School NANO SCIENCES Autonomous Quantum Clocks: Does Thermodynamics Limit Our Ability to Measure Time? Time remains one of the least well-understood concepts in physics, most notably in quantum mechanics. A central goal is to find the fundamental limits of measuring time. One of the main obstacles is the fact that time is not an observable and thus has to be measured indirectly. Here, we explore these questions by introducing a model of time measurements that is complete and autonomous. Specifically, our autonomous quantum clock consists of a system out of thermal equilibrium-a prerequisite for any system to function as a clock-powered by minima ... 14:00 - 15:30 Weekly Seminar Circular polarization: a window to new physics School ASTRONOMY In this seminar, I will talk about new interactions of CMB photons. Then, using quantum Boltzmann equation I calculate the effects of new interactions on a system of CMB photons. I will show that those new interactions that violate parity, can produce circular polarization. Measurement of CMB circular polarization will be signatures of new physics in the early universe ... 14:00 - 15:00 Seminar on Combinatorics and Computing Cryptocurrencies School MATHEMATICS . ... 14:00 - 17:00 Seminar on Operator Algebra and its Applications AF-embeddability (I). School MATHEMATICS . ... 14:00 - 15:00 Weekly Seminar Understanding Metal Cluster with Theoretical Spectroscopy School NANO SCIENCES Understanding Metal Cluster with Theoretical Spectroscopy Atomic and molecular clusters exhibit unique chemical and physical properties that are markedly different from the bulk phase. For small metal clusters, chemical reactivity as well as optical and magnetic properties are known to depend strongly on the cluster size, but it is still very difficult to predict structural and electronic properties from knowledge of cluster composition and size only. To improve our understanding of these important model systems, the experimental and theoretical techniques are combined. Therefore, the devel ... |
