We give the most general Hamiltonian and dissipative channels for an open quantum system that contains two modes, and interacts with the environment via two dissipative channels, in such a manner that the system is ...

A new approach generalizing the geometrical concepts describing gravity is proposed. As an application, It is shown that the f(R) and other modified theories of gravity are special cases

A model of the Lyra universe is presented. Using the tunneling effect pproach, the Hawking radiation temperature near the black hole horizon is calculated

A QCD model based on the Seiberg-Witten non commutative geometry is discussed and some applications to hadronic processes at the LHC and Tevatron are also presented. New bounds on the non commutativity parameter are found

The entanglement entropy of pure states is discussed within a cosmological non commutative 2D de Sitter space-time. The obtained results are shown to depend strongly on the sign and values of the non commutativity ...

A model based on the ungravity proposal is presented. Some applications explaining dark energy and dark matter are discussed

In this work we present an important contribution to the non-commutative approach to the hydrogen atom to deal with lamb shift corrections. This can be done by studying the Klein-Gordon equation in a non-commutative ...

The dynamics of a two interacting qubits, each coupled to its own ferromagnetic spin environment and subjected to an external magnetic field is studied. The behavior of the entanglement is investigated. It is shown that ...

L'équation de Drinfel'd-Sokolov généralisée est étudiée en utilisant la méthode de la variable fonctionnelle. Cette méthode peut construire les solutions solitaires, des solutions de patterns, des compactons. Nous avons ...

The consideration of the three-body monopole effects can solve the spectroscopic problems resulting from the failure of the two body realistic interactions to reproduce some nuclear properties. In the framework of studying ...
