• Bosonic quantum Hall states in single-layer two-dimensional optical lattices 

  Bai, Rukmani; Bandyopadhyay, Soumik; Pal, Sukla; Suthar, K.; Angom, D. (American Physical Society, 2018-08)

  Quantum Hall (QH) states of two-dimensional (2D) single-layer optical lattices are examined using the Bose-Hubbard model (BHM) in the presence of an artificial gauge field. We study the QH states of both the homogeneous ...
• Fluctuation driven topological transition of binary condensates in optical lattices 

  Suthar, Kishan; Roy, Arko; Angom, D. (Cornell University Library, 2014-11)

  We show the emergence of a third Goldstone mode in binary condensates at the phase-separation in quasi-1D optical lattices. We develop the coupled discrete nonlinear Schr\"odinger equations (DNLSEs) using Hartree-Fock-Bogoliubov ...
• Thermal fluctuations enhanced miscibility of binary condensates in optical lattices 

  Suthar, Kuldeep; Angom, D. (Cornell University Library, 2016-08)

  We examine the role of thermal fluctuations in two-species Bose-Einstein condensates confined in quasi-two-dimensional (quasi-2D) optical lattices using the Hartree-Fock-Bogoliubov theory with the Popov approximation. The ...
