| 12:30 - 13:30 Joint Astronomy and Particle Physics Colloquium – Hybrid Format On searching Black Holes School PARTICLES AND ACCELERATORS Abstract: In this lecture, I will discuss recent efforts on discovery of black holes. I will also explain and elaborate on cases in which I have contributed in these discoveries.

The goal is to identify quantum paramagnetic phases like spin liquids and valence bond solids, which, despite lacking magnetic order, hold significant potential for different applications. Using a graph-based projected entangled pair state (gPEPS) method in the thermodynamic limit, the study mapped the model's phase diagram, revealing various phases including a valence bond solid (VBS) with zero magnetization, ferromagnetic and Neel ordered phases, and a ... 14:00 - 15:00 Weekly Seminar Revolutionizing Ophthalmology Leveraging Computational Power and Experimental Precision for Data-Driven Eye Health Innovations School BIOLOGICAL SCIENCES Retinal neovascularization is a major cause of irreversible vision impairment in the elderly. The current first-line treatment involves the intravitreal administration of anti-vascular endothelial growth factor (anti-VEGF) agents to inhibit abnormal blood vessel growth in the retina. While initially effective, some patients experience a progressive decline in response to anti-VEGF therapy after repeated administrations. This diminishing efficacy is often attributed to the development of resistance through overlapping and compensatory pathways. Future therapeutic strategies may focus on identifying novel targets, rewiring pathological signalin ... 16:00 - 17:00 Mathematics Colloquium Algebraic Coding in the Era of AI School MATHEMATICS The emergence of AI, particularly large language models (LLMs), has dramatically reshaped the requirements for error-correcting codes, particularly in the realm of memory I/O during training. Massive data transfers involved in training LLMs necessitate extremely robust error correction to prevent costly retraining scenarios triggered by undetected errors (Silent Data Corruption). Traditional iterative decoding techniques are inadequate due to their latency constraints, pushing the field towards combinational logic implementations capable of achieving multiple-error correction under extremely tight latency budgets. Algebraic codes, which once ... 18:00 - 19:30 Physics Colloquium Do we understand early Universe cosmology? School PHYSICS Date and time, 6-7:30pm, Wednesday 21 May 2025 (31 Ordibehesht 1404) Venue: Online Link https://www.skyroom.online/ch/schoolofphysics/colloquium Abstract I will argue that the usual effective field theory techniques break down in the rapdily expanding background of the early universe. The TCC ("Trans-Planckian Censorship Criterion") plays a key role in the argument. I will then discuss an attempt to obtain an emerging metric space-time and early universe cosmology starting from a quantum mechani ... |
