Upper bound about cross-sections inside black holes and complexity growth rate
Run-Qiu Yang
This paper studies cross-sections inside black holes and conjectures a universal inequality: in a static -dimensional asymptotically planar/spherical Schwarzschild-AdS space…
To be unitary-invariant or not?: a simple but non-trivial proposal for the complexity between states in quantum mechanics/field theory
Run-Qiu Yang, Yu-Sen An, Chao Niu +2
We make comments on some shortcomings of the non-unitary-invariant and non-bi-invariant complexity in quantum mechanics/field theory and argue that the unitary-invariant and bi-inv…
Time evolution of the complexity in chaotic systems: concrete examples
Run-Qiu Yang, Keun-Young Kim
We investigate the time evolution of the complexity of the operator by the Sachdev-Ye-Kitaev (SYK) model with Majorana fermions. We follow Nielsen's idea of complexity geometry…
Simulating quantum field theory in curved spacetime with quantum many-body systems
Run-Qiu Yang, Hui Liu, Shining Zhu +2
This paper proposes a new general framework to build a one-to-one correspondence between quantum field theories in static 1+1 dimensional curved spacetime and quantum many-body sys…
Complexity of Holographic Superconductors
Run-Qiu Yang, Hyun-Sik Jeong, Chao Niu +1
We study the complexity of holographic superconductors (Einstein-Maxwell-complex scalar actions in dimension) by the `complexity = volume' (CV) conjecture. First, it seems th…
