Finite-size effects on current correlation functions
Shunda Chen, Yong Zhang, Jiao Wang +1
We study why the calculation of current correlation functions (CCFs) still suffers from finite size effects even when the periodic boundary condition is taken. Two important one di…
Thermal Rectification in Graded Materials
Jiao Wang, Emmanuel Pereira, Giulio Casati
In order to identify the basic conditions for thermal rectification we investigate a simple model with non-uniform, graded mass distribution. The existence of thermal rectification…
Breakdown of the power-law decay prediction of the heat current correlation in one-dimensional momentum conserving lattices
Shunda Chen, Yong Zhang, Jiao Wang +1
We show that the asymmetric inter-particle interactions can induce rapid decay of the heat current correlation in one-dimensional momentum conserving lattices. When the asymmetry d…
Long-lasting Exponential Spreading in Periodically Driven Quantum Systems
Jiao Wang, Italo Guarneri, Giulio Casati +1
Using a dynamical model relevant to cold-atom experiments, we show that long-lasting exponential spreading of wave packets in momentum space is possible. Numerical results are expl…
