Quantum Coherence of Critical Unstable Two-Level Systems
Dimitrios Karamitros, Thomas McKelvey, Apostolos Pilaftsis
We study in detail the dynamics of unstable two-level quantum systems by adopting the Bloch-sphere formalism of qubits. By employing the Bloch-vector representation for such unstab…
Towards a Localised S-Matrix Theory
Dimitrios Karamitros, Apostolos Pilaftsis
We formulate an S-matrix theory in which localisation effects of the particle interactions involved in a scattering process are consistently taken into account. In the limit of an…
Tri-Resonant Leptogenesis in a Seesaw Extension of the Standard Model
P. Candia da Silva, D. Karamitros, T. McKelvey +1
We study a class of leptogenesis models where the light neutrinos acquire their observed small masses by a symmetry-motivated construction. This class of models may naturally inclu…
Ultraviolet freeze-in baryogenesis
Andreas Goudelis, Dimitrios Karamitros, Pantelis Papachristou +1
We study a mechanism through which the cosmic dark matter density can be explained simultaneously with the observed baryon asymmetry of the Universe. At the core of our proposal li…
MiMeS, the Misalignment Mechanism Solver
Dimitrios Karamitros
We briefly discuss MiMeS, a C++ library that can solve the axion and axion-like equation of motion in various axion models and cosmological histories.
