Quantum Non-Hermitian Topological Sensors
Florian Koch, Jan Carl Budich
We investigate in the framework of quantum noise theory how the striking boundary-sensitivity recently discovered in the context of non-Hermitian (NH) topological phases may be har…
Twist-Deformed Lorentzian Heisenberg-Algebras
Florian Koch
The Moyal-Weyl quantization procedure is embedded into the twist formalism of vector fields on phase space. Double application of twists provide most general deformations of Minkow…
Vector Field Twisting of Lie-Algebras
Florian Koch
In quantum groups coproducts of Lie-algebras are twisted in terms of generators of the corresponding universal enveloping algebra. If representations are considered, twists also se…
Construction of -Poincaré Algebras and their Invariants on
Florian Koch, Efrossini Tsouchnika
In the present paper we construct deformations of the Poincaré algebra as representations on a noncommutative spacetime with canonical commutation relations. These deformations are…
