Modulated instabilities and the AdS2 point in dense holographic matter
Dr. Jesús Cruz Rojas, ICN-UNAM
We investigate the effect that a Chern-Simons term has on the
phase diagram of quark matter at finite density and temperature.
We carried out the complete fluctuation analysis of the chirally
symmetric black hole phase of the holographic model V-QCD which
models the deconfined phase of QCD. We classify all fluctuations
and therefore all quasi-normal modes.
We also analyse the fluctuations at the AdS2 IR point, which
realizes the quantum critical line of the dual theory at zero
temperature and finite density. We computed the dimensions of
the fluctuations in the corresponding one-dimensional IR CFT,
and showed how the (purely imaginary) QNMs of the black hole
phase map to these AdS2 modes as the temperature approaches zero.
As it turns out, the Chern-Simons term in V-QCD introduces a
strong Ooguri-Park instability at finite temperature and chemical
potential, but only at finite momentum. We finally investigate
the region in which the instabilities appear in the phase diagram.
