    • Characteristic temperatures of a triplon system of dimerized quantum magnets 

      Rakhimov, Abdulla; Nishonov, M.; Rani, Luxmi; Tanatar, Bilal (World Scientific Publishing Co. Pte. Ltd., 2021)
      Exploiting the analogy between ultracold atomic gases and the system of triplons, we study magneto-thermodynamic properties of dimerized quantum magnets in the framework of Bose–Einstein condensation (BEC). Particularly, ...

    • Nonequilibrium electron relaxation in graphene 

      Rani, Luxmi; Bhalla, P.; Singh, N. (World Scientific Publishing, 2019)
      We apply memory function formalism to investigate nonequilibrium electron relaxation in graphene. Within the premises of two-temperature model (TTM), explicit expressions of the imaginary part of the memory function or ...

    • A novel effect of Electron Spin Resonance on electrical resistivity 

      Singh, N.; Rani, Luxmi (Elsevier, 2018)
      We extend the well known phenomenon of magnetoresistance (extra resistivity of materials in transverse magnetic field) to a regime where in addition to a transverse magnetic field, a transverse microwave field of resonant ...

    • Spin-gapped magnets with weak anisotropies I: Constraints on the phase of the condensate wave function 

      Rakhimov, Abdulla; Khudoyberdiev, A.; Rani, Luxmi; Tanatar, Bilal (Elsevier, 2020-11-27)
      We study the thermodynamic properties of dimerized spin-gapped quantum magnets with and without exchange anisotropy (EA) and Dzyaloshinsky and Moriya (DM) anisotropies within the mean-field approximation (MFA). For this ...
