Welcome to the web page of Computational Quantum Many Body Physics lab at NIT Jalandhar.
The theoretical condensed matter group of Dr. Vinod Ashokan is involved in research in three main areas:
1. Quantum Liquids,
2. Strongly Correlated Systems,
3. Nanomagnetism & Magnonics
The study of quantum fluids and the effect of the quantum many-body correlations between the identical fermions and bosons are intriguing problems in condensed matter physics. These systems have fascinated physicists because of a variety of interesting phenomena with anomalous properties, and applications in nanoelectronics, sensors, quantum information processing and bio-medical applications. The quantum fluids include the systems of bosons (liquid 4He, ultra cold atomic gases, etc.), which exhibit the Bose-Einstein condensation (BEC), and fermion such as liquid Helium 3He, electrons in metals, semiconductors, etc.). Even after several years of rigorous research of the subject and advancements in computational physics, the exact way to treat the strong correlation effects of many-particle interactions is still an open problem. These strong correlations cannot be described accurately by mean-field theories, independent-particle pictures, the perturbative treatments, or by the theories of Hartree, Hartree and Fock which do not take into account the correlations. The idea of neglecting the correlations between electrons in metals prevailed for a long time until the problems of strongly correlated electron systems were encountered. Not all fermion liquids conform to Landau's paradigm. There are several problems of current interest that cannot be explained by this theory. Some of them are high-temperature superconductivity, fractional quantum Hall effect , strongly correlated one-dimensional (1D) electron systems, etc. The department of physics Lab of Computational Quantum Many body Physics involved in research focuses on both fundamental and applied problems in condensed matter physics. We had made a distinct contributions in our understanding of structure and dynamics of quantum liquids, including electron correlation effects in Coulomb systems of homogeneous electron gas in 1D.
