36218923 | cond-mat/0406426 | 2004-06-18 | Matrix Product Density Operators: Simulation of finite-T and dissipative systems | We show how to simulate numerically both the evolution of 1D quantum systems under dissipation as well as in thermal equilibrium. The method applies to both finite and inhomogeneous systems and it is based on two ideas: (a) a representation for density operators which extends that of matrix product states to mixed stat... | [

This allows us to specify in a general setting bipartite state properties sufficient for the validity of a cl... | [

The algorithm can be used, e.g., to construct thermal states or to simulate real time evolutions given by a generic master equation. Its two main ingredients are (i) a superoperator renormalization scheme to efficiently de... | [

Of fundamental importance is the photon yield due to excitation by electrons, in air of various densities and temperatures.

Here we critically revise its viability by noting that for the direct production of giant planets it is not enough for protoplanetary disks to be gravitationally unstable. They must also be able to cool... | [
