2‐Adic Quantum Mechanics, Continuous‐Time Quantum Walks, and the Space Discreteness
Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract The authors show that a large class of 2‐adic Schrödinger equations is the scaling limit of certain continuous‐time quantum Markov chains (CTQMCs). Practically, a discretization of such an equation gives a CTQMC. As a practical result, new types of continuous‐time quantum walks (CTQWs) on graphs using two symmetric matrices are constructed ...

Spinorial space-time and the origin of Quantum Mechanics. The dynamical role of the physical vacuum
EPJ Web of Conferences, 2016 Is Quantum Mechanics really and ultimate principle of Physics described by a set of intrinsic exact laws? Are standard particles the ultimate constituents of matter?

Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

The Variable Rotation Measure Distribution in 3C 273 on Parsec Scales
Galaxies, 2018 We briefly review how opacity affects the observed polarization in synchrotron emitting jets. We show some new multi-frequency observations of 3C 273 made with the VLBA in 1999–2000, which add significantly to the available rotation measure (RM ...

On Geodesic Motion in Horava-Lifshitz Gravity
, 2010 We propose an action for a free particle in Horava-Lifshitz gravity based on Foliation Preserving Diffeomorphisms. The action reduces to the usual relativistic action in the low energy limit and allows for subluminal and superluminal motions with upper ...

Energy Science &Engineering, Volume 13, Issue 6, Page 2757-2771, June 2025.ABSTRACT Conducting an inquiry into the structural, mechanical, electrical, and optical aspects of Ge‐based InGeX3 (Cl, Br, and I) halide perovskites using the density functional theory approach is the main objective of this study. The investigation reveals that substituting the bigger halogen atoms (Br and I) with the smaller halide (Cl) enhances the ...

Superluminal Motion in Weak Quasar Cores [PDF]
Symposium - International Astronomical Union, 1984 The importance of studying the statistics of the occurrence of superluminal motion in an unbiased sample of radio sources is stressed, and methods for selecting such samples are reviewed. The weak radio cores of quasars exhibiting extended, double-lobed emission can be used for this purpose.

Superluminal propagation of light in gravitational field and non-causal signals
, 1998 It has been found in several papers that, because of quantum corrections, light front can propagate with superluminal velocity in gravitational fields and even in flat space-time across two conducting plates.

Advances in Mathematical Physics, Volume 2025, Issue 1, 2025.Lorentz transformations are central to relativistic mechanics, explaining phenomena such as the mass–energy relationship, spatial contraction, momentum transformation, velocity addition, and the geometric structure of Minkowski space‐time. While traditionally derived for motion along a single spatial axis, these transformations can be generalized to ...
