12:00 - 13:15 Analysis Seminar Amenable Actions of Discrete Quantum Groups on von Neumann Algebras School MATHEMATICS We introduce the notion of Zimmer amenability for actions of discrete quantum groups on von Neumann algebras. We prove generalizations of several fundamental results of the theory in the noncommutative case. In particular, we give a characterization of Zimmer amenability of an action $\alpha:{\Bbb G}\curvearrowright N$ in terms of $\hat{\Bbb{G}}$-injectivity of the von Neumann algebra crossed product $N\ltimes_\alpha\Bbb G$. As an application we show that the actions of any discrete quantum group on its Poisson boundaries are always amenable. ... 14:00 - 16:00 Theoretical Neuroscience Journal Club Functional connectivity dynamically evolves on multiple time-scales over a static structural connectome: Models and mechanisms School COGNITIVE SCIENCES Venue: School of Cognitive Sciences, Institute for Research in Fundamental Sciences (IPM), Opposite the ARAJ, Artesh Highway, Tehran, Iran ... 14:00 - 15:00 Weekly Seminar Quantum-classical equivalence and ground-state factorization School NANO SCIENCES Quantum-classical equivalence and ground-state factorization We have performed an analytical study of quantum-classical equivalence for quantum XY-spin chains with arbitrary interactions to explore the classical counterpart of the factorizing magnetic fields that drive the system into a separable ground state. We demonstrate that the factorizing line in parameter space of a quantum model is equivalent to the so-called natural boundary that emerges in mapping the quantum XY-model onto the two dimensional classical Ising model. As a result, we show that the quantum systems with the non-factorizable ground state could not be ma ... 14:00 - 15:00 Weekly Seminar Condensed Matter and Statistical Physics Group Quantum-classical equivalence and ground-state factorization School PHYSICS Seminar Room (classroom A), Farmanieh Building, IPM ... 15:00 - 16:00 Weekly Seminar Calorimetric Dark Matter Detection With Galactic Center Gas Clouds School PARTICLES AND ACCELERATORS Dark matter heating of gas clouds hundreds of parsecs from the Milky Way Galactic center provides us a powerful new test of dark matter interactions. To illustrate, the leading bound on nucleon scattering for 10-100 MeV mass dark matter can be derived using this method. Furthermore, millicharged dark matter models, including those proposed to match the recent EDGES 21 cm absorption anomaly can be constrained from gas cloud's cooling rate. For Galactic center gas clouds, galactic fields magnetic deflection of electromagnetically charged dark matter is mitigated, because the magnetic fields around the Galactic center are poloidal, as opposed to ... 16:00 - 17:00 Monthly Colloquium Precision medicine in oncology: still not ready for prime time? School NANO SCIENCES Precision medicine in oncology: still not ready for prime time? Although many advances have been made in detecting, diagnosis and treating cancer, chemotherapy (the primary means of treatment) is only effective in 25% of those treated. This failure in oncology somewhat relies on trial-and-error or one-size-fits-all approach in which everyone gets the same therapeutic regimen, regardless of genotype. Therefore, treatment strategy in oncology is shifting to precision medicine. Precision medicine is described as the tailoring of medical treatment to the individual characteristics of each patient. In this regard, physici ... |
