- Igor Ivanov (Sun Yat-sen University)
The Real 2HDM with a softly-broken Z_2 symmetry is expected to receive divergent CP-violating radiative corrections from the CP phase in the CKM matrix, as emphasized by Fontes et al. four years ago. I will describe a new approach combining the properties of renormalization group equations, the momentum structure of divergences in Feynman diagrams, and approximate symmetries between...
By employing the Bloch-sphere formalism, I will present a novel class of unstable qubits, which are called Critical Unstable Qubits (CUQs). The characteristic property of CUQs is that the energy-level and decay-width Pauli vectors, E and Γ, are orthogonal to one another, and the key parameter r = |Γ|/(2|E|) is less than 1. A remarkable feature of CUQs is that they exhibit atypical behaviours...
