Quantum open system theory: bipartite aspects.
We demonstrate in straightforward calculations that even under ideally weak noise the relaxation of bipartite open quantum systems contains elements not previously encountered in quantum noise physics. While additivity of decay rates is known to be generic for decoherence of a single system, we demonstrate that it breaks down for bipartite coherence of even the simplest composite systems.
متن کاملTheory of open quantum systems
A quantum dissipation theory is constructed with the system–bath interaction being treated rigorously at the second-order cumulant level for both reduced dynamics and initial canonical boundary condition. The theory is valid for arbitrary bath correlation functions and time-dependent external driving fields, and satisfies correlated detailed-balance relation at any temperatures. The general for...
متن کاملMathematical Aspects of Quantum Theory and Quantization
Acknowledgements : In preparing these notes the mathematical erudition of my friend Henk Pijls has been indispensable. My wife Adrienne gave essential support during the school and was also very helpful in practical matters. Amine Bahayou, the main organizer of the school, deserves much praise for his tireless efforts. The interest shown by the students was a great stimulus.
متن کاملNonequilibrium Aspects of Quantum Field Theory
We have developed a method for extracting equilibrium observables from non-equilibrium simulations by rapidly changing the temperature and recording the subsequent evolution of the Polyakov loop. Both nucleation and spinodal decomposition are observed to occur. In the latter case the Polyakov loop correlation function shows exponential growth for wavenumbers less than or equal to the critical w...
متن کاملPhilosophical Aspects of Quantum Field Theory: II
According to a regnant criterion of physical equivalence for quantum theories, a quantum field theory (QFT) typically admits continuously many physically inequivalent realizations. This, the second of a two-part introduction to topics in the philosophy of QFT, continues the investigation of this alarming circumstance. It begins with a brief catalog of quantum field theoretic examples of this no...
