  • Imaging with scattered light
    Seminar:  Colloquium QUEST Center event:  Speaker:  Ori Katz, Hebrew University Date :  08/04/2019 – 10:30 Place:  Physics 301 Abstract:  Random scattering of light in complex samples such as biological tissue renders most objects opaque to optical imaging techniques, diffusing every focused beam into a complicated speckle pattern. However, although random, scattering is a deterministic process, and it can be undone and also exploited by controlling the incident opt …
  • Future of Analog Quantum Computing: Hopes and Hinderances
    Seminar:  Optics Seminar QUEST Center event:  Speaker:  Itay Hen (University of Southern California) Date :  01/05/2019 – 12:00 – 13:00 Place:  Nano (206), 9th floor Abstract:  It is yet unclear whether even ideal analog quantum machines can perform computational tasks faster than their classical counterparts. I will discuss the results of several recent studies that suggest the existence of several fundamental limiting factors to, as well as a couple of promising d …
  • Spin Ensembles in Diamond for Sensing and Many-Body Physics
    Seminar:  Optics Seminar QUEST Center event:  Speaker:  Dr. Dima Farfurnik, Hebrew University (Nir Bargil's group) Date :  13/03/2019 – 12:00 – 13:00 Place:  Nano Center, 9th floor seminar room Abstract:  The study of quantum many-body spin physics in realistic solid-state platforms has been a long-standing goal in quantum and condensed-matter physics. We demonstrate separate steps required to reach this goal using NV centers in diamond. First, standard (TEM) e …
  • Nonlinear light-matter interaction: from superconducting qubits to spins in diamond
    Seminar:  Condensed Matter Resnick seminar QUEST Center event:  Speaker:  Eyal Buks Date :  28/02/2019 – 12:15 – 13:30 Place:  Nano Building 9th floor Abstract:  Cavity quantum electrodynamics (CQED) is the study of the interaction between matter and photons confined in a cavity. In the Jaynes-Cummings model the matter is described using the two-level approximation, and only a single cavity mode is taken into account. The interaction has a relatively large effect wh …
  • Strong repulsive and attractive interactions in correlated dipolar quantum fluids
    Seminar:  Condensed Matter Resnick seminar QUEST Center event:  Speaker:  Ronen Rapaport (Weizmann) Date :  10/01/2019 – 12:30 – 13:30 Place:  Nano (206), 9th floor Abstract:  Quantum fluids of matter with long range, anisotropic interactions display rich emergent collective phenomena. A prominent example is the dipole-dipole interaction, which has recently been addressed by a growing community, both from atomic physics as well as from condensed matter physics, with …
  • Imaging Topological Materials
    Seminar:  Colloquium QUEST Center event:  Speaker:  Jenny Hoffman, Harvard Universtiy, USA Date :  14/01/2019 – 10:30 Place:  Physics 301 Abstract:      Today’s electronic technology – the pixels on the screen and the process to print the words on the page – are all made possible by the controlled motion of an electron’s charge. In the last decade, the discovery of topological band insulators with robust spin-polarized surface state …
  • Observation of stimulated Hawking radiation in an optical analogue
    Seminar:  Optics Seminar QUEST Center event:  Speaker:  Yehonathan Drori, Weizmann Institute of Science Date :  02/01/2019 – 14:00 – 15:00 Place:  Nano Center, 9th floor seminar room Abstract:  Hawking radiation, the quantum emission of light from black holes, is too weak to be measured from known astrophysical sources. However, experimental observations can be made in laboratory settings using analogue systems. In such systems, the space-time geometry of the event …
