Holographic zero sound from spacetime-filling branes
We use holography to study sound modes of strongly-interacting conformal field theories with non-zero temperature, T , and U(1) chemical potential, μ. Specifically, we consider charged black brane solutions of Einstein gravity in (3+1)-dimensional Anti ...

Poincaré constraints on celestial amplitudes
The functional structure of celestial amplitudes as constrained by Poincare symmetry is investigated in 2, 3, and 4-point cases for massless external particles of various spin, as well as massive external scalars.

Integrated massive vertex operator in pure spinor formalism
We construct the integrated vertex operator for the first massive states of open superstrings with (mass)2 = 1/α ′ in the pure spinor formalism of the superstring theory. This vertex operator is expressed in terms of the ten dimensional N = 1 $$ \mathcal{

Forward charm-production models and prompt neutrinos at IceCube
We investigate the prompt neutrino background at IceCube, as determined from forward charm. We consider the role of intrinsic charm and of a recombination model and show that the contribution of these mechanisms is at most a factor two.

Is the EMI model a QFT? An inquiry on the space of allowed entropy functions
The mutual information I(A, B) of pairs of spatially separated regions satisfies, for any d-dimensional CFT, a set of structural physical properties such as positivity, monotonicity, clustering, or Poincaré invariance, among others.

Hydroxyethyl starch 130/0.42 versus Ringer's acetate in severe sepsis.
BACKGROUND Hydroxyethyl starch (HES) [corrected] is widely used for fluid resuscitation in intensive care units (ICUs), but its safety and efficacy have not been established in patients with severe sepsis.

Dynamics of N5+-H electron capture in Debye plasmas
The electron capture in N5+-H collisions imbedded in a Debye plasma is studied by using the two-center atomic orbital close-coupling method in the energy range from 1 keV/u to 200 keV/u.

Emergent geometry through quantum entanglement in Matrix theories
In the setting of the Berenstein-Maldacena-Nastase Matrix theory, dual to light-cone M-theory in a PP-wave background, we compute the Von Neumann entanglement entropy between a probe giant graviton and a source.
