Proposed Search fora00(980)−f0(980)Mixing in Polarization Phenomena

Proposed search for a(0)(0)(980)-f(0)(980) mixing in polarization phenomena.

The K+ and K0 meson mass difference induces the mixing of the a(0)(0)(980) and f(0)(980) resonances, the amplitude of which, between the K+K- and K0(-)K(0) thresholds, is large in magnitude, of the order of m(K)m(2)(K0)sqrt[-m(2)(K+)] approximately sqrt[alpha] m(2)(K), and possesses the phase sharply varying by about 90 degrees. We suggest performing the polarized target experiments on the reac...

Spin Polarization Phenomena in Dense Nuclear Matter

Spin polarized states in nuclear matter with an effective nucleon-nucleon interaction are studied for a wide range of isospin asymmetries and densities. Based on a Fermi liquid theory, it is shown that there are a few possible scenarios of spin ordered phase transitions: (a) nuclear matter undergoes at some critical density a phase transition to a spin polarized state with the oppositely direct...

Relating Search and Stroop Phenomena

Presented with Stroop color-word stimuli, participants were asked to make one response (“Yes”) to the appearance of the word RED, the color red, or both and another response (“No”) when none of these targets (defined by redness) appeared. The same participants also performed in the standard Stroop task, naming the print color of the same set of color words. Because we were careful to (1) constr...

Surface-Stimulated Phenomena in the Polarization Response of Ferroelectrics

The integration of ferroelectrics in electronic devices requires that they be used in the form of thin films, which implies that for such systems finite-size effects related to the presence of a ferroelectric-electrode interface become important. In this thesis, a number of theoretical studies are presented on the properties of metal-ferroelectric-metal structures, focusing on the impact of the...
