Quantum Canonical Transformations: Physical Equivalence of
... One of the most powerful ways of solving a quantum theory is to make a canonical transformation to a simpler theory in different variables. Following Dirac[1, 2], there is a widespread belief that the unitary transformations are the analog of the classical canonical transformations in quantum theor ...

Symmetries in Conformal Field Theory
... πi (G) is trivial for i < 3 (π2 (G) is always trivial when G is a Lie group), so all maps Σ → G are nullhomotopic. 2. Nevertheless, the extension is generally not unique, which means the action S(φ) given above is actually not well defined. This is certainly not a problem for the classical theory, b ...

Nature of magnetism in double perovskite Ba2NaOsO6
... shells may resist breaking of lattice symmetry in cases where their lighter counterparts would succumb. Ba2NaOsO6 is a rare example of a Os7+ compound (d1: single occupation of the t2g orbits), also being ferromagnetic insulating (Tc ~ 7 K). Nevertheless, this system has the ideal cubic structure, i ...
