Nuclear TheoryThis chapter provides a review of microscopic theories of pairing in nuclear systems and neutron stars. Special attention is given to the mean-field BCS theory and its extensions to include effects of polarization of the medium and retardation of the interactions. Superfluidity in ...
Inequivalent representations of commutator or anticommutator rings of field operators and their applications Hamiltonian of a system in quantum field theory can give rise to infinitely many partition functions which correspond to infinitely many inequivalent repre...

Characterization of UV- B radiation induced alterations in energy transfer in photosystem II of the cyanobacterium, Spirulina platensis using in vivo and...
It summarizes the most significant contributions to the microscopic theory of superconductivity by Russian physicists during the next few years that gave the theory its modern form.关键词: Philosophy of science Evolutionary theory Complex adaptive systems Behavioralism New institutionalisms DOI: 10.1142/S...
Heat engines convert thermal energy into mechanical work both in the classical and quantum regimes1. However, quantum theory offers genuine non-classical forms of energy, different from heat, which so far have not been exploited in cyclic engines. Here we experimentally realize a quantum many-body...
Besides, the multi-antenna transmission is difficult to combine with the FBMC system, limiting its applications. While, f-OFDM can be easily combined with multi-antenna transmission without the need for any special processing. In UFMC, the filter’s length is usually restricted by cyclic prefix ...
In general, there are three main prediction methods: statistical models, physical models and machine learning models. The physical model relies on dynamics between the studied phenomena and physics laws [10]. The statistical model mainly depends on historical data, statistics and probability theory to...
-utilize the theory of less compression on top of column and more on bottom -make a strictly architectural expression -offset the slimness of bottom and equal the loads -prevent cracking or failure from heavy concentrated loads being transferred to point loads at the column ...
Euclidean Quantum Field Theory. 3 The index “V ” here refers to “Villain”. The XY model with “standard (cosine) action” has the partition function Z XY = π −π x dΘ x exp β XY cos(Θ x −Θ y ) . (9) The standard action is the mostly discussed action for an XY...
