Contribution
It clarifies the high temperature phase recovery and the construction of emergent bulk spacetime using bi-local representation in thermo field dynamics.
Findings
Identification of evanescent modes in the bulk construction
Analysis of spin mixing at finite temperature
Insights into the high temperature phase and gauging in O(N) theory
Abstract
We study the Large dynamics of the field theory in the Thermo field dynamics approach. The question of recovering the high temperature phase and the corresponding gauging is clarified. Through the associated bi-local representation we discuss the emergent bulk space-time and construction of (Higher spin) fields. We note the presence of `evanescent' modes in this construction and also the mixing of spins at finite temperature.
