Subtleties of non-Abelian D-brane actions and their effect on holographic heavy-light meson spectra
Carlos Hoyos, Niko Jokela, Andrea Olzi
We revisit the holographic description of heavy light mesons in the D3-D7 system at zero temperature, analyzing the dynamics of the coupled probe D7 branes through the non-Abelian…

Thermal response of the Nieh-Yan term
Carlos Hoyos, Niko Jokela, José Manuel Penin
We reinterpret the Nieh-Yan (NY) anomaly using holography, finding that the U(1) axial symmetry remains unbroken and the axial current coupling to an external gauge field is conser…
