Ricci flows and infinite dimensional algebras
I. Bakas
The renormalization group equations of two-dimensional sigma models describe geometric deformations of their target space when the world-sheet length changes scale from the ultra-v…
Generalised coherent states of spinning relativistic particles
Charis Anastopoulos
We construct coherent states of the massless and massive representations of the Poincaré group. They are parameterised by points on the classical state space of spinning particles.…
Arbitrary rotation and entanglement of flux SQUID qubits
Z. Kis, E. Paspalakis
We propose a new approach for the arbitrary rotation of a three-level SQUID qubit and describe a new strategy for the creation of coherence transfer and entangled states between tw…
Supersymmetric quantum mechanics from wrapped branes
Rafael Hernandez, Konstadinos Sfetsos
We explicitly construct a solution of eight-dimensional gauged supergravity representing D6-branes wrapped on six-cycles inside Calabi-Yau fourfolds. The solution preserves two sup…
Enhanced Nonlinear Generation in a Three-Level Medium with Spatially Dependent Coherence
E. Paspalakis, Z. Kis
We consider a method for efficient parametric generation of a laser pulse. A single laser field is injected to a three-level medium which has two lower states and one excited state…
Renormalization group flows and continual Lie algebras
Ioannis Bakas
We study the renormalization group flows of two-dimensional metrics in sigma models and demonstrate that they provide a continual analogue of the Toda field equations based on the…
