Holographic path-integral optimization [PDF]

open access: yesJournal of High Energy Physics, 2021
In this work we elaborate on holographic description of the path-integral optimization in conformal field theories (CFT) using Hartle-Hawking wave functions in Anti-de Sitter spacetimes.

Quantum dynamics using path integral coarse-graining. [PDF]

open access: yesJournal of Chemical Physics, 2022
The vibrational spectra of condensed and gas-phase systems are influenced by thequantum-mechanical behavior of light nuclei. Full-dimensional simulations of approximate quantum dynamics are possible thanks to the imaginary time path-integral (PI ...

Robust Model Predictive Path Integral Control: Analysis and Performance Guarantees [PDF]

open access: yesIEEE Robotics and Automation Letters, 2021
In this letter we propose a novel decision making architecture for Robust Model-Predictive Path Integral Control (RMPPI) and investigate its performance guarantees and applicability to off-road navigation. Key building blocks of the proposed architecture

Smooth Model Predictive Path Integral Control Without Smoothing [PDF]

open access: yesIEEE Robotics and Automation Letters, 2021
We present a sampling-based control approach that can generate smooth actions for general nonlinear systems without external smoothing algorithms. Model Predictive Path Integral (MPPI) control has been utilized in numerous robotic applications due to its

Koopman Operator and Path Integral of Quantum Free-Electron Laser Model

open access: yesMathematics, 2022
A quantum model of a free-electron laser (FEL) is considered. Two different approaches for the exploration of the the FEL system are considered. In the first case, the Heisenberg equations of motion are mapped on the basis of the initial wave functions ...

The path integral of 3D gravity near extremality; or, JT gravity with defects as a matrix integral [PDF]

open access: yes, 2020
We propose that a class of new topologies, for which there is no classical solution, should be included in the path integral of three-dimensional pure gravity, and that their inclusion solves pathological negativities in the spectrum, replacing them with
