How Different Is More? : Precision correlators at large R-charge |
|
Résumé |
Building up macroscopic physics from microscopic constituents is an idea as old as
theoretical physics itself, and has been a perennial theme in quantum theory
beginning with Bohr's correspondence principle and onward through the modern
renormalization group. Recently there has been a semi-organized effort at
applying this principle to strongly coupled conformal field theory, developing
asymptotic series in inverse powers of a large quantum number as a systematic
approximation scheme whose leading-order term is the familiar macroscopic limit.
I will discuss this idea in the case of N=2 superconformal gauge theory in four
dimensions, where it is possible to compute the large-quantum-number asymptotic
series to all orders and even a hyperasymptotic series for the exponentially small
corrections to it that are associated with the leading qualitative breakdown of
the naive macroscopic picture. The results quite easily yield approximations
accurate to 4-6 significant digits for quantum numbers of order 1, to 15
significant digits or better for quantum numbers of order 100. I will discuss the
implications for one's general picture of the large-scale structure of theory
space. |
