The idea is to perturb the free CFT using screening operators of the form (), where () is an affine primary field of conformal dimensions (, ¯) = (,). In spite of its perturbative definition, the technique leads to exact results, thanks to momentum conservation.
In a rational CFT that is defined on all Riemann surfaces, the central charge and conformal dimensions are rational numbers. [6] A CFT is called diagonal if its space of states is a direct sum of representations of the type ¯, where is an indecomposable representation of the left Virasoro algebra, and ¯ is the same representation of the right ...
A conformal field theory (CFT) is a quantum field theory that is invariant under conformal transformations.In two dimensions, there is an infinite-dimensional algebra of local conformal transformations, and conformal field theories can sometimes be exactly solved or classified.
These models describe a thermal particle in a random potential that is logarithmically correlated. In two dimensions, such potential coincides with the Gaussian free field. In that case, certain correlation functions between primary fields in the Liouville theory are mapped to correlation functions of the Gibbs measure of the particle. This has ...
In the AdS/CFT correspondence, one typically considers theories of quantum gravity derived from string theory or its modern extension, M-theory. [10] In everyday life, there are three familiar dimensions of space (up/down, left/right, and forward/backward), and there is one dimension of time.
The three-state Potts CFT, also known as the parafermion CFT, is a conformal field theory in two dimensions. It is a minimal model with central charge = /.It is considered to be the simplest minimal model with a non-diagonal partition function in Virasoro characters, as well as the simplest non-trivial CFT with the W-algebra as a symmetry.
The IEEE symbol for the cubic foot per second is ft 3 /s. [1] The following other abbreviations are also sometimes used: ft 3 /sec; cu ft/s; cfs or CFS; cusec; second-feet; The flow or discharge of rivers, i.e., the volume of water passing a location per unit of time, is commonly expressed in units of cubic feet per second or cubic metres per second.
Another realization of the AdS/CFT correspondence states that M-theory on AdS 4 ×S 7 is equivalent to a quantum field theory called the ABJM theory in three dimensions. In this version of the correspondence, seven of the dimensions of M-theory are curled up, leaving four non-compact dimensions.
