Query: Exotic Multi-quark States in the Deconfined Phase from Gravity Dual
  Models   In the deconfined phase of quark-gluon plasma, it seems that most of the
quarks, antiquarks and gluons should be effectively free in the absence of the
linear confining potential. However, the remaining Coulomb-type potential
between quarks in the plasma could still be sufficiently strong that certain
bound states, notably of heavy quarks such as $J/\psi$ are stable even in the
deconfined plasma up to a certain temperature. Baryons can also exist in the
deconfined phase provided that the density is sufficiently large.
  We study three kinds of exotic multi-quark bound states in the deconfined
phase of quark-gluon plasma from gravity dual models in addition to the normal
baryon. They are $k$-baryon, $(N+\bar{k})$-baryon and a bound state of $j$
mesons which we call "$j$-mesonance". Binding energies and screening lengths of
these exotic states are studied and are found to have similar properties to
those of mesons and baryons at the leading order. Phase diagram for the exotic
nuclear phases is subsequently studied in the Sakai-Sugimoto model. Even though
the exotics are less stable than normal baryons, in the region of high chemical
potential and low temperature, they are more stable thermodynamically than the
vacuum and chiral-symmetric quark-gluon plasma phases ($\chi$S-QGP).
