    Large-scale simulations demonstrate that chaos is responsible for stochastic heating of dense plasma by intense laser energy. This image shows a snapshot of electron distribution phase space (position/momentum) from the dense plasma taken from PIC simulations, illustrating the so-called 'stretching and folding' mechanism responsible for the emergence of chaos in physical systems.
