报告摘要：In this work we report a classical simulation strategy that we have proposed recently used to simulate quantum dynamics, in particular quantum walks. This strategy is based on a classical device of linearly coupled chain of springs together with the technique of Hilbert transform. Through this strategy, we obtain the quantum wave function from the classical evolution. Specially, this goal is achieved with the classical momenta of the particles on the chain and their Hilbert transform, from which we construct the many-body momentum and Hilbert transformed momentum pair correlation functions yielding the real and imaginary parts of the wave function, respectively. With such a wave function, we show that the classical chain’s energy and heat spreading densities can be related to the wave function’s modulus square. This relation provides a particular perspective from quantum aspects to understand ballistic energy and heat transport.
