Light neutralino dark matter in U(1)XSSM

open access: yesNuclear Physics B, 2021
The U(1)X extension of the minimal supersymmetric standard model (MSSM) is called as U(1)XSSM with the local gauge group SU(3)C×SU(2)L×U(1)Y×U(1)X. U(1)XSSM has three singlet Higgs superfields beyond MSSM.

A Naturally Renormalized Quantum Field Theory [PDF]

open access: yesInt.J.Theor.Phys.48:2740-2747,2009, 2006
It was shown that quantum metric fluctuations smear out the singularities of Green's functions on the light cone [1], but it does not remove other ultraviolet divergences of quantum field theory. We have proved that the quantum field theory in Krein space, {\it i.e.} indefinite metric quantization, removes all divergences of quantum field theory with ...

Criticality of quantum energy teleportation at phase transition points in quantum field theory [PDF]

open access: yesPhys. Rev. D 107, L071502 (2023), 2023
Quantum field theory can be a new medium for communication through quantum energy teleportation. We performed a demonstration of quantum energy teleportation with a relativistic fermionic field theory of self-coupled fermions, called the massive Thirring model.

Simulating quantum field theory with a quantum computer [PDF]

open access: yesProceedings of The 36th Annual International Symposium on Lattice Field Theory — PoS(LATTICE2018), 2018
Forthcoming exascale digital computers will further advance our knowledge of quantum chromodynamics, but formidable challenges will remain. In particular, Euclidean Monte Carlo methods are not well suited for studying real-time evolution in hadronic ...

Quantum Gravity as Topological Quantum Field Theory [PDF]

open access: yes, 1995
The physics of quantum gravity is discussed within the framework of topological quantum field theory. Some of the principles are illustrated with examples taken from theories in which space-time is three dimensional.Comment: 23 pages, amstex, JMP special

Out-of-horizon correlations following a quench in a relativistic quantum field theory

open access: yesJournal of High Energy Physics, 2020
One of the manifestations of relativistic invariance in non-equilibrium quantum field theory is the “horizon effect” a.k.a. light-cone spreading of correlations: starting from an initially short-range correlated state, measurements of two observers at ...

Toward a Definition of Complexity for Quantum Field Theory States. [PDF]

open access: yesPhysical Review Letters, 2017
We investigate notions of complexity of states in continuous many-body quantum systems. We focus on Gaussian states which include ground states of free quantum field theories and their approximations encountered in the context of the continuous version ...

Quantum spectral dimension in quantum field theory [PDF]

open access: yes, 2016
We reinterpret the spectral dimension of spacetimes as the scaling of an effective self-energy transition amplitude in quantum field theory (QFT), when the system is probed at a given resolution.

Quantum Field Theory Representation in Quantum Computation

open access: yesApplied 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
