Barrow Holographic Dark Energy with a Ricci Cutoff in Power-Law $f(Q,L_m)$ Gravity: Late-Time Cosmological Dynamicstranslating…

arXiv:2609.01629v1 Announce Type: new Abstract: We investigate late-time Barrow holographic dark energy (BHDE) with Ricci cutoff in $f(Q,L_m)=Q+\alpha Q^n-2L_m$ gravity. The $Q^n$ term modifies the symmetric-teleparallel geometry, while $\Delta$ deforms holographic energy via…
