Mean field theory for strongly coupled systems: Holographic approach
In this paper, we develop the holographic mean field theory for strongly interacting fermion systems. We investigate various types of the...

Breakdown of field theory in near-horizon regions
We discuss back-reaction in the semiclassical treatment of quantum fields near a black hole. When the state deviates significantly from...

U(1) quasi-hydrodynamics: Schwinger-Keldysh effective field theory and holography
We study the quasi-hydrodynamics of a system with a softly broken U(1) global symmetry using effective field theory (EFT) and holographic methods. In...

Spin supplementary condition in quantum field theory: covariant SSC and physical state projection
The spin supplementary conditions are constraints on spin degrees of freedom in classical relativity which restricts physical degrees of freedom to...

Perturbative expansions and the foundations of quantum field theory
Perturbative expansions have played a peculiarly central role in quantum field theory, not only in extracting empirical predictions but also in...

Perturbative effective field theory expansions for cosmological phase transitions
Guided by previous non-perturbative lattice simulations of a two-step electroweak phase transition, we reformulate the perturbative analysis of...

Electromagnetic field theory in superluminal spacetime
Recently, a number of experimental observations on the superluminal group velocities of pulses propagating in dispersive media have led to...

The new formulation of higgs effective field Theory
We present the explicit construction of the effective field theory (EFT) of standard model mass eigenstates. The EFT, which is invariant under U(1) e.m....

An algebraic formula for two loop renormalization of scalar quantum field theory
We find a general formula for the two-loop renormalization counterterms of a scalar quantum field theory with interactions containing up to two...

Extended doubled structures of algebroids for gauged double field theory
We study an analogue of the Drinfel’d double for algebroids associated with the O ( D, D + n ) gauged double field theory (DFT). We show that algebroids...

Effective interactions of the open bosonic string via field theory
We describe a method to extract an effective Lagrangian description for open bosonic strings, at zero transcendentality. The method relies on a...

Hydrodynamic and non-hydrodynamic excitations in kinetic theory — a numerical analysis in scalar field theory
Viscous hydrodynamics serves as a successful mesoscopic description of the Quark-Gluon Plasma produced in relativistic heavy-ion collisions. In order...

The Real Scalar Quantum Field Theory
In this chapter we will examine an example of a relativistic quantum field theory. It contains a single, real scalar field and it will have spacetime...

Topological phase transitions of semimetal states in effective field theory models
Effective relativistic field theory models capable of realizing various gapless topological states are presented in this work. We study the...

A spatiotemporally-nonlocal continuum field theory of polymer networks
A physically-based continuum theory that captures the microstructure-dependent and temporal effects of both permanent and transient polymer networks...

Quantum Field Theory By Academician Prof. Kazuhiko Nishijima - A Classic in Theoretical Physics
This book is a translation of the 8th edition of Prof. Kazuhiko Nishijima’s classical textbook on quantum field theory. It is based on the lectures...

Complete NNLO operator bases in Higgs effective field theory
For the first time, we list the complete and independent set of operators at the next-to-next-to-leading order (NNLO) in the Higgs effective field...

Finiteness of entanglement entropy in collective field theory
We explore the question of finiteness of the entanglement entropy in gravitational theories whose emergent space is the target space of a holographic...

The ZZ annulus one-point function in non-critical string theory: A string field theory analysis
We compute the ZZ annulus one-point function of the cosmological constant operator in non-critical string theory, regulating divergences from the...
