Entropy injection from an environment enlarges the effective Hilbert space and enhances many-body chaos, demonstrated via analytical computation of relaxation and Lyapunov exponent in a solvable complex Brownian SYK model.
Derives explicit expressions for the energy transfer rate and heat conductance up to second order in coupling strength for randomly coupled quantum systems using Gaussian random matrix modeling in the large-N limit.
