This book presents the latest developments in world physics. Chapter One discusses quantum spectral imaging research. Chapter Two analyses resonant interaction of acoustic phonons with localises vibrational modes in superlattices. Chapter Three describes the fabrication and functions of organic superlattices. Chapter Four presents specific features of the thermopower behavior of calcium-containing Y-based high-temperature superconductors. Chapter Five examines peculiarities of two-photon holograms of nonlinear quantum optics and their connections with detection possibilities. Chapter Six studies material science and impact crater formation.
