We study the density matrix for systems with an arbitrary linear dissipative mechanism at finite temperature. We show how one may derive the tunneling Lagrangians using general methods in statistical mechanics. The derivation is phenomenological in nature and as such does not proceed from any partic
Dissipation and decoherence are reviewed for quantum magnets, in which quantum fluctuations render a semi-classical picture incorrect. This is done for 3 examples in detail. First, the tunneling of magnetic domain walls is considered-this is a typical quantum soliton problem, with dissipation being
