Query: Kalb-Ramond field induced cosmological bounce in generalized
  teleparallel gravity   In this paper, we consider the Kalb-Ramond (KR) field and its effects in the
context of generalized teleparallel gravity in 3+1 dimensions. Teleparallel
gravity is a description of gravitation in which the torsion arising from
fields with spin are accommodated naturally as field strength tensor of the
non-trivial tetrads. In order to describe the coupling prescription, we address
the correct generalization of the Fock-Ivanenko derivative operator (FIDO) for
an n-form tensor field. By varying with respect to the non-trivial tetrads,
this rank-2 field is shown to source the teleparallel equivalent of Einstein's
equations. We then study the possibility of reproducing two well-known
cosmological bounce scenarios, namely, symmetric bounce and matter bounce in
four-dimensional space-time with FLRW metric and observe that the solution
requires the KR field energy density to be localized near the bounce. This
feature could, in turn, explain the lack of experimental evidence in detecting
the rank-2 field in the present-day universe. Furthermore, we compute the
analytical expression for modifying the teleparallel gravity and energy density
of the KR field for the bounce scenarios.
