“…As studied in [52,53,51], it implies some excited states in the dual field theory with a constant homogeneous field strength background may be described in the D0-D4 model, or equivalently, the dual field theory behaves like θdependent Yang-Mils (YM) theory. By following [52,53,54], we can evaluate the expectation value of TrF ∧ F as TrF ∧ F = 8π 2 N cκ . So the deformed relations to the QCD variables in the presence of D0-branes are given as,…”

“…using the WSS model in the D0-D4 brane background. Notice that we have studied the N f = 2 two-flavor case with this model in [54,62], so it would be natural to extend the present analysis to the case of three flavors N f = 3. The main content of this manuscript consists of two parts.…”

“…In the first part, through the analysis in [63], we search for a instanton solution for the flavored gauge field in the situation with N f = 3 by including the D0-branes. Then following [54] and employing the soliton picture, we derive the effective Hamiltonian for the collective modes of baryon. After quantization, the baryon spectrum can be obtained and all the calculations are done in the strong coupling limit.…”

With the construction of the Witten-SakaiSugimoto model in the D0-D4 background, we systematically investigate the holographic baryon spectrum in the case of three flavors. The background geometry in this model is holographically dual to U (N c ) Yang-Mills theory in large N c limit involving an excited state with a nonzero θ angle or glue condensate TrF ∧ F = 8π 2 N cκ , which is proportional to the charge density of the smeared D0-branes through a parameter b orκ. The classical solution of baryon in this model can be modified by embedding the BelavinPolyakov-Schwarz-Tyupkin instanton and we carry out the quantization of the collective modes with this solution. Then we extend the analysis to include the heavy flavor and find that the heavy meson is always bound in the form of the zero mode of the flavor instanton in strong coupling limit. The mass spectrum of heavy-light baryons in the situation with single-and double-heavy baryon is derived by solving the eigen equation of the quantized collective Hamiltonian. Afterwards we obtain that the constraint of stable baryon states has to be 1 < b < 3 and the difference in the baryon spectrum becomes smaller as the D0 charge increases. It indicates that quarks or mesons can not form stable baryons if the θ angle or glue condensate is sufficiently large. Our work is an extension of the previous study of this model and also agrees with those conclusions.

“…There can also be more generic non-supersymmetric Dp-D(p + 4) solutions in ten-dimensional supergravities [20][21][22]. These brane solutions are useful in gravity-gauge duality applications [23][24][25][26][27][28] and in constructing lower dimensional black holes [21]. The dynamical stability of Dp-D(p + 4) was discussed in [29].…”

When the D(p + 4)-brane (p = 0, 1, 2) with delocalized Dp charges is put into equilibrium with a spherical thermal cavity, the two kinds of charges can be put into canonical or grand canonical ensemble independently by setting different conditions at the boundary. Using the thermal stability condition, we discuss the phase structures of various ensembles of this system formed in this way and find out the situations that the black brane could be the final stable phase in these ensembles. In particular, van der Waals-like phase transitions can happen when D0 and D4 charges are in different kinds of ensembles. Furthermore, our results indicate that the D(p + 4)-branes and the delocalized Dp-branes are equipotent.

Chiral vortical effect from the compactified D4-branes with smeared D0-brane charge

By using the boundary derivative expansion formalism of fluid/gravity correspondence, we study the chiral vortical effect from the compactified D4-branes with smeared D0-brane charge. This background corresponds to a strongly coupled, nonconformal relativistic fluid with a conserved vector current. The presence of the chiral vortical effect is induced by the addition of a Chern-Simons term in the bulk action. Except that the non-dissipative anomalous viscous coefficient and the sound speed rely only on the chemical potential, most of the other thermal and hydrodynamical quantities of the first order depend both on the temperature and the chemical potential. According to our result, the way that the chiral vortical effect coefficient depends on the chemical potential seems irrelevant with whether the relativistic fluid is conformal or not. Stability analysis shows that this anomalous relativistic fluid is stable and the doping of the smeared D0-brane charge will slow down the sound speed.
