Holographic quantum states [PDF]
, 2010 We show how continuous matrix product states of quantum field theories can be described in terms of the dissipative non-equilibrium dynamics of a lower-dimensional auxiliary boundary field theory.

Running of effective dimension and cosmological entropy in early universe
European Physical Journal C: Particles and Fields, 2020 In this paper, we suggest that the early universe starts from a high-energetic state with a two dimensional description and the state recovers to be four dimensional when the universe evolves into the radiation dominated phase.

On Quantum Field Theory. I: Quantum Field Theory as Quantum Mechanics [PDF]
Progress of Theoretical Physics, 1974 A new approach to finding a steady foundation of quantum field theory is investigated with the help of the so-called non-standard mathematics. We construct a model of the quan"tum field theory as quantum mechanical system with very much degrees of freedom.

BQP-completeness of scattering in scalar quantum field theory [PDF]
Quantum, 2017 Recent work has shown that quantum computers can compute scattering probabilities in massive quantum field theories, with a run time that is polynomial in the number of particles, their energy, and the desired precision.

Field Redefinition Invariance in Quantum Field Theory [PDF]
, 2000 The issue of field redefinition invariance of path integrals in quantum field theory is reexamined. A ``paradox'' is presented involving the reduction to an effective quantum-mechanical theory of a $(d+1)$-dimensional free scalar field in a Minkowskian ...

Electric dipole moments of neutron and heavy quarks c, t in CP violating U(1)XSSM
Nuclear Physics B, 2022 We study and analyze the electric dipole moments (EDMs) of neutron and heavy quarks c, t in a CP-violating (CPV) supersymmetric U(1) extension of the standard model called U(1)XSSM, whose local gauge group is U(1)X×SU(3)C×SU(2)L×U(1)Y.

On Bethe vectors in gl3 $$ \mathfrak{g}{\mathfrak{l}}_3 $$-invariant integrable models
Journal of High Energy Physics, 2018 We consider quantum integrable models solvable by the nested algebraic Bethe ansatz and possessing gl3 $$ \mathfrak{g}{\mathfrak{l}}_3 $$-invariant R-matrix.

Quantum theory of noncommutative fields [PDF]
Journal of High Energy Physics, 2003 Generalizing the noncommutative harmonic oscillator construction, we propose a new extension of quantum field theory based on the concept of "noncommutative fields". Our description permits to break the usual particle-antiparticle degeneracy at the dispersion relation level and introduces naturally an ultraviolet and an infrared cutoff ...
