Quantum Field Theory Representation in Quantum Computation
Applied Sciences, 2021 Recently, from the deduction of the result MIP* = RE in quantum computation, it was obtained that Quantum Field Theory (QFT) allows for different forms of computation in quantum computers that Quantum Mechanics (QM) does not allow. Thus, there must exist

A spin-statistics theorem for quantum fields on curved spacetime manifolds in a generally covariant framework [PDF]
, 2001 A model-independent, locally generally covariant formulation of quantum field theory over four-dimensional, globally hyperbolic spacetimes will be given which generalizes similar, previous approaches.

Large Nf quantum field theory [PDF]
International Journal of Modern Physics A, 2018 We review the development of the large [Formula: see text] method, where [Formula: see text] indicates the number of flavours, used to study perturbative and nonperturbative properties of quantum field theories. The relevant historical background is summarized as a prelude to the introduction of the large [Formula: see text] critical point formalism ...

Quantum Spins and Quantum Links: The D-Theory Approach to Field Theory [PDF]
, 1998 A new non-perturbative approach to quantum field theory is proposed. Instead of performing a path integral over configurations of classical fields, D-theory works with discrete quantized variables. Classical spin fields are replaced by quantum spins, and

Advanced Engineering Materials, EarlyView.An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

From quantum field theory to quantum mechanics
European Physical Journal C: Particles and Fields, 2021 The purpose of this article is to construct an explicit relation between the field operators in Quantum Field Theory and the relevant operators in Quantum Mechanics for a system of N identical particles, which are the symmetrised functions of the ...

Advanced Engineering Materials, EarlyView.A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation

Quantum Field Theory in Categorical Quantum Mechanics [PDF]
Electronic Proceedings in Theoretical Computer Science, 2019 We use tools from non-standard analysis to formulate the building blocks of quantum field theory within the framework of categorical quantum mechanics.

SPIN TOPOLOGICAL QUANTUM FIELD THEORIES [PDF]
International Journal of Mathematics, 1998 Starting from the quantum group [Formula: see text], we construct operator invariants of 3-cobordisms with spin structure, satisfying the requirements of a topological quantum field theory and refining the Reshetikhin–Turaev and Turaev–Viro models. We establish the relationship between these two refined theories.
