A highlight of my childhood is the adventures of Professor Shonku, a timeless creation of Satyajit Ray. The first short story that tells the tale of the discovery of the diary of Professor Shonku is titled "Byom Yatrir Diary" that translates into the title of my blog. If you are reading this blog out of curiosity for how some fascinating functions for quantum entanglement and topological quantization were developed, then sit tight, you are in for a journey of a lifetime.

What I cannot code-up, I do not understand

There you go! Paraphrasing Richard Feynman-- done! Google Summer of Code -- done! I have gained valuable experience from the internship. Also, I hope to become a part of QuTiP soon. The title of this post more or less sums up my experience from the program. This will be a poor man's version of Feynman's dying quotes(on his blackboard!) "What I cannot create, I do not understand" "Know how to solve every problem that has been solved." With some awesome guidance from my mentors, I have been able to simulate some very well known concepts of lattice physics. Recreating a problem gives me an immense satisfaction as well as the confidence of understanding a problem inside out. I have never been in the elite bracket of physicists who can solve any problem on a piece of paper or a board. I am a computational person. So, to me redoing a problem means coding it up on a computer. I daresay, the list of problems that I believe to understand well has grown con...

The storm before the calm?

We are very close to the end! I need certain things to click. As I have come to learn, cracking the algorithmic part is a small part of the coding job. A code that produces accurate results have to withstand iterations of scrutiny, examination and cross-examination before it is given the green light. But, for me, the cracking part is the most crucial part. The project/functionality is made possible because an accurate code was produced, however 'unclean' and unscrutable. Everything hinges on that first breakthrough. I had to go over all the mathematics of Branch cuts in logarithmic functions to write a unfailing Chern number calculation routine. The most important functionality I want to add is the Chern number calculator function. This is not a simple calculation that can be done with any brute force way. It involves a intimate knowledge of branch cut of complex Logarithmic functions and also highlights the Gauge dependency of quantities in a Quantum problem. I am  havi...

A round peg in a round hole (Subject to Change!!)

At first, I did not think it necessary to add the "subject-to-change" clause at the end of the title, but now I know better! The process of first getting the correct functionality to actually convince the developers of QuTiP of the 'mergabilty'/readiness of the code is painstaking. Long before I managed to convince my mentors of the readiness of the code, I was able to get the codes to work and Writing codes for a popular simulation tool is much more demanding than writing codes for your research. My codes have already undergone a complete overhaul, almost everyday change, so as to make the code compatible with the spirit and soul of QuTiP. The science problem is only a fraction of the challenge. Finding the most convenient data structure and optimization philosophy is the . The code capability is crucially dependent on data structures and memory usage. I have had to spend a massive amount of time restructuring the code and developing documentation. Please ch...
