  • PT-symmetric dimer of coupled nonlinear oscillators 
    KHARE, AVINASH (Indian Academy of Sciences, 2015-11)
    We provide a systematic analysis of a prototypical nonlinear oscillator system respecting PT-symmetry, i.e., one of them has gain and the other an equal and opposite amount of loss. We first discuss various symmetries of ...
  • Phases of the hard-plate lattice gas on a three-dimensional cubic lattice 
    Mandal, Dipanjan; Rakala, Geet; Damle, Kedar; DHAR, DEEPAK; Rajesh, R. (American Physical Society, 2023-06)
    We study the phase diagram of a lattice gas of 2×2×1 hard plates on the three-dimensional cubic lattice. Each plate covers an elementary plaquette of the cubic lattice, with the constraint that a site can belong to utmost ...
