Query: High-Temperature Criticality in Strongly Constrained Quantum Systems   The exotic nature of many strongly correlated materials at reasonably high
temperatures, for instance cuprate superconductors in their normal state, has
lead to the suggestion that such behavior occurs within a quantum critical
region where the physics is controlled by the influence of a phase transition
down at zero temperature. Such a scenario can be thought of as a bottom-up
approach, with the zero temperature mechanisms finding a way to manifest
critical behavior at high temperatures. Here we propose an alternative,
top-down, mechanism by which strong kinematic constraints that can only be
broken at extremely high temperatures are responsible for critical behavior at
intermediate but still high temperatures. This critical behavior may extend all
the way down to zero temperature, but this outcome is not one of necessity, and
the system may order at low temperatures. We provide explicit examples of such
high-temperature criticality when additional strong interactions are introduced
in quantum Heisenberg, transverse field Ising, and some bosonic lattice models.
