I am Adithya...

... and I am a physicist.

My research interest is in high-energy physics.

I am specifically interested in theoretical studies of Quantum Field Theories, and also in how these studies can benefit from computational (both classical and quantum) techniques, which means I am interested in Lattice Simulation of Gauge Theories and studies of Quantum Field Theories mapped to Spin-Lattice Systems too.

I received my masters' degree in 2024 from NIT Surat, India, where I worked with Laurent Baulieu from Sorbonne University on my master's thesis on Quantum Gauge Field theories.

Prior to that, I have also worked as a research intern at various places, including a DAAD-WISE project at Jena in Germany on Lattice Simulations, and various eminent Indian institutes like TIFR, IISc, PRL, etc.
RESEARCH
Quantum Field Theories describe the dynamics of theories with fields, whose excitations manifest as particles. In simple words, what a field theory does is assign some elements (scalars, vectors, spinors) to each point in space, and study their dynamics with time. They were born out of the inadequacy of quantum mechanics in explaining relativistic processes where particles were created and annihilated. Despite their tremendous success, QFTs still harbor deep mysteries—most notably how to quantize gravity, which is one of the biggest unsolved questions in modern physics. Most of these problems can be attributed to the fact that QFTs are inherently complicated, since they start off assuming infinite number of degrees of freedom, i.e. one mathematical object to each and every point in spacetime (which is, not so obviously, infinite).

My research is in theoretical ventures into QFTs and their relatives, in a hope to stumble upon some problem and solve it someday. For my master's thesis, I studied a very specific problem in quantum gauge theories (where for each point in space time, the field assigns a vector) called the Gribov Problem.

Another aspect I find interesting is that one can discretize spacetime points to reduce the number of degrees of freedom from infinite to finite, and formulate a QFT on this discrete "lattice". Once put on a lattice, one can use modern computational facilities to compute the hard integrals to get numerical results which can be compared with experiments. This is called lattice field theory (see Wilson for more details).

More interestingly, in recent days, there has been a formulation of a mapping between the interactions of qubits to the dynamics of lattice field theories. Exploiting these correspondences could allow us to simulate lattice field theories directly on quantum computers (for example, Muschik et. al.), opening a new frontier at the intersection of quantum information and high-energy physics.

Interactive Exploration

I have developed a few webpages for exploring concepts like Monte-Carlo simulations and Hopfield Networks interactively. Check them out at /blog (you can filter them using t:interactive).

Creative Corner

Sometime you can find me sketching too! You can find a few of my sketches at /art
I also love web-designing (which I do mostly with pure CSS/JS!). A few previous iterations (not updated) of my website are here:
Click here for the most recent one and here for a bit older one. The older one took a lot of sweat and soil! But was dumped at the end due to it being not relevant to an academic setting... Since I gave up on that iteration, the older one is also not optimized for mobile devices!
I have also created the website for the Physics Club of NIT Surat. Give it a visit at physicsclubsvnit.github.io

Science Communication

Articles:
I believe in science for all, and therefore I have contributed some articles to thehavok.com aimed at making science accessible to all. You can read those articles at here
