Nonequilibrium Green's functions (NEGF) have emerged as a pivotal theoretical framework for investigating the time-dependent behaviour of quantum many-body systems. By tracking the evolution of ...

ITHACA, N.Y. -- Math is the language of the physical world, and Alex Townsend sees mathematical patterns everywhere: in weather, in the way soundwaves move, and even in the spots or stripes zebra fish ...

The change in electric potential as a result of lightning in a one-dimensional domain is evaluated. Green’s function is used to evaluate the new potential. The change in the electric potential is a ...
