Aspects of the bulk flat space limit in AdS/CFT
David Berenstein, Joan Simon
The flat space limit of scalar bulk fields in AdS is discussed within a Lorentzian canonical quantization setup tailored to describe AdS state preparation and to extract the flat S…
The endpoint of partial deconfinement
David Berenstein, Kai Yan
We study the matrix quantum mechanics of two free hermitian matrices subject to a singlet constraint in the microcanonical ensemble. This is the simplest example of a t…
Integrable Spin Chains from large- QCD at strong coupling
David Berenstein, Hiroki Kawai
We study a spin chain for a confining string that arises at first order in degenerate perturbation from the strong-coupling expansion of the Kogut-Susskind Hamiltonian on a square…
One-dimensional reflection in the quantum mechanical bootstrap
David Berenstein, George Hulsey
We describe the application of the quantum mechanical bootstrap to the solution of one-dimensional scattering problems. By fixing a boundary and modulating the Robin parameter of t…
Chaotic LLM billiards
David Berenstein, Elliot Maderazo, Robinson Mancilla +1
We study null geodesics of the ten-dimensional LLM geometries. In particular, we show that there are a subset of these null geodesics that are confined to the LLM plane. The effect…
Staggered bosons
David Berenstein
A model with a half boson degree of freedom per lattice site in one dimension is developed. The boson is protected from developing a gap by translation symmetry: while the left mov…
Aspects of thermal one-point functions and response functions in AdS Black holes
David Berenstein, Robinson Mancilla
We revisit the problem of analytically computing the one point functions for scalar fields in planar AdS black holes of arbitrary dimension, which are sourced by the Weyl squared t…
A Semidefinite Programming algorithm for the Quantum Mechanical Bootstrap
David Berenstein, George Hulsey
We present a semidefinite program (SDP) algorithm to find eigenvalues of Schrödinger operators within the bootstrap approach to quantum mechanics. The bootstrap approach involves t…
Anomalous Bootstrap on the half line
David Berenstein, George Hulsey
We study carefully the problem of the bootstrap on the half line. We show why one needs the full set of constraints derived from the Stieltjes theorem on the moment problem by reex…
Aspects of Holography in Conical
David Berenstein, David Grabovsky, Ziyi Li
We study the Feynman propagator of free scalar fields in with a conical defect. The propagator is built by solving the bulk equation of motion, summing over the modes of th…
BPS coherent states and localization
David Berenstein, Shannon Wang
We introduce coherent states averaged over a gauge group action to study correlators of half BPS states in SYM theory. The overlaps of these averaged coherent states…
String junctions suspended between giants
David Berenstein, Adolfo Holguin
We construct string junction solutions suspended between both sphere and AdS giant gravitons in . Our results extend easily to more general half BPS geomet…
U(1) Fields from Qubits: an Approach via D-theory Algebra
David Berenstein, Richard Brower, Hiroki Kawai
A new quantum link microstructure was proposed for the lattice quantum chromodynamics (QCD) Hamiltonian, replacing the Wilson gauge links with a bilinear of fermionic qubits, later…
Operator product expansions and recoil
David Berenstein, Ruwanmali Bernadette de Zoysa
Some issues of recoil effects in AdS/CFT are studied from the point of view of OPE expansions for generalized free fields. We show that the conformal group structure encodes the re…
Bootstrapping Simple QM Systems
David Berenstein, George Hulsey
We test the bootstrap approach for determining the spectrum of one dimensional Hamiltonians, following the recent approach of Han, Hartnoll, and Kruthoff. We focus on comparing the…

David Berenstein, George Hulsey
We test the bootstrap approach for determining the spectrum of one dimensional Hamiltonians. In this paper we focus on problems that have a two parameter search space in the bootst…

David Berenstein, Yueshu Guan
We study real time classical matrix mechanics of a simplified matrix model inspired by the black hole evaporation problem. This is a step towards making a quantitative…
The Tortoise and the Hare: A Causality Puzzle in AdS/CFT
David Berenstein, David Grabovsky
We pose and resolve a holographic puzzle regarding an apparent violation of causality in AdS/CFT. If a point in the bulk of moves at the speed of light, the boundary subregio…

David Berenstein, Adolfo Holguin
We compute sigma model solutions for rigidly rotating open strings suspended between giant gravitons in general LLM geometries. These solutions are confined to the LLM plane. These…

We study stable circular orbits in spherically symmetric AdS black holes in various dimensions and their limiting innermost stable circular orbits (ISCOs). We provide analytic expr…

We study classical solutions to the Nambu-Goto string on and corresponding to strings stretched between wrapped branes extending in . The…
Localized states in global AdS
David Berenstein, Joan Simon
We construct both local states and scattering states with finite energy in global AdS by inserting properly regularized operators in the CFT of arbitrary conformal dimension …
Quenches on thermofield double states and time reversal symmetry
David Berenstein
In this paper we study a quench protocol on thermofield double states in the presence of time-reversal symmetry that is inspired by the work of Gao, Jafferis and Wall. The deformat…
Gauged fermionic matrix quantum mechanics
David Berenstein, Robert de Mello Koch
We consider the gauged free fermionic matrix model, for a single fermionic matrix. In the large limit this system describes a chiral fermion in dimensions. The Ga…
