minimal properties of the {\it discrete} circuit complexity, we define the complexity in {\it continuous} systems in a geometrical way. We first show that the…
