Hello ! I'm Jai. This page advertises some of my (hopefully creative or informative) write-ups. I enjoy doing this as a hobby, because the best part about writing is that I don't have to keep those ideas in mind ever after.
Quantum Dots have been made to act as efficient single-photon or multi-photon emitters. Basically this means we can develop some kind of microscopy called SWIR (short wavelngth enfrared spectroscopy). The paper demonstrates this technique, including a brief mention of the quantum dot technology. I wrote this article to discuss the physics aspect of the work, besides discussing the application to non-invasive imaging of tumour in the brains of mice. (April 20, 2024)
Almost a year after I started penning down what kind of questions does my passion for crafting algorithms for quantum technologies, and fusing them with semiconductor manufacturing, to actualize their effectiveness in the realms of neuro-technology and subterranean imaging, lead me to ask, I finally have these charted on this page. It's the first of my blogs on Brain-Computer Interfacing and Subterranean-Tomography. Much of the focus is on the fundamental enquiries that need to be made, from my point of view. I have not discussed the state of the art technologies developed to answer these questions. I will do that in a future post.(April 17, 2024)
Quite recently, I thought of an innovation which we could use to image the mantle and possibly the core of the Earth and extraterrestrial objects. Here's my write-up on it. (September 8, 2023)
Around the middle of the 20th century, two chums from California in their late 30s, none other than the influential writer on human nature - John Steinbeck, and the marine-biologist Ed Ricketts, set out on an expedition in the Gulf of California. John spent most of his writing career in California. Ed had established a laboratory in Monterrey, California which was a storehouse and supply source of marine specimens. Keen on getting respite from the war, their expedition, as narrated by John in his book `The Log from the Sea of Cortez´, is full of philosophical ponderings from both of them, whenever they are not scouring for critters. Some of my favourite narrations are cataloged in this page, in red, with their context whenever necessary. These had quite a deep impact on me while I was reading the book. (June 29, 2023)
Recently, I discovered one of what excites me to think of the Sahara - a massive desert in North Africa. Might take up a significant portion of a lifetime to embark on this journey. I decided to write a page on it. (17th June 2023)
I’d like to share something about this wonderful book, having opened my mind on the issue of global warming. There is NO alternative to fighting global warming than aiming for "zero carbon emissions" by 2050. That is the deadline. Tremendous innovations in technology are needed, along with changes in laws, tax policies and funding research in this sector. It is a must-read for all present and prospective fellow engineers, scientists, physicists, there is huge scope of innovations needed from almost all fields of engineering (electrical, climate, nuclear, physics, computers, agricultural, chemical, energy, biosciences, environmental) in order to fight global warming, that is all listed in this book.

Automated plant watering system -
Those of y'all having plants at home, I'm sure you must've been bothered by the idea of watering them while you're away from home. I've got you covered here. Check out this video. Here's a detailed report of the project if you are interested in building one by yourself. (30th October 2021)

On April 10, 2019 the Event Horizon Telescope published the first ever observed image of a Black Hole at the nucleus of M87 spiral galaxy in the Virgo cluster. Here is a presentation I gave on preliminary observations that were made by the EHT group. It serves an impetus to what aspects of this observation our Black Hole Super-radiance team wishes to do further research in. Two problems we have decided to attack are plasma surrounding the event horizon and existence of axionic fields in this conformal spacetime. (8th July 2021)
Weeks of teamwork and collaboration led us to a successful presentation on quantum-photonic bound states. First, we deal with an electron toy-model and look at the bound states in the continuum for a one-dimensional quantum potential well. We then exploit the one-to-one correspondence between electronic spin and polarisation states of light and develop the theory corresponding to bound states in the continuum for a one-dimensional photonic system, which consists of one-dimensional photonic crystal conjugated with a liquid-crystalline defect layer and covered by metal film. We perform numerical calculations and plot graphs of physical quantities of interest for both these systems. (12th April 2021)

After all, we do contain Prometheus' fire stolen from Zeus. Today, I finally completed reading 20000 Leagues under the Sea - one of the most exciting novels I've ever read. Captain Nemo, a man who is tired of mankind (or has been wronged, who knows) retires land and lives in the unexplored element, water. He finds solace underwater, at the utmost depths, hunting sharks, studying marine life, pearl fishing, discovering intercontinental tunnels, having found Atlantis but keeping it privy to himself, scavenging shipwrecks and playing the organ. All this in a perfectly-engineered submarine having a huge library, an enormous store of seafood, treasure of uncountable worth, yet, Captain Nemo lives like a man primitive to his time. Despite his inextiguishable hatred for who knows whom, he is prudent in living and shows compassion for the shipwrecked naturalist Professor Jean Arronax. (10th Feb 2021)
I made this presentation today in the Quantum Mechanics class, demostrating quantum tunnelling in the trigonal pyramidal Ammonia molecule, when the Nitrogen atom tends to flip from "Up state" to "Down state" and vice versa. Classicaly, flipping is impermissible due to a large energy barrier across the Hydrogen plane. But Quantum mechanically, not only does this flipping occur but also leads to the formation of two degenerate energy states for the Ammonia Molecule, out of which one is more stable than the other! I've made a few slides on this phenomenon. (5th Feb 2021)
