Query: Exploring Novel Quantum Criticality in Strained Graphene   Strain tuning is increasingly being recognized as a clean tuning parameter to
induce novel behavior in quantum matter. Motivated by the possibility of
straining graphene up to $20$ percent, we investigate novel quantum criticality
due to interplay between strain-induced anisotropic band structure and critical
antiferromagnetic spin fluctuations (AFSF) in this setting. We detail how this
interplay drives $(i)$ a quantum phase transition (QPT) between the
Dirac-semimetal-incoherent pseudogapped metal-correlated insulator as a
function of strain ($\epsilon$), and $(ii)$ critical AFSF-driven divergent
nematic susceptibility near critical strain ($\epsilon_{c}$) manifesting as
critical singularities in magneto-thermal expansion and Gr\"uneisen
co-efficients. The correlated band insulator at large strain affords
realization of a two-dimensional dimerized spin-singlet state due to this
interplay, and we argue how doping such an insulator can lead to a spin-charge
separated metal, leading to anomalous metallicity and possible unconventional
superconductivity. On a wider front, our work serves to illustrate the range of
novel states realizable by strain-tuning quantum materials.
