Title: Free, Higher Derivative Scalar Field Drives Quantum Phase Transition

Abstract:

We explicitly show that sixth order spatial derivative, Lorentz symmetry
violating term in two dimensional space leads to quantum phase transition.
We show that around the critical point, the number of zero modes increase
dramatically that catalyze the change in the ground state property of the
many-body wave function. We extend the analysis to three dimensional
cylindrical geometry and show that the entanglement heat-capacity has
similar profile to the heat capacity measurements of high temperature
superconductors. We explicitly show that the long-range interaction in the
two dimensional surface explain key features of high temperature superconductors.
