| Abstract: |
We study holographic probes dual to heavy quark impurities interpo- lating between fundamental and symmetric/antisymmetric tensor representations in strongly coupled N = 4 supersymmetric gauge theory. These correspond to non- conformal D3- and D5-brane probe embeddings in AdS_5 × S^5 exhibiting flows on their world-volumes. By examining the asymptotic regimes of the embeddings and the one-point function of static fields sourced by the boundary impurity, we con- clude that the D5-brane embedding describes the screening of fundamental quarks in the UV into an antisymmetric source in the IR, whilst the non-conformal, D3- brane solution interpolates between the symmetric representation in the UV and fundamental sources in the IR. The D5-brane embeddings exhibit nontrivial ther- modynamics with multiple branches of solutions, whilst the thermal analogue of the interpolating D3-brane solution does not appear to exist. |
