Bikas Kanta Chakrabarti (born 14 December 1952 in Kolkata (erstwhile Calcutta) is an Indian physicist.[1] At present he is INSA Scientist (Physics) at the Saha Institute of Nuclear Physics & Visiting Professor (Economics) at the Indian Statistical Institute, Kolkata, India.

Biography

[edit]

Chakrabarti received his Ph.D. degree from Calcutta University in 1979. Following post-doctoral work at the University of Oxford and the University of Cologne, he joined the faculty of Saha Institute of Nuclear Physics (SINP) in 1983. He is S. S. Bhatnagar Prize awardee (1997) and former J. C. Bose National Fellow (2011-2020). He is a former director of SINP. At present he is INSA Scientist at SINP (2021-) and also Honorary Visiting Professor of economics (2007-) at the Indian Statistical Institute. Emeritus Professor of SINP and of S.N. Bose National Centre for Basic Sciences. Much of Chakrabarti's research has centered around statistical condensed matter physics (including Quantum annealing; see also D-Wave Systems & Timeline of quantum computing) and applications to social sciences (see e.g., Econophysics).

Topic: Quantum annealing

[edit]
  • "Idea of Quantum annealing” due to "tunnelling through infinitely high classical barriers separating infinitely many metastable states was indeed put forward even earlier, in Ray, Charabarti & Chakrabarti, Phys. Rev. B (1989)"(4th para, Introduction),[3] Journal of Physics A Topical Review by Erio Tosatti et al. from ICTP, Trieste (2008)
  • "Quantum annealing [Finnila et al. Chem. Phys. Letts. (1994); Kadowaki & Nishimori, Phys. Rev. E (1998); Farhi et al., arXiv (2002); Brooke et al., Science (1999); Santoro et al., Science (2002)] is a technique inspired by classical simulated annealing [Ray, Chakrabarti & Chakrabarti, Phys. Rev. B (1989)] that aims to take advantage of quantum tunnelling." [1st sentence],[5] Nature Communications by Sergio Boixo, Hartmut Neven (Google California) et al. (2016)
  • "Quantum annealing aims at finding low-energy configurations ... by a controlled quantum adiabatic evolution ... to escape local minima through multiple tunneling events (Ray, Charabarti & Chakrabarti, Phys. Rev. B (1989); ...; Das & Chakrabarti, Rev. Mod. Phys. (2008))" (1st sentence) ... [It can] lead to extremely powerful alternative computational devices (3rd sentence),[6] PNAS by Riccardo Zecchina et al., ICTP Trieste (2018)
  • “Adiabatic quantum computation (Farhi et al., Science, 2001; Das & Chakrabarti, Rev. Mod. Phys., 2008)” (Abstract) ...“has attracted intense interest (Das & Chakrabarti, Rev. Mod. Phys., 2008; Farhi et al., Science, 2001) owing to its potential speedup over classical algorithms” (Introduction),[8] PNAS by Frank Wilczek et al. from MIT & elsewhere (2023)
  • "Quantum annealing ... garnered increasing interest because of their quantum attributes that could offer potential solutions to the challenges inherent in combinatorial optimization problems [Ray, Chakrabarti & Chakrabarti, Phys. Rev. B (1989); Finnila et al., Chem. Phys. Lett. (1994); Kadwaki & Nishimori, Phys. Rev. E (1998); Farhi et al., Science (2001); ...] ... D-wave systems [Johnson, et al., Nature (2011); King et al., Nature (2018)] ... utilize superconducting quantum interferometers [Kadwaki & Nishimori, Phys. Rev. E (1998); Brooke et al., Science (1999), Das & Chakrabarti, Rev. Mod. Phys, (2008)] to execute quantum annealing ..." [Introduction, 1st & 2nd para],[9] write Yoshihisa Yamamoto (Stanford University) et al., in their IEEE Access (2024)

Topic: Econophysics

Eugene Stanley (2022)
  • “Econophysics: An Introduction (Sinha, Chatterjee, Chakraborti & Chakrabarti, Wiley, 2010)” has been the only suggested Textbook for the Econophysics course,[14] offered (Teacher: Diego Garlaschelli) for last one & half a decade by the Leiden University physics dept. (where the inaugural-year [1969] economics Nobel Laureate Jan Tinbergen did undergrad and Ph. D. in statistical physics of economy under Paul Ehrenfest) (course began 2012-2013 & is continued: 2024-2025)
