Quantum Materials & Low-Dimensional Nanoelectronics

About

I'm an early-stage independent researcher from Bangladesh, passionate about quantum materials and nanoscale phenomena. My work aims to understand the physical properties of nanomaterials through first-principles calculations, exploring how atomically thin structures can lead to new opportunities in electronics, photonics, and information functionalities.

I'm particularly interested in how spins, light, and topology interconnect at the subatomic level, and how we can harness these aspects for future technologies.

Research Interests

Current Focus

  • Spin-dynamics in low-dimensional materials (2D monolayers, quantum dots, TM-based compounds)
  • Nonlinear optics in noncentrosymmetric systems
  • Density Functional Theory (DFT) and computational physics methods
  • Doping, defects, and surface-induced disorder in 2D flakes

Future Directions

  • Real-space topological features of confined materials
  • Cavity quantum electrodynamics and spin–photon interactions via QED-DFT methods

Influential Books

Molecular Quantum Mechanics

Atkins & Friedman

Built my foundational understanding of atomic-level interactions and approximation theories. Key concepts applied in my research.

Quantum Transport: Atom to Transistor

Supriyo Datta

My introduction to NEGF theory. Chosen for its precise explanations, abundant figures, and intuitive approach to transport properties.

Topological Quantum Materials

Grigory Tkachov
