+Summer Projects by 4th and 5th years
+
+<!--more-->
+
+We are excited to announce Ensemble Summer Project Expo 2025, an event where our senior undergraduates will share the projects and academic explorations they undertook over the summer. This is a great chance for all of us to hear directly from them about their research experiences, problem-solving approaches, and the diverse directions they explored. 
+ 
+Date: **Wednesday, 10th September**
+Venue: **F08A, OPB**
+
+At the end of Jay's talk, he will describe the application and selection procedure of ANU-FRT scholarship programme by the UG Office. This might be of interest to all majors, specially from the Batch of 2023.

+title: Phase behavior of Cacio e Pepe sauce

+Pasta alla Cacio e Pepe is a beloved Italian classic, known for its simple yet iconic combination of pasta, pecorino cheese, and pepper. However, despite its minimal ingredient list, achieving the perfect creamy sauce remains a culinary challenge. In this talk, we delve into the science of Cacio e Pepe, exploring the phase behavior of the sauce with varying proportions of cheese, water, and starch. Our findings highlight starch concentration as a critical factor for sauce stability. Specifically, we identify a threshold below which starch concentrations (less than 1% relative to cheese mass) result in system-wide clumping, a condition we term the "Mozzarella Phase", characterized by an undesirable, separated texture. Additionally, we explore how cheese-to-water ratios at a fixed starch level affect stability, revealing a lower critical solution temperature that we rationalize using a simplified free-energy model. To make these insights actionable, we'll share some practical tips drawn from our study to help consistently achieve a perfectly creamy and stable sauce.
+ 
+In short: it is funny, but the science is serious. We believe this will be an engaging session for anyone interested in physics, modelling or simply craving the joy of discovering, and would certainly be more amusing than our formal lectures.

+Talk
+
+<!--more-->
+
+We are delighted to invite you to a talk by Nandagopal Manoj (PhD, Caltech) on an exciting topic at the interface of quantum information and many-body physics.
+The talk is about entanglement transitions in random unitary circuits with mid-circuit measurements, mostly as an excuse to introduce you to thinking about quantum dynamics using tensor networks. It will be based on Brian Skinner’s 2023 lecture notes (arXiv:2307.02986)
+ 
+Event Details
+Speaker : **Nandogopal Manoj (PhD student at Caltech)**
+Date: **17th September (Wednesday)**
+Time: **6:30 PM**
+Venue: **F-08A, OPB**
+ 
+##About the Speaker 
+Nandagopal Manoj is currently pursuing his PhD in Physics at Caltech, working broadly in the areas of quantum many-body physics and quantum information. He completed his undergraduate studies at IISc, and it is a pleasure to have him return to share his work with the IISc community.
+ 
+##Prerequisites 
+Necessary: Elementary Quantum mechanics: bra–ket notation, unitary operators, Born rule for quantum measurement, and how to write Hilbert spaces and operators for two (or more) spin-1/2 degrees of freedom using individual Hilbert spaces and Pauli operators.
+Helpful if familiar with: Surface-level knowledge of Von Neumann entanglement entropy, Singular Value Decomposition (SVD), Schmidt decomposition, scale invariance in (classical) phase transitions, and percolation transitions.
+We hope to see you all there! After the talk, the speaker will also be glad to chat informally about research directions, project ideas, and graduate school applications.
