Talk on the ‘boundary dual of Fixed area states’ by Research Scholar Baishali Roy on 23 Feb 2022

Speaker: Baishali Roy – B1950021 (research scholar, Dept. of Physics, RKMVERI) Date: 23/02/2022, Time 4 pm External Expert: Prof. Koushik Ray, IACS, Kolkata Abstract After the discovery of AdS/CFT conjecture, one of the main goals has been to find the ‘dictionary’ between the theories on two sides. Recently, an interesting set of states called the fixed area state (FAS) have been discussed in the literature. These are defined in the bulk via a gravitational path integral, where the bulk gravitational fluctuations on the Read More...

Talk on ‘Chaos in periodically driven CFTs’ by research scholar Somnath Porey on 17 Feb 2022

Speaker: Somnath Porey – B1950020 (research scholar, Dept. of Physics, RKMVERI) Date: 17/02/2022, Time 4 pm Venue: Dept. of Physics, Prajna, Bhavan External Expert: Prof. Koushik Ray, IACS, Kolkata Abstract Out-Of-Time-Ordered-Correlation functions (OTOCs) in thermal equilibrium has been used as a diagnostic of chaos in QFTs for times much smaller than the “scrambling time”.  In this talk, we will argue that the OTOCs continue to be a good diagnostic of chaos even when the system is out of equilibrium. As an explicit example, we Read More...

Talk on ‘Brainwave entrainment’ by Punit Parmananda, IIT Bombay – 22 January 2020

Prof. Punit Parmananda from IIT Bombay would be delivering a talk on ‘Brainwave entrainment’ on 22th January 2020 at 3:30 pm. All the students and faculty are invited to the talk. Venue Saradananda Seminar Hall, Prajna Bhavan, RKMVERI Belur Campus Abstract The phenomenon of the entrainment of human brainwaves to a predetermined aperiodic stimulus is endeavored. Initially, the periodic entrainment of the brainwaves was studied using two different stimuli in the form of periodic auditory and visual signals. The entrainment with the periodic visual Read More...

Talk on ‘Energy cascade in internal wave attractors’ by Thierry Dauxois, ENS de Lyon & CNRS, France – 24 January 2020

Prof. Thierry Dauxois from Ecole Normale Supérieure (ENS) de Lyon & CNRS, France would be delivering a talk on ‘Energy cascade in internal wave attractors’ on 24th January 2020 at 2:30 pm. All the students and faculty are invited to the talk. Venue Saradananda Seminar Hall, Prajna Bhavan, RKMVERI Belur Campus Abstract Internal gravity waves play a primary role in geophysical fluids: they contribute significantly to mixing in the ocean and redistribute energy and momentum in the middle atmosphere. In addition to their very interesting Read More...

Talk on ‘Collective 1/f fluctuations by pseudo-Casimir-invariants’ by Prof. Yoshiyuki Yamaguchi, Kyoto University – 14th August 2019

Prof. Yoshiyuki Yamaguchi from Kyoto University, Japan would be delivering a talk on ‘Collective 1/f fluctuations by pseudo-Casimir-invariants’ on 14th August 2019 at 3.15 PM. All the students and faculty are invited to the talk. Venue: Saradananda Seminar Hall, Prajna Bhavan, RKMVERI Belur Campus Abstract The 1/f fluctuation is ubiquitously observed in nature and has attracted general interest over the past few decades. In this talk, we concentrate on collective motion in Hamiltonian systems with many degrees of freedom under long-range interaction, such as Read More...
