Tomorrow

Physics Colloquium : "Beyond the Higgs with Amplitude Methods"
- Start time: 12:00pm
- End date: Monday, January 6th
- End time: 01:30pm
- Lecturer: Prof. Yael Shadmi, TechnionAbstract:The LHC experiments are now probing the Higgs interaction for the first time. Over the next two decades, they will supply a wealth of precise measurements of processes involving the Higgs and electroweak gauge bosons, which may provide clues to the origin of the Higgs potential and in particular, to the origin of the weak scale. How do we interpret these measurements? We will describe a model-independent approach, based on just the physical degrees of freedom, namely, the known particles, in terms of amplitudes.

Weekly Seminar Quantum Center:"New Avenues for Quantum Information Processing with Light-Matter Interactions"
- Start time: 11:45am
- End date: Tuesday, January 7th
- End time: 01:15pm
- Lecturer: Aviv Karnieli, Stanford UniversityAbstract:Light-matter interaction (LMI) underpins numerous quantum technologies, yet persistentchallenges—such as decoherence, scalability, and speed—limit the advancement ofquantum information processing (QIP) in this promising platform. These limitationsmotivate the search for alternative quantum hardware leveraging LMI to overcomethese barriers and unveil new opportunities for QIP.In this seminar, I will demonstrate how combining diverse concepts, components, andbuilding blocks in quantum optics leads to such novel approaches for QIP. First, I willintroduce free electrons as a new and promising resource in quantum optics, enablingultrafast operation, strong coupling, and single-photon nonlinearities in cavity quantumelectrodynamics (QED). Next, I will show how the integration of concepts from nonlinearoptics into waveguide QED unlocks novel schemes for many-body entanglementgeneration and enables access to exotic physics in atomic arrays. Finally, I will presenta scalable architecture for processing high-dimensional photonic entanglement, inspiredby the variational principle in physics and realized through self-configuring photonicnetworks.Karnieli*, Tsesses*, et al PRX Quantum 5, 010339 (2024)Karnieli and Fan, Science Advances 9, eadh2425 (2023)Karnieli*, Roques-Carmes*, et al, ACS Photonics 11, 3401 (2024)Karnieli et al, accepted to Physical Review Research (2024)Roques-Carmes*, Karnieli* et al, arXiv:2407.16849 (2024)Karnieli*, Roques-Carmes*, et al (submitted to CLE0 2025)

Astrolunch: Shmuel Balberg

- Title: Destructive stellar collisions in galactic nucleiSpeaker: Shmuel Balberg (The Hebrew University of Jerusalem)Abstract: The centers of galaxies host both a supermassive black hole (SMBH) and a dense stellar cluster. Physical collisions between stars in such an environment can involve sufficiently high velocities so that the colliding stars are completely destroyed. Destructive collisions (DCs) are therefore inevitable, but at what rate? How do they compare, and possibly compete, with other stellar destruction mechanisms that are unique to galactic nuclei? It appears that stars captured through tidal disruption of binaries by the SMBH hold the key to the DC rate, which should be astrophysically significant, and may even be comparable to that of tidal disruption events (TDEs). Given the total energy, mass and location of DCs, the primary flare that follows them should also be similar to that of TDEs, as streams of the disrupted gas shock each other while flowing toward the central black hole. Some potential differences from TDEs may, however, allow to observationally identify DCs as a separate subclass of bright nuclear transients.
