Comments on Non–Dark Matter Theories Explaining the Galaxy Rotation Curves and Globular Cluster Velocity Dispersions Int. J. Theor. Phys. (IF 1.4) Pub Date : 2024-03-13
Abstract The Carmelies Theory (CT) was successful in Non–Dark Matter explanation of the rotation curves of galaxies. But is this theory also applicable in extragalactic scales or other fields?. In this article, we used this theory for two specific cases (Galaxy Cluster Mass (GCM) and Globular Cluster Velocity Dispersions) and finally (according to the observational data) they have come to the conclusion

Geometric Phase of a Two-level System Driven by a Classical Field Int. J. Theor. Phys. (IF 1.4) Pub Date : 2024-03-12
Abstract We investigated the mixed state geometric phase of a two-level system which is coupled to a bosonic reservoir in both weak and strong coupling regimes, and driven by a classical field. Besides, we extended the direct-drive model to the indirect-drive model by incorporating an additional qubit. In the direct-drive model, the geometric phase undergoes corresponding alterations through the amplification

A K-Theory Approach to Characterize Admissible Physical Manifolds Int. J. Theor. Phys. (IF 1.4) Pub Date : 2024-03-09
Abstract In this work we will classify physically admissible manifold structures by the use of Waldhausen categories. These categories give rise to algebraic K-Theory. Moreover, we will show that a universal K-spectrum is necessary for a physical manifold being admissible. Application to the generalized structure of D-branes are also provided. This might give novel insights in how the manifold structure

Entanglement and Uncertainty in the Special-Relativistic Regime Int. J. Theor. Phys. (IF 1.4) Pub Date : 2024-03-08 S. Hamid Mehdipour
This paper seeks an interplay between entanglement and uncertainty in the special-relativistic regime. A pure quantum state describing the system of identical target particles in a special relativity scenario is adopted to be correlated if, for a pair of position and momentum observables, the quantum covariance functions do not vanish. We explore how the relativistic uncertainty principle (RUP) is

Quantum Features of the Nonlinear Dissipative Cavity Interacting with a Two-Level Atom under the Influence of Stark Shift Int. J. Theor. Phys. (IF 1.4) Pub Date : 2024-03-02
Abstract Generating the entanglement and controlling the non-classical properties are an important topic in quantum optics. In this paper, we consider a system consisting of two-photon Jaynes-Cummings model with an intensity dependent coupling and Kerr term in the presence of the Stark shift and in dispersive approximation. It is assumed that the cavity field is initially provided in the coherent state

Negative-energy and Tachyonic Solutions in the Weinberg-Tucker-Hammer Equation for Spin 1 Int. J. Theor. Phys. (IF 1.4) Pub Date : 2024-02-27 Valeriy V. Dvoeglazov
We considered Weinberg-like equations in the article (Dvoeglazov Rev. Mex. Fis. 65, 612 2019) in order to construct the Feynman-Dyson propagator for the spin-1 particles. This construction is based on the concept of the Weinberg field as a system of four field functions differing by parity and by dual transformations. We also analyzed the recent controversy in the definitions of the Feynman-Dyson propagator

A Secure Quantum Proxy Group Signature Scheme Based on Three-qubit Entangled States Int. J. Theor. Phys. (IF 1.4) Pub Date : 2024-02-26 Lu Lan, Rongbo Lu, Juxiu Zhong, Yuanquan Shi
In this paper, a secure quantum proxy group signature (QPGS) scheme based on three-qubit entangled states is proposed. The three-qubit entangled state functions as a quantum channel, conserving entanglement resources more effectively than similar papers that have been proposed. The properties of proxy signature and group signature are satisfied at the same time. In this scheme, quantum one-time pad

CMB, Hawking, Planck, and Hubble Scale Relations Consistent with Recent Quantization of General Relativity Theory Int. J. Theor. Phys. (IF 1.4) Pub Date : 2024-02-23
Abstract We are demonstrating new relationships among the Hawking temperature, the Cosmic Microwave Background (CMB) temperature, and the Planck scale. When understood deeply, these are in line with recent advancements in cosmological quantization and its connection to the Planck scale. This is also completely consistent with a recently published method for quantizing Einstein’s general theory of relativity

Gödel’s Undecidability Theorems and the Search for a Theory of Everything Int. J. Theor. Phys. (IF 1.4) Pub Date : 2024-02-19 Claus Kiefer
I investigate the question whether Gödel’s undecidability theorems play a crucial role in the search for a unified theory of physics. I conclude that unless the structure of space-time is fundamentally discrete we can never decide whether a given theory is the final one or not. This is relevant for both canonical quantum gravity and string theory. Slightly elaborated version of a Prize winning essay

Electroweak Phase Transition Near the Event Horizon of a Schwarzschild Black Hole Int. J. Theor. Phys. (IF 1.4) Pub Date : 2024-02-19 Yuanxin Li
In this paper the behavior of the electroweak phase transition (EWPT) near the event horizon is investigated. The critical proper distance is estimated. Since the electroweak gauge symmetry is restored and all elementary particles become massless in the vicinity of the horizon, we define an EWPT surface located a short proper distance outside the black hole. Hawking particles with and without mass

A Study of the Violation of the Bell-CHSH Inequality Through a Pairing Mechanism Int. J. Theor. Phys. (IF 1.4) Pub Date : 2024-02-13 S. P. Sorella
The violation of the Bell-CHSH inequality for bipartite systems is discussed by making use of the pseudospin operators which enable us to group all modes of the Hilbert space of the system in pairs. We point out that a single pair can be already employed to perform a test of the Bell-CHSH inequality in order to check out its violation. The mechanism is illustrated with the help of N00N states as well

Abstract The Half-Transform Ansatz (HTA) is a proposed method to solve hyper-geometric equations in Quantum Phase Space by transforming a differential operator to an algebraic variable and including a specific exponential factor in the wave function, but the mechanism which provides this solution scheme is not known.

Singularity for the Drift-Flux System of Two-Phase Flow with the Generalized Chaplygin Gas Int. J. Theor. Phys. (IF 1.4) Pub Date : 2024-01-23
Abstract This article considers the formation of singularity in the one-dimensional isentropic drift-flux system of two-phase flow with the generalized Chaplygin gas. We give an appropriate initial condition that results in the formation of singularity in finite time. Notably, the formation of singularity is accompanied by the concentration of mass. Furthermore, we verify the theoretical results.

Ozawa’s Intersubjectivity Theorem as Objection to QBism Individual Agent Perspective Int. J. Theor. Phys. (IF 1.4) Pub Date : 2024-01-20 Andrei Khrennikov
QBism’s foundational statement that “the outcome of a measurement of an observable is personal” is in the straight contraversion with Ozawa’s Intersubjectivity Theorem (OIT). The latter (proven within the quantum formalism) states that two observers, agents within the QBism terminology, performing joint measurements of the same observable A on a system S in the state \(\psi \) should get the same outcome

Abstract Classical and quantum theories of the Wien velocity filter are presented. The classical theory is based on the beam optical Hamiltonian and the Lie operator method, which readily leads to the results obtained through the widely used differential equations approach. So far, the quantum mechanics of the Wien filter has not been studied. We explain the quantum mechanics of the Wien filter based

Quantum Scalar Field Theory Based on an Extended Least Action Principle Int. J. Theor. Phys. (IF 1.4) Pub Date : 2024-01-10 Jianhao M. Yang
Recently it is shown that the non-relativistic quantum formulations can be derived from an extended least action principle Yang (2023). In this paper, we apply the principle to massive scalar fields, and derive the Schrödinger equation of the wave functional for the scalar fields. The principle extends the least action principle in classical field theory by factoring in two assumptions. First, the
