Hello there...
I am Titas Chanda, a theoretical physicist working as an Assistant Professor in the Department of Physics at the Indian Institute of Technology (IIT) Indore. I work on various topics related to Quantum Many-Body Physics, Quantum Simulations with ultra-cold atoms, Quantum Information Science, and more (for more details on my work please visit the Research page or drop a short mail at titas.chanda [AT] iiti.ac.in).
I am also the author of two open-source libraries:
(1) QIClib — A C++ (C++11 or later) library for general purpose quantum computing and quantum information.
(2) TenNetLib.jl — A tensor network library built on top of ITensors.jl for quantum many-body problems.

20/02 - 22/02/2024: Workshop on Quantum Simulators of the Future: From Dynamical Gauge Fields to Lattice Gauge Theories @ ICTP
The workshop has gathered world-leading groups that design, realize, and characterize a new generation of simulators with ultracold atoms and beyond. It has addressed novel quantum simulators of statistical gauge fields, dynamical lattices, and lattice gauge theory models (LGT), as well as connections to quantum computing and tensor network methods.

02/01/2024: Publication in Physical Review B
Our paper "Spectral properties of the critical (1+1)-dimensional Abelian-Higgs model" by Titas Chanda, Marcello Dalmonte, Maciej Lewenstein, Jakub Zakrzewski, and Luca Tagliacozzo has been published in Physical Review B.
30/12/2023: Introducing TenNetLib.jl
Excited to introduce TenNetLib.jl, a tensor network library built on top of ITensors.jl for quantum many-body problems. TenNetLib.jl features widely-used tensor network codes, designed with a multi-layered abstraction to cater to diverse user needs. The library provides users with varying levels of control over their computations. Currently, TenNetLib.jl presents an array of functionalities for:
(a) Finite-size Matrix-Product States (MPS): Different variants of Density Matrix Renormalization Group (DMRG) and Time Dependent Variational Principle (TDVP) (including subspace expansion) methods.
(b) Tree Tensor Network (TTN): Variational search for the ground state and first few excited states.
The source code for TenNetLib.jl can be found on GitHub.
The documentation for TenNetLib.jl can be found here.
