A quantum field theory warm inflation model [PDF]
Second international workshop on particle physics and the early universe (COSMO-98), 1999 A quantum field theory warm inflation model is presented that solves the cosmological horizon/flatness problems. An interpretation of the model is given from supersymmetry and superstring theory.

Cold atom simulation of interacting relativistic quantum field theories. [PDF]
Physical Review Letters, 2010 We demonstrate that Dirac fermions self-interacting or coupled to dynamic scalar fields can emerge in the low energy sector of designed bosonic and fermionic cold atom systems. We illustrate this with two examples defined in two spacetime dimensions. The

Some solutions for one of the cosmological constant problems [PDF]
, 2016 We propose several covariant models which may solve one of the problems in the cosmological constant. One of the model can be regarded as an extension of sequestering model. Other models could be regarded as extensions of the covariant formulation of the

Modeling Meridians Within the Quantum Field Theory
Journal of Acupuncture and Meridian Studies, 2019 We present here a model of meridians in the formalism of the gauge theory paradigm of quantum field theory with spontaneous breakdown of symmetry. We discuss the origin and dynamic self-focusing propagation of the electromagnetic field in coherent states and the role it plays in our meridian modeling.

A resource efficient approach for quantum and classical simulations of gauge theories in particle physics [PDF]
Quantum, 2020 Gauge theories establish the standard model of particle physics, and lattice gauge theory (LGT) calculations employing Markov Chain Monte Carlo (MCMC) methods have been pivotal in our understanding of fundamental interactions.

Simulating two-dimensional lattice gauge theories on a qudit quantum computer. [PDF]
Nat Phys, 2023 Particle physics describes the interplay of matter and forces through gauge theories. Yet, the intrinsic quantum nature of gauge theories makes important problems notoriously difficult for classical computational techniques.

Quantum field theory of X-cube fracton topological order and robust degeneracy from geometry [PDF]
, 2017 We propose a quantum field theory description of the X-cube model of fracton topological order. The field theory is not (and cannot be) a topological quantum field theory (TQFT), since unlike the X-cube model, TQFTs are invariant (i.e.

Renormalization of quantum field theories on noncommutative Bbb Rd, 1. Scalars [PDF]
, 1999 A non-commutative Feynman graph is a ribbon graph and can be drawn on a genus g 2-surface with a boundary. We formulate a general convergence theorem for the non-commutative Feynman graphs in topological terms and prove it for some classes of diagrams in
