Complete positivity on the subsystems level
M. Arsenijevic, J. Jeknic-Dugic, M. Dugic
We consider complete positivity of dynamics regarding subsystems of an open composite quantum system, which is subject of a completely positive dynamics. By "completely positive dy…
A minimalist approach to conceptualization of time in quantum theory
H. Kitada, J. Jeknic-Dugic, M. Arsenijevic +1
Ever since Schrodinger, Time in quantum theory is postulated Newtonian for every reference frame. With the help of certain known mathematical results, we show that the concept of t…
Generalized Kraus operators for the one-qubit depolarizing quantum channel
Momir Arsenijevic, Jasmina Jeknic-Dugic, Miroljub Dugic
Microscopic Hamiltonian models of the composite system "open system + environment" typically do not provide the operator-sum Kraus form of the open system's dynamical map. With the…
Entanglement Relativity in the Foundations of The Open Quantum Systems Theory
M. Arsenijevic, J. Jeknic-Dugic, D. Todorovic +1
Realistic many-particle systems dynamically exchange particles with their environments. In classical physics, small variations in the number of constituent particles are commonly c…
A Limitation of the Nakajima-Zwanzig projection method
M. Arsenijevic, J. Jeknic-Dugic, M. Dugic
There is current interest in dynamical description of dif- ferent decompositions of a quantum system into subsystems. We investi- gate usefulness of the Nakajima-Zwanzig projection…
Asymptotic dynamics of the alternate degrees of freedom for a two-mode system: an analytically solvable model
M. Arsenijevic, J. Jeknic-Dugic, M. Dugic
The composite systems can be non-uniquely decomposed into parts (subsystems). Not all decompositions (structures) of a composite system are equally physically relevant. In this pap…
