Title: “Material Training: Success, Failure, and Improvement through geometrical constraints”

Title:

Training materials through periodic drive allows endowing materials to explore the high dimensional space of structures to exhibit desired elastic functions. However, increasing the complexity of the desired response results in ultra-slow convergence of training error and a transition occurs from trainable phase to untrainable phase. Approaching the critical threshold of complexity, low-frequency modes of vibrational properties proliferate and creep down to zero frequency implying that training causes material degradation. We show that the excess low-frequency spectrum is due to atypical local structures. We also show that by imposing geometrical constraints on material structure the degradation can be avoidable, and training can be improved in termsof convergence, capacity, and robustness of training.

Title: Quantum Matter and the Age of Entanglement Speaker: Dr. Siddhartha Lal Affiliation: Associate Professor, Department of Physical Sciences, IISER Kolkata

Venue: Kanada Auditorium

Time: 2:30PM

Coffee/Tea: 2:20PM

Abstract: There is great activity at present all over the world towards developing quantum technologies. But what is the basic physics that drives this activity? Why are we searching for novel quantum materials, and building noise-free quantum computers? Where does my research fit in with all of this? In presenting some answers, I will focus on how the concept of entanglement - a feature that is unique to the quantum world - of an interacting many-particle quantum system holds the key to next-generation quantum technologies. I will also offer some insights on results we have obtained recently on the entanglement encoded within a few different examples of strongly interacting quantum matter.

On Friday 28th April 2023, Prof G.U. Kulkarni, President JNCASR inaugurated a new facility at Jakkur campus which provides improved amenities to contractual staff members working under Housekeeping Horticulture and for those engaged through outsource agencies. This facility includes improved drinking water facility, place for recreation, restrooms, changing room etc for these employees.

Administrative Officer along with other officers and staff members attended this event.

Title: Towards simulating fluid flows on quantum computers

The month-long sports celebration - Khel Utsav 2023 began atJNCASR on 17 April 2023 with great enthusiasm and cheers of JNCASR community!

Lined up with exciting sports viz football, volleyball, cricket many more. The event was inaugurated by Prof. G.U. Kulkarni President, JNCASR.

On the occasion of International Women’s Day, a five km Run was organized by JNCASR to celebrate the Annual Marathon on 5th March 2023. More than hundred members of the JNCASR community including Students, Professors, and Staff members participated enthusiastically in this mini marathon and everyone successfully completed the run.

Title:Developing adaptable systems using patterns

Date and Time: 01 March 2023 (Wednesday) at 03:15 pm(Tea/Coffee: 03:00 pm)

Venue:AMRL Conference Hall, JNCASR [Hybrid Mode]

Abstract:

In this talk we will discuss two instances of systems that adapt to local changes in their environment thus providing it with particular function. In the first part we briefly describe how elastic materials deform under external or internal body forces and result in instabilities that dramatically modify their morphology. We will then see the mechanism behind a new class of geometric materials that bypasses these instabilities and the role of softness in determining their properties for shape morphing applications. In the second part we will discuss ways by which patterns in natural systems can inspire robotic systems for a particular function and examine a particular instance of collective task execution in ants. We will then look at a possible generalized approach to design robotic systems with robustness that leverages the pattern formation paradigm.
