New developments in the numerical conformal bootstrap

S Rychkov, N Su - Reviews of Modern Physics, 2024 - APS
Over the past 15 years, the numerical conformal bootstrap has become an indispensable
tool for studying strongly coupled conformal field theories in various dimensions. Reviewed …

Matrix-model simulations using quantum computing, deep learning, and lattice monte carlo

E Rinaldi, X Han, M Hassan, Y Feng, F Nori… - PRX Quantum, 2022 - APS
Matrix quantum mechanics plays various important roles in theoretical physics, such as a
holographic description of quantum black holes, and it underpins the only practical …

[PDF][PDF] Snowmass White Paper: The Numerical Conformal Bootstrap

D Poland, D Simmons-Duffin - arXiv preprint arXiv:2203.08117, 2022 - arxiv.org
The idea of the conformal bootstrap is to constrain and solve CFTs using physical
consistency conditions like symmetry, unitarity, and causality. By relying on nonperturbative …

Analytic and numerical bootstrap for one-matrix model and “unsolvable” two-matrix model

V Kazakov, Z Zheng - Journal of High Energy Physics, 2022 - Springer
A bstract We propose the relaxation bootstrap method for the numerical solution of multi-
matrix models in the large N limit, developing and improving the recent proposal of H. Lin. It …

Bootstrap bounds on D0-brane quantum mechanics

HW Lin - Journal of High Energy Physics, 2023 - Springer
A bstract We derive simple bootstrap bounds on correlation functions of the BFSS matrix
theory/D0-brane quantum mechanics. The result strengthens and extends Polchinski's virial …

Lower Bounds on Ground-State Energies of Local Hamiltonians through the Renormalization Group

I Kull, N Schuch, B Dive, M Navascués - Physical Review X, 2024 - APS
Given a renormalization scheme, we show how to formulate a tractable convex relaxation of
the set of feasible local density matrices of a many-body quantum system. The relaxation is …

[HTML][HTML] Numerical bootstrap in quantum mechanics

J Bhattacharya, D Das, SK Das, AK Jha, M Kundu - Physics Letters B, 2021 - Elsevier
We study the effectiveness of the numerical bootstrap techniques recently developed in [1]
for quantum mechanical systems. We find that for a double well potential the bootstrap …

Matrix Theory Reloaded: A BPS Road to Holography

CDA Blair, J Lahnsteiner, NA Obers, Z Yan - arXiv preprint arXiv …, 2024 - arxiv.org
We revisit the decoupling limits that lead to matrix theories on D-branes. We highlight the
BPS nature of these limits, in which the target space geometry becomes non-Lorentzian and …

Bootstrapping the gap in quantum spin systems

CO Nancarrow, Y Xin - Journal of High Energy Physics, 2023 - Springer
A bstract In this work we report on a new bootstrap method for quantum mechanical
problems that closely mirrors the setup from conformal field theory (CFT). We use the …

Semidefinite programming algorithm for the quantum mechanical bootstrap

D Berenstein, G Hulsey - Physical Review E, 2023 - APS
We present a semidefinite programming algorithm to find eigenvalues of Schrödinger
operators within the bootstrap approach to quantum mechanics. The bootstrap approach …
