5 J ul 2 00 6 Fröhlich Polarons From 3 D to 0 D . Concepts and Recent Developments
نویسنده
چکیده
As is generally known, the polaron concept was introduced by Landau in 1933 [1]. Gradually a distinction was made between polarons in the continuum approximation where long-range electron-lattice interaction prevails (“Fröhlich”polarons) and polarons for which the short-range interaction is essential (Holstein, Holstein-Hubbard models). After a period of initial theoretical [1, 2, 3, 4, 5, 6, 7, 8] and experimental [9] works, a first international meeting was devoted to the subject in St. Andrews (1965, [10]). Ten years later a second international meeting – in which the progress in the field of polarons

Abstract. We review recent results on the charged pion charged hadron correlation in p+ p and d + Au collisions as measured by the PHENIX Collaboration. Properties of di-jet system, such as the jet shape, associated hadron yield per trigger pion, and the underlying event are extracted statistically from the π − h correlation function in ∆φ and ∆η. For jet triggered with high pT pions (pT > 5 Ge...
متن کاملFröhlich polaron and bipolaron: recent developments
It is remarkable how the Fröhlich polaron, one of the simplest examples of a Quantum Field Theoretical problem, as it basically consists of a single fermion interacting with a scalar Bose field of ion displacements, has resisted full analytical or numerical solution at all coupling since ∼ 1950, when its Hamiltonian was first written. The field has been a testing ground for analytical, semi-ana...

Let C ⊂ P be an integral projective curve. One defines the speciality index e(C) of C as the maximal integer t such that h(C, ωC(−t)) > 0, where ωC denotes the dualizing sheaf of C. Extending a classical result of Halphen concerning the speciality of a space curve, in the present paper we prove that if C ⊂ P is an integral degree d curve not contained in any surface of degree < s, in any threef...
متن کاملI-17: Recent Developments in Animal Welfare Sciencee
The methodology for the scientific assessment of animal welfare has developed rapidly in recent years and has become a major scientific discipline. The concepts of welfare, need, stress, health, pain, emotion and feeling are now clarified. In teaching, legislation and practical work referring to animal welfare, a clear definition that can be related to other concepts is needed. The welfare of a...
