  Non-Fermi liquid behavior and pseudogap formation are among the most
well-known examples of exotic spectral features observed in several strongly
correlated materials such as the hole-doped cuprates, nickelates, iridates,
ruthenates, ferropnictides, doped Mott organics, transition metal
dichalcogenides, heavy fermions, d- and f- electron metals, etc. We demonstrate
that these features are inevitable consequences when fermions couple to an
unconventional Bose metal [1] mean field consisting of lower-dimensional
coherence. Not only do we find both exotic phenomena, but also a host of other
features that have been observed e.g. in the cuprates including nodal
anti-nodal dichotomy and pseudogap asymmetry(symmetry) in momentum(real) space.
Obtaining these exotic and heretofore mysterious phenomena via a mean field
offers a simple, universal, and therefore widely applicable explanation for
their ubiquitous empirical appearance.
