Dynamical Objectivity in Quantum Brownian Motion
Classical objectivity as a property of quantum states---a view proposed to
explain the observer-independent character of our world from quantum theory, is
an important step in bridging the quantum-classical gap. It was recently
derived in terms of spectrum broadcast structures for small objects embedded in
noisy photon-like environments. However, two fundamental problems have arisen:
a description of objective motion and applicability to other types of
environments. Here we derive an example of objective states of motion in
quantum mechanics by showing a formation of dynamical spectrum broadcast
structures in the celebrated, realistic model of decoherence---Quantum Brownian
Motion. We do it for realistic, thermal environments and show their
noise-robustness. This opens a potentially new method of studying
quantum-to-classical transition.Comment: 6 pages, 3 figures, accepted for publication in EP
A view from outside: Russian literature in the works of the Ukrainian critic Mykola Yevshan
In the works of Mykola Yevshan (1890–1919), the leading critic of early Ukrainianmodernism, the issue of Russian literature is of particular significance. An analysis of Yevshan’s papers shows that he referred both to the literature and philosophical thought of Western Europe as well as to Russian literary tradition. He particularly esteemed the achievements of Russian realism, considering them as having universal and ageless values. He hoped to find the answers to questions of an existential and social nature which troubled modernists in the works of the greatest Russian writers, Fyodor Dostoyevsky and Leo Tolstoy.In the works of Mykola Yevshan (1890–1919), the leading critic of early Ukrainianmodernism, the issue of Russian literature is of particular significance.
