Stochastic Gravitational Waves from Modulated Reheating
Michele Benaco, Dimitrios Karamitros, Sami Nurmi +1
We investigate scalar-induced stochastic gravitational waves from adiabatic curvature perturbations sourced by a spectator field via the modulated reheating mechanism. We consider…
Critical Unstable Qubits in Particle Physics
Dimitrios Karamitros, Thomas McKelvey, Snehit Panghal +1
We study in detail the dynamics of unstable two-level quantum systems by adopting the Bloch-vector representation. We identify a novel class of critical scenarios in which the so-c…
Critical Unstable Qubits: an Application to -Meson System
Dimitrios Karamitros, Thomas McKelvey, Apostolos Pilaftsis
We extend our previous work on a novel class of unstable qubits which we have identified recently and called them Critical Unstable Qubits (CUQs). The characteristic property of CU…
Leptogenesis and the relativistic degrees of freedom of the plasma
Dimitrios Karamitros, Thomas McKelvey, Apostolos Pilaftsis
We investigate the impact of the temperature dependence of the relativistic degrees of freedom (dofs) of the plasma on lepton and baryon asymmetry. Motivated by the significant eff…
