Tomorrow

Physics Colloquium : "Are `analog computers' back in fashion?"
- Start time: 12:00pm
- End date: Monday, December 2nd
- End time: 01:30pm
- Lecturer: Prof. Oren Raz, Weizmann InstituteAbstract:In the last decade there have been several efforts to use physical systems as 'physical computers': D-Wave is using super-conducting qubits as an adiabatic computer, the Israeli company Light-Solver uses lasers to find optimal solutions to optimization algorithm, HP is developing `memristor computation', and companies like Toshiba and Fujitsu are commercializing products like `Bifurcation machines' and `Digital annealers'... In the talk I will review this topic, show some results, what we do and don't understand, and try to provide some intuition on what physical mechanisms are expected to give real benefits.

Astrolunch: Cecilia Chirenti
- Start time: 04:00pm
- End date: Tuesday, December 3rd
- End time: 05:00pm
- Speaker: Prof. Cecilia Chirenti (Federal University of ABC, Santo Andre, Brazil; Department of Astronomy, University of Maryland, USA)Title: Quasi-periodic oscillations in short gamma-ray bursts and implications for neutron starsAbstract:Short gamma ray bursts (GRBs) have already been associated with binary neutron star mergers, which are also sources of gravitational waves. Numerical relativity simulations indicate that the merger can form a short-lived hypermassive neutron star (which could produce a millisecond magnetar), lasting for tens to hundreds of milliseconds before gravitational collapse forms a black hole. This neutron star remnant is expected to emit gravitational waves (GWs) with kHz frequencies that will be detectable by third generation ground-based GW detectors in the 2030s. Recently, kHz quasiperiodic oscillations were discovered in GRBs 910711 and 931101B, providing evidence for a hypermassive neutron star stage in these events. When analyzed together with new quasi-universal relations obtained from numerical relativity simulations, these detections provide a novel method to constrain the equation of state of the dense matter in neutron star cores.Zoom link:https://huji.zoom.us/j/83438422733?pwd=bO4fe7y4WgZ5OWdFjaUxulnbjurow1.1Meeting ID: 834 3842 2733Passcode: 294941 Contact: Dima Ofengeim
