Circuit Complexity of Scalar and Tensor Perturbations in Luminal Einstein--Gauss--Bonnet Inflation
Tao Li, Hai-Bing Fu, Lei-Hua Liu
We investigate the circuit complexity of primordial scalar and tensor perturbations in the luminal branch of Einstein-Gauss-Bonnet (EGB) inflation. We construct the Hamiltonians fr…

Circuit complexity of coupled four-mode squeezed states in two-field inflation
Tao Li, Hai-Bing Fu, Lei-Hua Liu
We study the circuit complexity of coupled curvature and entropy perturbations in two-field inflation. We start from the quadratic action and derive the full Hamiltonian. The Hamil…
