Confinement from Instantons or Merons *
In contrast to ensembles of singular gauge instantons, which are well known to fail to produce confinement, it is shown that effective theories based on ensembles of merons or regular gauge instantons do produce confinement. Furthermore, when the scale is set by the string tension, the action density, topological susceptibility, and glueball masses are similar to those arising in lattice QCD.
متن کاملCan Merons Describe Confinement?
Merons, conjectured as a semiclassical mechanism for color confinement in QCD, are topological charge-1/2, singular solutions to the classical Yang-Mills equations of motion. I will discuss how lattice techniques can extend the study of merons to nonsingular stationary solutions without destroying properties believed to be essential for confinement, and how zero modes can be used to identify th...
متن کاملSphalerons, Merons, and Unstable Branes in AdS
We construct unstable classical solutions of Yang-Mills theories and their dual unstable states of type IIB on AdS5. An example is the unstable D0-brane of type IIB located at the center of AdS. This has a field theory dual which is a sphaleron in gauge theories on S3 × R. We argue that the two are dual because both are sphalerons associated to the topology of the instanton/D-instanton. This ag...
متن کاملFractionalization into merons in quantum dots.
We study by exact diagonalization, in the lowest Landau level approximation, the Coulomb interaction problem of N=4 and N=6 quantum dots in the limit of zero Zeeman coupling. We find that meron excitations constitute the lowest lying states of the quantum dots. This is based on a mapping between the excitations of the dot and states of the Haldane-Shastry spin chain.
متن کاملHadronic String from Confinement
The existence of hadronic string is derived as a consequence of confinement in QCD. A state of “stretched glue”, created by a Polyakov loop operator, is shown to have translational zero-modes which are stringy degrees of freedom. These modes are described by an effective string theory, valid for worldsheets which are locally flat on length scales of order Λ QCD, the dominant behavior being give...
