Moreover, if the driving becomes non-periodic and time-invariant, the studied system acquires continuous time translation symmetry. Although the potential heating problem of continuous driving can be worse compared to that of a periodic force, continuous time translation symmetry can also be spontaneous...
Space-Time Field Reactor Physics Fast Faraday Force Flux Field Reactor (FFFFFR?) Mostly this project is just about exploring the rotation space of log-quaternions. This is a development sandbox for a physics engine. It started with an investigation into keeping rotations as rotation vectors, event...
Gravity is a force. It pulls objects with mass toward each other. The moon has less gravity than Earth. This means it does not pull on things as strongly. For example, let's say that an astronaut drops something ...

General relativity is a physical theory about space and time and it has a beautiful mathematical description. According to general relativity, the spacetime is a 4-dimensional object that has to obey an equation, called the Einstein equation, which explains how the matter curves the spacetime. ...
Consequently, there is no requirement for any additional force to maintain the constancy of the graphene charge density. It’s worth emphasizing that electron tunneling is exclusively achievable through the SiO\(_{2}\) layer; tunneling through the Al\(_{2}\)O\(_{3}\) layer is rendered ...
There are two separate possible sources for the force (ordrift) of the back-reaction of the quantum system on phase space—it can be sourced by either the\({D}_{1,\,i}^{0\alpha }\)components or the Lindbladian components\({D}_{1,\,i}^{\alpha \beta }\). We shall deal with...
