Quasicoherent states of noncommutative D2-branes, Aharonov-Bohm effect and quantum Mobius strip
David Viennot
We find an analytical formula for the quasicoherent states of 3D fuzzy spaces defined by algebras generated by bosonic creation and annihilation operators. This one is expressed in…

Ergodic and synthetic Koopman analyses of cat maps onto classical 2-tori
David Viennot
We study classical continuous automorphisms of the torus (cat maps) from the viewpoint of the Koopman theory. We find analytical formulae for Koopman modes defined coherently on th…
