The topological meaning of Levinson’s theorem, half-bound states included
We propose to interpret Levinson’s theorem as an index theorem. This exhibits its topological nature. It furthermore leads to a more coherent explanation of the corrections due to resonances at thresholds.
متن کاملThe Topological Meaning Of
Hurewicz [7] has found connections between some topological notions and combinatorial ones. His study gave topological meaning to the definitions of the cardinals b and d. Rec law [11] gave topological meaning to the definition of the cardinal p. We complete the picture presenting a topological notion which gives topological meaning to the definition of the cardinal t. We compare our notion to ...
متن کاملTopological nature of optical bound states in the continuum.
Optical bound states in the continuum (BICs) have recently been realized in photonic crystal slabs, where the disappearance of out-of-plane radiation turns leaky resonances into guided modes with infinite lifetimes. We show that such BICs are vortex centers in the polarization directions of far-field radiation. They carry conserved and quantized topological charges, defined by the winding numbe...
متن کاملThe Generalized Gell-Mann–Low Theorem for Relativistic Bound States
The recently established generalized Gell-Mann–Low theorem is applied in lowest perturbative order to bound–state calculations in a simple scalar field theory with cubic couplings. The approach via the generalized Gell-Mann–Low Theorem retains, while being fully relativistic, many of the desirable features of the quantum mechanical approaches to bound states. In particular, no abnormal or unphy...
متن کاملObserving Majorana bound states of Josephson vortices in topological superconductors.
In recent years there has been an intensive search for Majorana fermion states in condensed matter systems. Predicted to be localized on cores of vortices in certain nonconventional superconductors, their presence is known to render the exchange statistics of bulk vortices non-abelian. Here we study the equations governing the dynamics of phase solitons (fluxons) in a Josephson junction in a to...
