The Canonical Approach to Quantum Gravity
... by matter, the interaction between matter and spacetime now goes both ways. Saying that the spacetime is ‘dynamic’ does not mean that it ‘changes’ with respect to any given external time. Time is clearly within, not external to spacetime. Accordingly, solutions to Einstein’s equations, which are who ...

The Spectrum of the Hydrogen Atom
... background on a few of the main contributors to the theory. We go on to explain what wavefunctions are, and define the Schrödinger equation, which we then simplify for hydrogen into a time-independent form. In order to solve this equation, we review the method of separation of variables, using the ...

Quantum Mechanical Ideal Diesel Engine
... As a device to convert heat energy into mechanical work, a thermodynamic heat engine consists of an ideal gas, as a working substance, that expands and pushes a piston in a cylinder. Quantum heat engines produce work using quantum matter as their working substance [1]. Heat engine streams into study ...

Introduction to Single Molecular Magnet
... Yet, there is another kind of paramagnetic behavior exhibited by some metals which arises on the application of magnetic field that can be realized in a free electron gas mode. The density of states of free electron gas in absence of external magnetic field has equal number of up spins and down spins ...
