Dr. Sudip Kumar Haldar

Biography

Dr. Sudip Kumar Haldar joined JIIT, Noida as an Assistant Professor (Grade II) in June 2023. Prior to joining JIIT he has worked as an Assistant Professor in SRM University Delhi-NCR and as a postdoctoral fellow in University of Haifa, Israel (jointly with Technion - Israel Institute of Technology, Haifa, Israel) and in Physical Research Laboratory, Ahmedabad. He obtained his PhD in theoretical physics in 2015 from University of Calcutta, Kolkata. He qualified in CSIR-NET JRF (2009), GATE (2009) and JAM (2006). His present research interest is quantum many-body systems and its application in quantum information & computation (QIC). He has successfully completed one sponsored project funded by DST-SERB, Govt. Of India. He has authored more than 20 research papers in peer reviewed journals such as Physical Review A, Scientific Reports, and New Journal of Physics.

Educational Qualifications

Ph.D.

Research Highlights

Dr Haldar works on ultra-cold atoms and other quantum many-body systems and its application in quantum information & computation (QIC).

Ultra-cold atoms is a paradigmatic system for studying quantum many-body effects. Due to recent advances in the experimental techniques it has become possible to control the system parameters very efficiently. This led to simulating several condensed matter systems such as lattice with a greater control. Such simulation of condensed matter systems is often referred to as analog quantum computing. Such systems are also potential candidate for building quantum computers. This necessitates deeper understanding of such systems with finer details which cannot be captured with the commonly employed mean-field theory. Accordingly, a numerically exact many-body techniques, called the Multi-configuration time dependent Hartee method for bosons (MCTDHB), was developed by the Haifa group of Prof Ofir E Alon. Dr Haldar, as part of this group, is actively engaged in further development and applications of MCTDHB for understanding experimentally relevant ultra-cold atomic systems. 

Additionally, Dr Haldar is also interested in studying various quantum characteristics such as bipartite and multipartite entanglement, quantum correlations in spin models which can also be realised with ultra-cold atomic systems. This is well known that entanglement is a key resource for quantum technology. Accordingly, he is interested to find optimum ways to generate, control, and preserve bipartite and multipartite entanglement, quantum correlations, independence of entanglement. Further, he is also interested to address some of the fundamental issues such as quantum phase transitions by exploring quantum information concepts.
