The Wigner rotation is important in many branches of physics, chemistry, and engineering sciences. It is a group theoretical effect resulting from two Lorentz boosts. The net effect is one boost followed or preceded by a rotation. While the term "Wigner rotation" is derived from Wigner's little group whose transformations leave the four-momentum of a given particle invariant, it is shown that the Wigner rotation is different from the rotations in the little group. This difference is clearly spelled out, and it is shown to be possible to construct the corresponding Wigner rotation from the little-group rotation. It is shown also that the ABCD matrix for light beams in a laser cavity shares the same mathematics as the little-group rotation, from which the Wigner rotation can be constructed.

Time-space fractional governing equations of one-dimensional unsteady open channel flow process: Numerical solution and exploration Ercan, Ali; Kavvas, M. Levent (2017-07-01) Although fractional integration and differentiation have found many applications in various fields of science, such as physics, finance, bioengineering, continuum mechanics, and hydrology, their engineering applications, especially in the field of fluid flow processes, are rather limited. In this study, a finite difference numerical approach is proposed to solve the time-space fractional governing equations of 1-dimensional unsteady/non-uniform open channel flow process. By numerical simulations, results of...
Computational networks and systems - homogenization of variational problems on micro-architectured networks and devices Kropat, Erik; Meyer-Nieberg, Silja; Weber, Gerhard Wilhelm (2019-05-04) Networked materials and micro-architectured systems gain increasingly importance in multi-scale physics and engineering sciences. Typically, computational intractable microscopic models have to be applied to capture the physical processes and numerous transmission conditions at singularities, interfaces and borders. The topology of the periodic microstructure governs the effective behaviour of such networked systems. A mathematical concept for the analysis of microscopic models on extremely large periodic n...
Stochastic delay differential equations Aladağlı, E. Ezgi; Yolcu Okur, Yeliz; Vardar Acar, Ceren; Department of Financial Mathematics (2017) In many areas of science like physics, ecology, biology, economics, engineering, financial mathematics etc. phenomenas do not show their effect immediately at the moment of their occurrence. Generally, they influence the future states. In order to understand the structure and quantitative behavior of such systems, stochastic delay differential equations (SDDEs) are constructed while inserting the information that are obtained from the past phenomena into the stochastic differential equations (SDEs). SDDEs b...
Assessment of antimicrobial and coagulant activities of CBRN decontamination materials Tosun, Barış Çağrı; Öktem, Hüseyin Avni; Department of Biology (2022-2) CBRN Defense is an emerging interdisciplinary branch of science that combines physics, chemistry and biology together in a unique and complementary way. Concept of decontamination, which is a necessity to neutralize or reduce the spread of contaminants, is one of the key topics in this area of study, and many of the commercially available products are in liquid form and mainly intended to be used for decontamination of environment and equipments. Material used in this study is in powder form that is not dis...
Numerical studies of Korteweg-de Vries equation with random input data Üreten, Mehmet Alp; Yücel, Hamdullah; Uğur, Ömür; Department of Scientific Computing (2018) Differential equations are the primary tool to mathematically model physical phenomena in industry and natural science and to gain knowledge about its features. Deterministic differential equations does not sufficiently model physically observed phenomena since there exist naturally inevitable uncertainties in nature. Employing random variables or processes as inputs or coefficients of the differential equations yields a stochastic differential equation which can clarify unnoticed features of physical event...
