1 Tensor Models for Black Hole Probe IAP, Paris, 15th Workshop on Non-Perturbative Quantum Chromodynamics June 12, 2018 Swapnamay Mondal LPTHE, UPMC(Sorbonne Université) (based on arxiv: with Nick Halmagyi)
2 Summary Recently there have been models of near extremal black holes (and possibly examples of NAdS_2/NCFT_1). Such black holes Hawking radiate. Model for a probe interacting with such black holes? We propose a class of tensor models as models of black hole interacting with a probe. Non- trivial features: symmetries of near horizon geometry, black hole (partially) inflicts maximal chaos into the probe.
3 Outline Introduction Our Model Future directions
4 Introduction
5 Near-extremal black holes A. Pattern of symmetry breaking: Near horizon geometry of extremal black holes contains a AdS_2 factor. Near horizon geometry of near-extremal black holes contains a near-ads_2 AdS_2 => Asymptotic symmetries are all reparameterizations of asymptotic boundary circle, but AdS_2 metric preserves only a SL(2, R) subgroup of this. => Spontaneous breaking of reparameterization to SL(2,R). Near AdS_2 => spontaneous and explicit breaking of reparameterization symmetry. B. Maximal Chaos: (Non-extremal) black holes are maximally chaotic systems. explicit breaking of reparameterization symmetry should be related to maximal chaos.

Simplest such tensor model is Carozza-Tanasa-Klebanov- Tarnopolsky (CTKT) Model H CTKT = abc J 4N 3/2 is a real fermion. a,b,c = 1,,N abc ab 0 c 0 a 0 bc 0 a 0 b 0 c

Z large N and deep IR ) J 2 dt G(t 1,t)G(t, t 2 ) 3 = (t 1 t 2 ) Reparameterization symmetry: G(t 1,t 2 )! df (t 1) dt 1 df (t 2 ) dt 2 1/4 G(f(t1 ),f(t 2 )) spontaneously broken down to SL(2,R) by solution G(t) = 1 sgn(t) (4 J 2 ) 1/4 t 1/2

F =(1+K + K )F 0 = 1 1 K F 0 K has an eigenvalue 1, when evaluated in conformal limit. For this eigenspace, K must be evaluated away from conformal limit, thus reparameterization symmetry is explicitly broken.
10 Spectrum of primaries K commutes with SL(2,R) generators. Utilise conformal symmetry: F(t 1,t 2 ; t 3,t 4 )=G (t 12 )G (t 34 )F( ), where = t 12t 34 t 13 t 24 In the limit! 0, F( ) primary of dimension h n ) bulk scalar of mass m 2 n = h n (h n 1) NOT a sparse spectrum. No truncation to SUGRA expected. (see , for discussion on holographic dual) 1X m=1 c 2 m h m
11 A Tensor Model for Black Hole Probe
12 Guessing a probe model Had these tensors been matrices, (which they are not), one would think of the black hole as a bound state of D0 branes and them matrices describing strings stretched between D0 branes. An external D0 brane would be a probe. probes would be described by vectors. Naive tensor analog: probes could be tensors of lower rank.
13 Desirable properties for the Black Hole Probe Probe does not affect the black hole dynamics to leading order. Emergent reparameterization symmetry and the pattern of its breaking should be intact. non trivial because this symmetry is not visible in the Lagrangian. Infliction of maximal chaos.

24 Scorecard Our models satisfy the non trivial requirement of symmetry breaking and partially fulfil that of maximal chaos. Probe spectrum is in natural correspondence with black hole spectrum. Significant improvement for disordered probe model.
25 Future Directions
26 Study thermalisation, i.e. test ETH. Higher point functions.
