Properties of Graphene in an External Magnetic
... extremely hard dielectric material and crystallizes in a cubic system. It consists of four sp3 hybridised orbitals, i.e. all outer four valence electrons of the carbon atom permit covalent bondings to four other carbon atoms. In other words, they are all localised between the atoms in covalent bondi ...

Quantum Thermodynamics - Open Research Exeter
... One of the biggest puzzles in quantum theory today is to show how the well-studied properties of a few particles translate into a statistical theory from which new macroscopic quantum thermodynamic laws emerge. This challenge is addressed by the emerging field of quantum thermodynamics which has gro ...

The Classical and Quantum Mechanics of Systems with Constraints
... An other example of this type of thing is the general theory of relativity in vacuum. We may want to write down equations of motion for how the spatial geometry of the universe changes with time. But because the spatial geometry is really the geometry of a 3-dimensional hypersurface in a 4-dimension ...

Electromagnetic vacuum fluctuations, Casimir and Van der Waals
... when the effect of imperfect reflection of mirrors is properly taken into account. We discuss the simple case of bulk metallic mirrors described by a plasma model and show that simple scaling laws are obtained at the limits of long and short distances. The crossover between the short and long-distan ...
