Quantum knots

We construct an exactly solvable example of Sturmian bound states which exist in the absence of any confining potential. Their origin is topological - these states are found to live on certain "knotted" contours C-(N) of complexified coo...

Planarizable Supersymmetric Quantum Toboggans

In supersymmetric quantum mechanics the emergence of a singularity may lead to the breakdown of isospectrality between partner potentials. One of the regularization recipes is based on a topologically nontrivial, multisheeted complex deformations of ...

Supersymmetric quantum mechanics living on topologically non-trivial Riemann surfaces

Supersymmetric quantum mechanics is constructed in a new non-Hermitian representation. Firstly, the map between the partner operators H-(+/-) is chosen antilineax. Secondly, both these components of a super-Hamiltonian R are defined along certain top...

PT-symmetric square well.

Below a (comparatively large) measure of non-hermiticity Y=Y(0)((crit)) 0 of a PT symmetrically complexified square well, bound states are constructed non-numerically. All their energies prove real and continuous in the (Hermitian) limit Z--...

Spacetime and dark matter from spontaneous breaking of Lorentz symmetry

It is shown that a spontaneously-broken gauge theory of the Lorentz group contains Ashtekar's chiral formulation of general relativity accompanied by dust. From this perspective, gravity is described entirely by a connection omega valued in the Lie a...
