With the rapid development of urban traffic, a large number vehicles in cities not only bring convenience to people, but also series traffic problems, including congestion and high accident rates. Driving speed waiting time are two important factors problems. To simulate real road flow, one-dimensional flow grid model was proposed, which considered nearest next neighbour car at same time, conne...

TBPLaS is an open-source software package for the accurate simulation of physical systems with arbitrary geometry and dimensionality utilizing tight-binding (TB) theory. It has intuitive object-oriented Python application interface (API) Cython/Fortran extensions performance-critical parts, ensuring both flexibility efficiency. Under hood, numerical calculations are mainly performed by exact di...

Non-Hermitian quantum systems have recently attracted considerable attention due to their exotic properties. Though many experimental realizations of non-Hermitian been reported, the non-Hermiticity usually resorts hard-to-control environments and cannot last for too long times. An alternative approach is use simulation with closed system, whereas how simulate Hamiltonian dynamics remains a gre...
