Chiral quantum optics using a topological resonator [PDF]
Physical review B, 2019 Topological photonic structures exhibit chiral edge states that are robust to disorder and sharp bends. When coupled to quantum emitters, these edge states generate directional light emission that enables unprecedented control of interactions between ...

On resonant leptogenesis [PDF]
Journal of Cosmology and Astroparticle Physics, 2007 It has been recently shown that the quantum Boltzmann equations may be relevant for the leptogenesis scenario. In particular, they lead to a time-dependent CP asymmetry which depends upon the previous dynamics of the system. This memory effect in the CP asymmetry is particularly important in resonant leptogenesis where the asymmetry is generated by the

The Case for Procopiu’s Quantum [PDF]
Memoirs of the Scientific Sections of the Romanian Academy, 2022 The general traits of the Planck’s quantization procedure for the case of light are considered. The Procopiu’s quantization is presented as a result of this quantization procedure, only applied not to light, but to matter structures.

Hydrothermally synthesized PZT film grown in highly concentrated KOH solution with large electromechanical coupling coefficient for resonator [PDF]
Royal Society Open Science, 2017 This paper presents a study of lead zirconate titanate (PZT) films hydrothermally grown on a dome-shaped titanium diaphragm. Few articles in the literature address the implementation of hydrothermal PZT films on curved-diaphragm substrates for resonators.
