The average is taken over the many-body ground state and A(t) is given in the Heisenberg representation. The + sign applies when the operators A and B satisfy fermion anticommutation relations and the − sign applies if A and B are boson operators. For some applications it is useful to consider Green's functions without time ordering. physics, branch of science science [Lat. scientia=knowledge].For many the term science refers to the organized body of knowledge concerning the physical world, both animate and inanimate, but a proper definition would also have to include the attitudes and methods through which this body of Click the link for more information. traditionally defined as the study of matter matter. The spectral properties and thermal behavior of Saturn's rings are determined from a dataset of ten radial mosaics acquired by Cassini-VIMS (Visual and Infrared Mapping Spectrometer) between October 29th and January 27th with phase angle ranging between degrees and degrees and elevation angles between degrees and degrees. The book covers a variety of topics, ranging from theoretical developments in game theory and algorithmic methods to applications, examples, and analysis in fields as varied as environmental management, finance and economics, engineering, guidance and control, and social interaction.
The developed method is a combination of split-operator method and pseudospectral method and includes non-stationary problem and especially derived boundary conditions (both at x 0 and x Lx, and.

Rapid development over the last two decades has produced more than quantum simulators in operation. The contributions are highly interdisciplinary, emphasizing common concerns among theorists who apply many-particle methods in such diverse areas as solid-state, low-temperature, statistical, nuclear, particle, and biological physics, as well as in quantum field theory, quantum information and the theory of complex systems.

Infrared spectra of atmospheric gases were recorded by Ångström already at the end of the 19th century [15, ], some 40 years before the development of the quantum mechanical formalism necessary to understand the observed spectra.
The key to achieving a narrow speed distribution of the F-atom beam source (v/Δv ~ 10) is shortening the main discharge pulse width. And the double-stage discharge provides a high F-atom density in the beam [64, 65].
A further narrowing of the speed distribution of the F atom was obtained by additional cryo-cooling of the beam source. Primary biological aerosol particles (PBAP) encompass many particle types that are derived from several biological kingdoms.
These aerosol particles can be composed of both whole living units such as pollen, bacteria, and fungi, as well as from mechanically formed particles, such as plant debris. They constitute a significant proportion of the overall atmospheric particle load and have been.

Model samples of LiF crystals: (а) continuous distribution of paramagnetic complexes, (b) distribution with the "hole" inside the sample. To understand the radiation inside the cavity, one needs simply to analyze the spectral distribution of the radiation coming out of the hole.
