WebbDissipative phase transitions (DPT) occur when a small quantum system interacts with a bath of harmonic oscillators. At equilibrium, DPTs are accompanied by an entropy change, signaling the loss of coherence. Despite extensive efforts, equilibrium DPTs have yet to be observed. Here, we demonstrate that ongoing experiments on double quantum dots that … WebbOrigin of quantum Zeno effect. The quantum Zeno effect was first presented in a 1977 paper called “The Zeno’s Paradox in Quantum Theory,” written by Baidyanaith Misra and …

WebbWe develop the idea by combining a mathematical theory of consciousness (integrated information theory) with an account of quantum collapse dynamics (continuous spontaneous localization). Simple versions of the theory are falsified by the quantum Zeno effect, but more complex versions remain compatible with empirical evidence. WebbIn this work a simple classical analog of the quantum Zeno effect will be suggested. Namely, as it is well known, in the quantum mechanics, in the limit of the infinite series of alternative short dynamical evolution and measurement, an unstable quantum system will never decay, that is called quantum Zeno effect.

It is well known that by repeatedly measuring a quantum system it is possible to completely freeze its dynamics into a well defined state, a signature of the … WebbIn 2010, the Veterans Administration (VA) implemented a medical home model termed the Patient Aligned Care Teams (PACT), with reorganization of staff into small teams (teamlets) as a core feature. OBJECTIVE: To examine the early experiences of primary care personnel as they assumed new roles through reorganization into teamlets.

WebbQuantum mechanics predicts that our physical reality is influenced by events that can potentially happen but factually do not occur. Interaction-free measurements (IFMs) exploit this counterintuitive influence to detect the presence of an object without requiring any interaction with it. Here we propose and realize an IFM concept based on an unstable … WebbKolkata, West Bengal, India. Worked on two research projects. 1.
