Lorenz Gauge Fixing of $f(T)$ Teleparallel Cosmology

Understand

In teleparallel gravity, we apply Lorenz type gauge fixing to cope with redundant degrees of freedom in the vierbein field.

• This condition is mainly to restore the Lorentz symmetry of the teleparallel torsion scalar.
• In cosmological application, this technique provides standard cosmology, turnaround, bounce or $\Lambda$CDM as separate scenarios.
• We reconstruct the $f(T)$ gravity which generates these models.
