Condensed-Matter Seminar: "The Ramp Reversal Memory – A perspective after nearly a decade"
- Start time: 12:00pm
- End date: Thursday, May 8th
- End time: 01:30pm
- Lecturer: Amos Sharoni, Department of Physics, Bar Ilan University
  
  Abstract:
  The ramp reversal memory (RRM) is a non-volatile memory effect we discovered
  originally in correlated oxides with temperature-driven insulator-metal transitions (IMT), such as VO 2 , V 2 O 3 and NdNiO 3 . The memory appears as a resistance increase at predefined temperatures that are set or erased by simple heating-cooling (i.e., ramp-reversal) protocols. The characteristics of this memory effect do not coincide with any previously reported history or memory effects.
  In this talk we will review our current understanding of the RRM. We will overview
  the main properties of the memory effect, show how the memory appears in different systems, discuss what features are system dependent, and review the ingredients required for the effect to arise. We will conclude that the RRM is indeed an emergent phenomenon, where the underlying physical mechanism can change from system to system. Thus, it is expected to appear in additional materials with relevant ingredients.

Nonlinear Physics seminar: "Run and tumble dynamics in 1D"
- Start time: 12:00pm
- End date: Wednesday, May 14th
- End time: 01:30pm
- Lecturer: Prof. Oded Farago, Ben-Gurion University in the Negev, Israel
  Abstract:
  Run and tumble dynamics is a model that typically describes the motion of self-propelled particles, especially in the context of bacterial motility. It’s most famously used to model the behavior of E. coli and similar microorganisms. In the simplest setting, a run-and-tumble particle (RTP) moves with a fixed speed, undergoing random tumbling events at a constant rate. In one-dimension (1D), the overdamped dynamics of an RTP is described by a set of two Fokker-Planck equations, and the steady-state distribution is known for any arbitrary confining potential. In the talk, I will present three recent works presenting different extensions of the RTP model that consider: (i) inertial effects [1], (ii) tumbling at a non-constant rate (non-Markovian dynamics) [2], and (iii) run-and-tumble dynamics at a finite temperature (in contact with a heat bath) [3].

Condensed-Matter Seminar: "Time-resolved attosecond interferometry"
- Start time: 12:00pm
- End date: Thursday, May 15th
- End time: 01:30pm
- Lecturer: Omer Kneller, Department of Complex Systems, Faculty of Physics, Weizmann Institute of ScienceAbstract:Attosecond science has revolutionized the ability to capture extremely fast phenomena in nature, opening a window into a new temporal regime, in which electron dynamics are observed on their natural time scale. Attosecond metrology relies on the ability to produce optical pulses, having attosecond duration, where the electronic dynamics are imprinted in the spectral intensity, phase and polarization state of such attosecond pulses. However, the optical measurement resolves only the spectral intensity while the phase and polarization information are lost, preventing a direct access to the full information encoded in the attosecond signal.In my talk, I will describe how we extend one of the most fundamental optical schemes, interferometry, to the attosecond timescale. Our state-of-the-art all-optical attosecond interferometry scheme reveals some of the fastest phenomena in nature, such as the moment at which an electron is photoionized or the evolution of an electronic wavefunction under the tunneling barrier, as it propagates in a classically forbidden region. Our recent development of attosecond transient interferometry enables us to decouple and directly follow the temporal evolution of individual quantum paths induced in a light-driven system.Bio: After completing his BSc in physics at the Hebrew University of Jerusalem, Dr. Kneller joined Prof. Nirit Dudovich’s lab at the Weizmann Institute, where he performed his MSc and PhD research in attosecond science. Dr. Kneller recently joined the group of Prof. Rupert Huber at the University of Regensburg, Germany, as a postdoctoral fellow, studying lightwave electronics. References:1. D. Azoury, O.
