(Online) Seminar series on Indian scientists: Nov 21st: 3 - 5 PM@IITGN
Published on : 07-Nov-2020
We are glad to announce the second edition of the event: Seminar series on Indian scientists.
In the first half of the 20th century, there was a great renaissance of modern scientific thinking in India starting from the pioneering works by J. C Bose. The pioneers of modern Indian Science & Mathematics from this era contributed significantly to contemporary scientific understanding. At the same time, they motivated and led the national movement to create scientific institutions in India.
The “Seminar series on Indian scientists” aims to honour the contributions of these towering figures of Indian Science & Mathematics.
In this second edition, on Saturday 21st November 2020, there will be two ONLINE seminars on the life and works of Harish-Chandra and CV Raman. The speakers are
1. November 21st, 2020: 3:00 PM - 4:00 PM
Harish-Chandra - The Mathematician and the Artist
Prof. C S Aravinda
TIFR CAM, Bangalore
2. November 21st, 2020: 4:05 PM - 5:05 PM
The life, works and legacy of Prof. C V Raman
Prof. Rupak Banerjee
Both the talks may cover a few technical aspects, they will also deal with the historical and social contexts in which those pioneers worked. As such, they should appeal to faculty and students across a wide range of disciplines.

Online physics colloquium: Conservation of Quantum Information, 4:30 PM, 21st October
Published on : 14-Oct-2020
Prof. Arun K. Pati from HRI, Allahabad, will give a colloquium on 21st October (Wednesday). We will have the talk between 4:30 PM to 5:30 PM.
Title and abstract are given below.
Title: Conservation of Quantum Information
Abstract: The linearity and the unitarity are two fundamental tenets of quantum mechanics. Any consequence that follows from these two must be respected. We will discuss how the stronger no-cloning and the no-deleting theorems suggest that we cannot create quantum information nor can we destroy it. Further, we will discuss the implication of the no-hiding theorem which states that if the information is lost from one of the systems, it must move to some other part of the universe. Thus, the conservation of quantum information holds for all physical processes. Finally, we will discuss the no-masking theorem and its ramifications in quantum information.
Online physics colloquium: "Fire burn, and cauldron bubble: Probing the Milky Way star formation and the interstellar medium using radio observations", 4:30 PM, 14th October
Published on : 13-Oct-2020
We will have a colloquium (online via zoom) by Nirupam Roy
from IISc, Bangalore
14th October, 4:30 PM (IST)
He works in the field of Astrophysics and Cosmology and his research interest includes studies of the properties of the interstellar medium using radio observations. He is a very good speaker. We encourage all to attend the colloquium.
The abstract, the title is given below.
: Fire burn, and cauldron bubble
: Probing the Milky Way star formation and the interstellar medium using radio observations
: The interstellar medium, from which the new stars are born and to which the old stars inject matter and energy thereby enriching it, is indeed an integral and important component of the galaxies. Understanding the structure and evolution of the interstellar medium, that involves a diverse range of phenomena and a wide range of scales, is an interesting exercise. Multiwavelength observations, in particular, a few recent surveys of the Milky Way galactic plane at radio frequencies have revealed a few of these complex aspects. In this talk, I will present some interesting results showing how we can learn more about the multiphase interstellar medium and star formation from such studies.
Online Physics Seminar: Extreme-matter under the strongest magnetic fields in the universe, 14 August, 2020, 5:00 PM - 6:00 PM
Published on : 09-Aug-2020
We are hosting an online Physics seminar on Aug 14, 2020, by Prof. Victor Roy from NISER with the details below.
Title: Extreme-matter under the strongest magnetic fields in the universe.
Speaker: Prof. Victor Roy
Affiliation: NISER Bhubaneswar, India
Day/Date: Friday, Aug 14, 2020
Time: 17:00-18:00 Hrs (IST)
Abstract: Lorentz boosted heavy-ions produce the strongest magnetic fields in the universe in the collider experiments.
I will talk about some of the implications that we expect from such an unprecedented combination of matter under extreme temperatures and intense magnetic fields.
About the speaker:
Victor has been a faculty member in the School of Physical Science at NISER Bhubaneswar since 2016. Prior to that, he had been at Frankfurt University as an Alexander von Humboldt Postdoctoral fellow (2014-16) and at Hua-Zhong Normal Univ (2013-14). He obtained his Ph.D. degree from VECC Kolkata in 2012.
His area of research is Strong interaction Physics and Relativistic Heavy-ion Collisions with research interests on Numerical relativistic hydrodynamics and magnetohydrodynamics, Transport coefficients of Quark-Gluon Plasma, Relativistic Transport models and Electromagnetic field in high energy heavy-ion collisions.

Online Physics Colloquium : The Noise of Gravitons by Prof. Maulik Parikh, 10th August, 10.30 AM
Published on : 17-Jul-2020
We are organizing a colloquium (online via google meet) by Prof. Maulik Parikh from the Arizona State University on 10th August, 10:30 AM - 11:30 AM. (IST)
: The Noise of Gravitons
: If gravity is quantized, then gravitons exist. I will show that the bombardment of gravitons affects the motion of falling objects — by adding tiny fluctuations to their classical trajectories. Detection of these fluctuations (or “noise”) would provide evidence for the quantization of gravity and the existence of gravitons.

Black Hole Second Law from large D membranes
Published on : 10-Jan-2020
Dr. Arunabha Saha from the University of Geneva will be visiting us from 13th to 15th Jan 2020. He will be delivering a seminar on 14th January.
The details are:
Time and Venue:
2:30 PM- 3:30 PM, Block 6/203
Title: Black Hole Second Law from large $D$ membranes
I will discuss the duality between black hole dynamics and co-dimension one membranes in the limit of spacetime dimensionality tending to infinity. I will then use this duality to find an entropy current on the membrane world volume which captures the second law for the dual black hole in the Einstein -Gauss-Bonnet gravity. I will work up to the second subleading order in 1/D where the non-trivial entropy production starts. This analysis will be up to linear order in the Gauss-Bonnet parameter. I will also present some initial results for a non-perturbative analysis in the GB parameter up to leading order in 1/D.
Compact binary Coalescences: Constraints on waveforms
Published on : 09-Jan-2020
Mr. Neev Khera, who is a Ph.D. student at Penn State University will be visiting us on 16th January. He will be delivering a seminar on 16th, the details are:
Venue and Time: Block 5/203
, 4:00 PM - 5:00 PM
Title: Compact binary Coalescences: Constraints on waveforms
Abstract: Gravitational-wave detections of compact binary coalescences (CBCs) are reliant on accurate modeling. With upcoming future detectors, our models must improve by orders of magnitude. Exact general relativity applied to compact binary coalescences (CBCs) gives constraints that the waveforms must satisfy. These constraints can then be used as qualitatively new checks on the accuracy of waveform models. In this talk, we see the derivation of these constraints using the Bondi-Metzner-Sachs (BMS) group and its associated balance laws in the context of CBCs. We also see applications of this work in understanding the issue of angular momentum ambiguities for CBCs in general asymptotically flat spacetimes.
