Logarithmic Primary Fields in Conformal and Superconformal Field Theory [PDF]

Nucl.Phys.B722:249-265,2005, 2005
In this note, some aspects of the generalization of a primary field to the logarithmic scenario are discussed. This involves understanding how to build Jordan blocks into the geometric definition of a primary field of a conformal field theory. The construction is extended to N=1,2 superconformal theories. For the N=0,2 theories, the two-point functions

Confluent primary fields in the conformal field theory [PDF]

Journal of Physics A: Mathematical and Theoretical, 2010
For any complex simple Lie algebra, we generalize primary fileds in the Wess-Zumino-Novikov-Witten conformal field theory with respect to the case of irregular singularities and we construct integral representations of hypergeometric functions of ...

On conformal field theories with low number of primary fields [PDF]

J.Phys.A42:304009,2009, 2008
Using Verlinde formula and the symmetry of the modular matrix we describe an algorithm to find all conformal field theories with low number of primary fields. We employ the algorithm on up to eight primary fields. Four new conformal field theories are found which do not appear to come from current algebras.

Operator Product Expansion in Logarithmic Conformal Field Theory [PDF]

Nucl.Phys. B634 (2002) 511-545, 2001
In logarithmic conformal field theory, primary fields come together with logarithmic partner fields on which the stress-energy tensor acts non-diagonally. Exploiting this fact and global conformal invariance of two- and three-point functions, operator product expansions of logarithmic operators in arbitrary rank logarithmic conformal field theory are ...

Analysis of Primary Field Shielding Stability for the Weak Coupling Coil Designs [PDF]

Sensors, 2020
As an electromagnetic field conversion tool in the transient electromagnetic method (TEM), the weak coupling coils reduce the mutual inductance of its transmitter and receiver coils by special structural optimization, so the detection signal can be ...

Conformal Properties of Primary Fields in a q-Deformed Theory [PDF]

J.Phys. A25 (1992) L149-L155, 1994
We examine some of the standard features of primary fields in the framework of a $q$-deformed conformal field theory. By introducing a $q$-OPE between the energy momentum tensor and a primary field, we derive the $q$-analog of the conformal Ward identities for correlation functions of primary fields. We also obtain solutions to these identities for the

Free Field Realizations of 2D Current Algebras, Screening Currents and Primary Fields [PDF]

Nuclear Physics B, 1997
In this paper we consider Wakimoto free field realizations of simple affine Lie algebras, a subject already much studied. We present three new sets of results. (i) Based on quantizing differential operator realizations of the corresponding Lie algebras we provide general universal very simple expressions for all currents, more compact than has been ...

Influence of the geomagnetic field and of the uncertainties in the primary spectrum on the development of the muon flux in the atmosphere [PDF]

, 2005
In this paper we study the sensitivity of the flux of atmospheric muons to uncertainties in the primary cosmic ray spectrum and to the treatment of the geomagnetic field in a calculation.

Director field model of the primary visual cortex for contour detection. [PDF]

PLoS ONE, 2014
We aim to build the simplest possible model capable of detecting long, noisy contours in a cluttered visual scene. For this, we model the neural dynamics in the primate primary visual cortex in terms of a continuous director field that describes the ...

Mapping receptive fields in primary visual cortex

The Journal of Physiology, 2004
Nearly 40 years ago, in the pages of this journal, Hubel and Wiesel provided the first description of receptive fields in the primary visual cortex of higher mammals. They defined two classes of cortical cells, ‘simple’ and ‘complex’, based on neural responses to simple visual stimuli.
