The theory is based on a disorder field theory dual to the order field theory of L. Max Born Prize Majorana Prize For superconductors he predicted in a tricritical point in the phase diagram between type-I and type-II ontegrals where the order of the transition changes from second to first.

From Wikipedia, the free encyclopedia. A consistent implementation of this property leads to an extension of the theory of generalized functions by defining uniquely products of distributions.

### Homepage of Hagen Kleinert

This curvature reproduces all the effects of general relativitybut leads to different physics than string theory at hageh scale of the Planck length. In this theory, the statistical properties of fluctuating vortex or defect lines ;ath described as elementary excitations with the help of fields, whose Feynman diagrams are the pictures of the lines.

Landau for phase transitions which Kleinert developed in the books on Gauge Fields in Condensed Matter. Hagen Kleinert No preview available – In he introduced [20] stiffness into the theory of stringswhich had formerly been characterized by tension alone.

His contribution [1] to the memorial volume celebrating the th birthday of Lev Davidovich Landau earned him the Majorana Prize with Medal. Tunneling processes are treated in detail, with applications to intdgrals lifetimes of supercurrents, the stability of metastable thermodynamic phases, and the large-order behavior of perturbation expansions.

Kleinert earned his doctorate in at the University of Colorado, Boulder. Hgaen 60th birthday was honored by a Festschrift and a Festcolloquium with 65 contributions by international colleagues for instance Y.

## Hagen Kleinert

For his contributions to particle and solid state physics he was awarded the Max Born Prize with Medal. The experimental verification is still missing. Chervyakov, Kleinert developed an extension of the theory of distributions from linear spaces to semigroups by defining their products uniquely in the mathematical theory, only linear combinations are defined. By using this site, you agree to the Terms of Use and Privacy Policy. This so-called variational perturbation theory yields at present the most accurate theory of critical exponents [7] observable close to second-order phase transitionsas confirmed for superfluid helium in satellite experiments.

At the summer school in Erice he proposed the existence of broken supersymmetry in atomic nuclei, [15] which has since been observed experimentally. The second is a new nonholonomic mapping principle carrying physical laws in flat spacetime to spacetimes with curvature and torsion, which leads to time-sliced path integrals that are manifestly invariant under coordinate transformations.

Maki he proposed and clarified in a possible icosahedral phase of quasicrystals. Annemarie Kleinert since with whom he has a son Michael Kleinert. Please help improve it by revising it to be neutral and encyclopedic.

Polyakov simultaneously proposed a similar extension, and so the model is now known as the Polyakov-Kleinert string. He is married to Dr. Special attention is devoted to path integrals with topological restrictions needed to understand the statistical properties of elementary particles and the entanglement phenomena in polymer physics and biophysics.

Devreeseand K. This page was last edited on 28 Septemberat Views Read Edit View history. Hagen Kleinert Limited preview – The convergence is uniform from weak to strong couplings, opening a way to precise evaluations of analytically unsolvable path hagej in the strong-coupling regime where they describe critical phenomena.

Inhe considered the existence of a novel Riemann particle.
