TL;DR
This paper explores how a Dirac field interacts with a specific three-dimensional gravity model, finding solutions that persist even without a cosmological constant, which could impact understanding of quantum gravity.
Contribution
It introduces cosmological solutions for a Dirac field coupled to the Mielke-Baekler gravity model, including solutions valid at zero cosmological constant.
Findings
Existence of solutions with a Dirac field in the Mielke-Baekler model
Solutions remain valid when the cosmological constant approaches zero
Provides new insights into fermionic fields in lower-dimensional gravity
Abstract
We consider a Dirac field coupled minimally to the Mielke-Baekler model of gravity and investigate cosmological solutions in three dimensions. We arrive at a family of solutions which exists even in the limit of vanishing cosmological constant.
