Filtering of matter wave vibrational states via spatial adiabatic passage
Yu. Loiko, V. Ahufinger, R. Corbalán +2
We discuss the filtering of the vibrational states of a cold atom in an optical trap, by chaining this trap with two empty ones and controlling adiabatically the tunneling. Matter…
Pseudodifferential operators on periodic graphs
Vladimir S. Rabinovich, Steffen Roch
The main aim of the paper is Fredholm properties of a class of bounded linear operators acting on weighted Lebesgue spaces on an infinite metric graph which is periodic with re…
Semistability of restricted tangent bundles and a question of I. Biswas
Priska Jahnke, Ivo Radloff
Let M be a complex projective manifold with the property that for any compact Riemann surface C and holomorphic map f: C -> M the pullback of the tangent bundle of M is semistable.…
Defect Polytopes and Counter-Examples With polymake
Michael Joswig, Andreas Paffenholz
It is demonstrated how the software system polymake can be used for computations in toric geometry. More precisely, counter-examples to conjectures related to A-determinants and de…
SU(2) Dirac-Yang-Mills quantum mechanics of spatially constant quark and gluon fields
H. -P. Pavel
The quantum mechanics of spatially constant SU(2) Yang-Mills- and Dirac-fields minimally coupled to each other is investigated as the strong coupling limit of 2-color-QCD. Using a…
Double-Slit Experiments with Microwave Billiards
S. Bittner, B. Dietz, M. Miski-Oglu +3
Single and double-slit experiments are performed with two microwave billiards with the shapes of a rectangle, respectively, a quarter stadium. The classical dynamics of the former…
