In-in formalism with resummmation in a constant electric field: propagators including nontrivial boundary wavefunctions
Kenji Fukushima, Shuhei Minato
We present the derivation of an alternative representation of the real-time in-in formalism under a spatially homogeneous and time independent electric field. Because the system ex…
QCD Phase Diagram and Astrophysical Implications
Kenji Fukushima
I make a brief review about the QCD phases and the equation of state inferred from the neutron star data. Along the temperature axis at low baryon density, the QCD phase transition…
Understanding Diffusion Models by Feynman's Path Integral
Yuji Hirono, Akinori Tanaka, Kenji Fukushima
Score-based diffusion models have proven effective in image generation and have gained widespread usage; however, the underlying factors contributing to the performance disparity b…
Toward understanding the lattice QCD results from the strong coupling analysis
Kenji Fukushima
This is a review of strong coupling approaches to grasp the nature of the phase transition in finite temperature and density QCD. We commence with classics of the center symmetry a…
