Professor Tomozawa's studies include theoretical and experimental work on the solar neutrino problem (the depletion of solar neutrino flux). His work on the enhancement of neutrino cross-sections by magnetoplasma properties attempts to explain observed anticorrelation of the solar neutrino flux and solar activity in recent experiments. Professor Tomozawa is also exploring the possibility of an efficient neutrino detector and a control of radioactivity.

By choosing the metric in general relativity as the exact solution to the Einstein equation that …ts the time delay data, one can determine the gravitational redshift on the surface of neutron stars. The author presents the physical metric that …ts observed time delay data and using the Kerr metric, the author has shown the e¤ect of a pulsar’s rotation on gravitational redshift in the determination of gravitational wave frequency is within 1 %. Based on this result, the author has identi…ed potential pulsar candidates with gravitational wave spectra that will be critical in the study of gravitational redshift and the relationship between rotation and gravitational waves of a neutron star.

Scattering Photons for Quantum In this talk, we have a closer look at different types of dynamics of photons with potential applications in quantum technology. The polarization states of photons are ideal carriers for quantum information since photons travel fast and are relatively robust against decoherence. At the same time, when traveling in free space, it remains difficult to create interactions and to generate entanglement between them. Nevertheless, photons can exhibit a wide range of dynamics. For example, photons in optical cavities with instantaneous quantum feedback can exhibit non-linear and non-ergodic dynamics with potential applications in quantum metrology. Moreover, we study the scattering of photons through semi-transparent mirrors, like beam splitters and mirrors, with applications in quantum information processing. For example, we show that photons can induce long-range interactions between atoms on either side of a semi-transparent mirror for applications in quantum sensing.

Optical Choas: Dynamical complexity of delay-coupled semiconductor Lasers system Mutually delay-coupled semiconductor lasers system show a plethora of dynamical complexity in the emitted radiation due to phase-amplitude coupling factor alpha, α that make them ideal candidate for fundamental studies of coupled oscillators as well as for practical applications ranging from optical communications to computing. On the one hand these dynamical instabilities are undesired features and disturb the many applications where one needs the constant stable high power but on the other hand, they may allow for new methods for secure communications using chaos synchronization. The variety of optical complexity in these systems which we have investigated theoretically as well as experimentally are well behaving, well understood, well classifiable in terms of complex nonlinear dynamics. So the systematic study and control of these nonlinear dynamics provide fundamental insight into the underlying physics of the system. On the basis of which one can redesign the device in order to stabilize the working point against environmental fluctuations or improve the processing, or simply exploit the dynamical performance of a system to one’s advantages.

Surface-Enhanced Optical Processes and a Strong Quadrupole Light-Molecule, Matter Interaction Surface-Enhanced Optical Processes, SERS, SEHRS, and SEIRA are of great interest for physics, chemistry, and biology since they allow strongly increase the sensitivity of these spectroscopic methods and are caused by a fundamental physical mechanism. It is so-called strong quadrupole light-molecule interaction, arising in surface electromagnetic fields, strongly varying in space near a rough metal surface. Just this interaction is responsible for the enhancement in SERS ~, in SEIRA and in SEHRS and significantly higher. Moreover, this interaction is the base for implementation of Single Molecule Detection by SERS, when the enhancement can achieve the value. This interaction is responsible for the appearance of forbidden lines in all these processes on molecules with sufficiently high symmetry. In SEIRA and SEHRS it is expressed in their belonging to the vibrations with a unit irreducible representation of the molecule symmetry group. In SERS these lines are those, caused by vibrations transforming as the dipole moment component, which is perpendicular to the metal surface. One of the main fundamental properties of this interaction is that it is forbidden in molecules with cubic and icosahedral symmetry groups due to the electrodynamical law. This forbiddance is named as the Electrodynamical forbiddance and was observed in a fullerene. At present the theory of the above-mentioned processes, based on this concept is created and explains the most of the observed phenomena, accompanying SERS, SEHRS, and SEIRA.

New technologies based on new materials New challenges for high power/energy high repetition rate pulse-periodical lasers and very important new areas of application are the matter of this review. The most promising application of laser diode assemblies is the creation of a phase-locked diode array as the compact and effective source of laser radiation for a wide spectrum of applications. Another application of laser diodes is the creation of a system of multiple ignition of rocket propellant in the combustion chamber of a launcher. Analysis of a wide range of materials on the basis of stability parameters has shown that silicon carbide produced either by reaction bonding or sublimation has an advantage over other materials in all well-known criteria. Some new areas of SiC technologies implementation are highlighted

PHYSICOCHEMICAL, SPECTRAL-LUMINESCENT AND LASING PROPERTIES OF Yb-CONTAINING HUNTITE-LIKE GLASS The glasses of the (YbxY1-x)2O3-Al2O3-B2O3 with the composition close to the huntite stoichiometry was synthesized and their multi-aspect investigation was carried out. It was established that the glasses are characterized by (1) low efficiencies of cooperative luminescence of Yb-Yb pairs and photobleaching and photodarkening caused by charge exchange of the activator ions as well as by high threshold of laser-induced destruction of the glass surface; (2) the 2F5/2  2F7/2 luminescence band effective width and its limiting quantum yield consist of about 33 nm and 94%, respectively; (3) heat conductivity increases from 0.6 to 0.9 W/mK with rising of Yb2O3 concentration from 0.5 to 10 mol. % and may grow up to 1.3W/mK at additional doping with Sb; (4) the nonlinear index of refraction close to 2.210–13 esu. These glasses lasing parameters at both free-running mode and Q-switched operation were studied and obtained results were compared with the similar parameters of known glasses activated with Yb3+ ions.
