What black holes teach about strongly coupled particles
... variant with respect to supersymmetry (which pairs integerspin particles with half-integer-spin ones). The gauge symmetry of the theory is SU(Nc); as we will soon show, if the duality is to be useful, Nc must be large. A combination of Nc and the dimensionless Yang–Mills coupling gYM sets the socall ...

Localization, interaction and the modern interpretation(s) of quantum mechanics
... will also be instructive to treat the trajectories as in standard non-linear dynamics and measure their Lyapunov exponents if these exist. Many-body interactions: We intent to compute the two-interacting particle problem of excitons in an Aharonov-Bohm quantum ring where the magnetic field induced q ...

“What is quantum theory about?” Jos Uffink March 26, 2010, Utrecht
... The task for those who claim it is rather a representation of personal beliefs is to show how this (in their eyes mistaken) view can be so fruitful. =⇒ The quantum de Finetti Theorem. ...

... In this section we apply our results to the concrete special measurement model of quantum stochastic mechanics -- the only dynamic model which is considered in the theory of continuous in time indirect measurements. This measurement model satisfies the principles of nondemolition observation [9-15]. ...

Topological insulators and superconductors
... In the classical world we have solid, liquid and gas. The same H2O molecules can condense into ice, water or vapor. In the quantum world we have metals, insulators, superconductors, magnets etc. Most of these states are differentiated by the broken symmetry. ...
