Introduction to loop quantum gravity
... Ordinary non-relativistic Hamiltonian mechanics relies on having a time variable to describe evolution. In general relativity however, there is not an external time variable so ordinary mechanics is not broad enough to describe general relativistic systems. The aim is to find a formulation which is ...

... To complete our proposal, we need to consider suitable initial conditions for our dynamical system. It does not make sense to initialize the system in an equilibrium state, i.e. an eigenstate or thermal state of Hˆ 0 + Hˆ int , if one is interested in dynamical effects. Rather, we assume that the sy ...

If the device under excitation is connected to a closed circuit, a portion of the generated charge carriers can escape the material and be measured as the electron beam induced current (EBIC), provided there is a driving force in the circuit. In LEDs, the built-in field at the p–n ...
