“…Our final answer (1.2) includes both the KK electric field and a gravitational acceleration a. It is instructive to compare this result with the known rate [20] for Schwinger pair production in an accelerated frame, as quoted in eqn (B.4) in the Appendix. Since in our case a is bounded below by E/2, we can only directly compare the two answers in the limit of small electric field.…”

We study Schwinger pair creation of charged Kaluza-Klein particles from a static KK electric field. We find that the gravitational backreaction of the electric field on the geometry -which is incorporated via the electric KK Melvin solution -prevents the electrostatic potential from overcoming the rest mass of the KK particles, thus impeding the tunneling mechanism which is often thought of as responsible for the pair creation. However, we find that pair creation still occurs with a finite rate formally similar to the classic Schwinger result, but via an apparently different mechanism, involving a combination of the Unruh effect and vacuum polarization due to the E-field.

“…Depending on the sign of j, this corresponds to the tunneling of a long string coming from Rindler infinity into a short string going forward (j < 0) or backward (j > 0) in time. The wave functions U j in,R and V j in,R introduced in [14,26] can now be interpreted as operators creating a long string stretching from infinity, resp. a short string stretching into the horizon.…”

As in the Schwinger effect, tunneling corresponds to induced pair production, and implies that spontaneous pair production takes place as well.…”

Misner space, also known as the Lorentzian orbifold R 1,1 /boost, is one of the simplest examples of a cosmological singularity in string theory. In this work, the study of weakly coupled closed strings on this space is pursued in several directions: (i) physical states in the twisted sectors are found to come in two kinds: short strings, which wind along the compact space-like direction in the cosmological (Milne) regions, and long strings, which wind along the compact time-like direction in the (Rindler) whiskers. The latter can be viewed as infinitely long static open strings, stretching from Rindler infinity to a finite radius and folding back onto themselves. (ii) As in the Schwinger effect, tunneling between these states corresponds to local pair production of winding strings. The tunneling rate approaches unity as the winding number w gets large, as a consequence of the singular geometry. (iii) The one-loop string amplitude has singularities on the moduli space, associated to periodic closed string trajectories in Euclidean time. In the untwisted sector, they can be traced to the combined existence of CTCs and Regge trajectories in the spectrum. In the twisted sectors, they indicate pair production of winding strings. (iv) At a classical level and in sufficiently low dimension, the condensation of winding strings can indeed lead to a bounce, although the required initial conditions are not compatible with Misner geometry at early times. (v) The semi-classical analysis of winding string pair creation can be generalized to more general (off-shell) geometries. We show that a regular geometry regularizes the divergence at large winding number. * Incumbent of the Recanati career development chair for energy research

From color glass condensate to quark–gluon plasma through the event horizon

We propose a new thermalization scenario for heavy ion collisions which at sufficiently high energies implies the phase transition to the quark-gluon plasma. The key ingredient of our approach is the Hawking-Unruh effect: an observer moving with an acceleration a experiences the influence of a thermal bath with an effective temperature T = a/2π, similar to the one present in the vicinity of a black hole horizon. For electric charges moving in external electromagnetic fields of realistic strength, the resulting temperature appears too small to be detected. However for partons in strong color fields the effect should be observable: in the Color Glass Condensate picture, the strength of the color-electric field is E ∼ Q 2 s /g (Q s is the saturation scale, and g is the strong coupling), the typical acceleration is a ∼ Q s , and the heat bath temperature is T = Q s /2π ∼ 200 MeV. In nuclear collisions at sufficiently high energies the effect can induce a rapid thermalization over the time period of τ ≃ 2π/Q s ≃ 1 fm accompanied by phase transitions. We consider a specific example of chiral symmetry restoration induced by a rapid deceleration of the colliding nuclei. We argue that parton saturation in the initial nuclear wave functions is a necessary pre-condition for the formation of quark-gluon plasma. We discuss the implications of our "black hole thermalization" scenario for various observables in relativistic heavy ion collisions.2
