Path integral optimization for TT¯ deformation [PDF]
Physical Review D, 2019 We use the path integral optimization approach of Caputa, kundu, Miyaji, Takayanagi and Watanabe to find the time slice of geometries dual to vacuum, primary and thermal states in the $T\bar{T}$ deformed two dimensional CFTs.

Path-integral complexity for perturbed CFTs [PDF]
Journal of High Energy Physics, 2018 In this work, we formulate a path-integral optimization for two dimensional conformal field theories perturbed by relevant operators. We present several evidences how this optimization mechanism works, based on calculations in free field theories as well

Harmonic Path Integral Diffusion
IEEE AccessHarmonic Path Integral Diffusion (H-PID) introduces a novel approach to sampling from complex, continuous probability distributions by creating a time-dependent “bridge” from an initial point to the target distribution.

Edge dynamics from the path integral — Maxwell and Yang-Mills [PDF]
Journal of High Energy Physics, 2018 A bstractWe derive an action describing edge dynamics on interfaces for gauge theories (Maxwell and Yang-Mills) using the path integral. The canonical structure of the edge theory is deduced and the thermal partition function calculated. We test the edge

DISCRETIZATION OF THE SUPERPARTICLE PATH INTEGRAL [PDF]
Modern Physics Letters A, 1993 We investigate the hitherto unexplored relation between the superparticle path integral and superfield theory. Requiring that the path integral has the global symmetries of the classical action and obeys the natural composition property of path integrals, and also that the discretized action has the correct naive continuum limit, we find a viable ...

Path integral approach to random neural networks [PDF]
Physical Review E, 2018 In this work we study of the dynamics of large-size random neural networks. Different methods have been developed to analyze their behavior, and most of them rely on heuristic methods based on Gaussian assumptions regarding the fluctuations in the limit ...

Effective diffusion of a tracer in active bath: A path-integral approach
National Science OpenWe investigate the effective diffusion of a tracer immersed in an active particle bath consisting of self-propelled particles. Utilising the Dean's method developed for the equilibrium bath and extending it to the nonequilibrium situation, we derive a ...

Principles of Insect Path Integration [PDF]
Current Biology, 2018 Continuously monitoring its position in space relative to a goal is one of the most essential tasks for an animal that moves through its environment. Species as diverse as rats, bees, and crabs achieve this by integrating all changes of direction with the distance covered during their foraging trips, a process called path integration.

Path integrals of the vector field: Covariance of a path integral
Progress of Theoretical and Experimental Physics, 2019 On the basis of the canonical quantization procedure of a system defined on a cubic lattice, we propose a new method, in which resolutions of unity expressed in terms of eigenvectors are naturally provided, to find eigenvectors of field operators. By making use of fundamental ingredients thus obtained, we derive time sliced path integral formulae for a
