Real Time Quantum Gravity Dynamics from Classical Statistical Yang-Mills Simulations

Understand

We perform microcanonical classical statistical lattice simulations of SU(N) Yang-Mills theory with eight scalars on a circle.

• Measuring the eigenvalue distribution of the spatial Wilson loop we find two distinct phases depending on the total energy and circle radius, which we tentatively interpret as corresponding to black hole and black string phases in a dual gravity picture.
• We proceed to study quenches by first preparing the system in one phase, rapidly changing the total energy, and monitoring the real-time system response.
• We observe that the system relaxes to the equilibrium phase corresponding to the new energy, in the process exhibiting characteristic damped oscillations.
