Cosmological perturbations in the energy-momentum squared gravity theory:constraints from gravitational wave standard sirens and redshift space distortions
《Chinese Physics C》2025年第4期199-208,共10页Qi-Ming Fu Xin Zhang 
Supported by the National SKA Program of China(2022SKA0110200,2022SKA0110203);the National Natural Science Foundation of China(12473001,11975072,12247101);the National 111 Project(B16009)。
We investigate the linear cosmological perturbations in the context of the so-called energy-momentum squared gravity(EMSG)theory.Recent research shows that the EMSG theory can reproduce a viable background cosmologica...

The Strange Relationship between the Momentum of a Photon Emitted from an Electron and the Momentum Acquired by the Electron
《Journal of Applied Mathematics and Physics》2024年第7期2652-2664,共13页Koshun Suto 
In quantum mechanics, the energy of a hydrogen atom is minimized when the principal quantum number n is 1. However, the author has previously pointed out that the hydrogen atom has a state where n=0. An electron in th...

Electron Mass in an Atom Is Less than Rest Mass
《Journal of Applied Mathematics and Physics》2023年第12期3953-3961,共9页Koshun Suto 
Einstein’s energy-momentum relationship is a formula that typifies the special theory of relativity (STR). According to the STR, when the velocity of a moving body increases, so does the mass of the body. The STR ass...

The Physical Constant Called the Rydberg Constant Does Not Exist
《Journal of Applied Mathematics and Physics》2023年第9期2621-2629,共9页Koshun Suto 
In classical quantum theory, the Rydberg constant is a fundamental physical constant that plays an important role. It comes into play as an indispensable physical constant in basic formulas for describing natural phen...

Previously Unknown Formulas for the Relativistic Kinetic Energy of an Electron in a Hydrogen Atom
《Journal of Applied Mathematics and Physics》2023年第4期972-987,共16页Koshun Suto 
Einstein’s energy-momentum relationship, which holds in an isolated system in free space, contains two formulas for relativistic kinetic energy. Einstein’s relationship is not applicable in a hydrogen atom, where po...

Energy-Momentum Density of Non-Diagonal Bianchi Type Space-Time in General Relativity and Teleparallel Gravity
《Journal of Applied Mathematics and Physics》2021年第9期2355-2375,共21页Ragab M. Gad Haifaa A. Alharbi 
We calculated the energy-momentum density of non-diagonal Bianchi type space-time in two different theories of gravity, General relativity (GR) and the theory of Teleparallel gravity (TG). Firstly, by applying Einstei...
