Numerical Investigations of Holstein Phonons on the Periodic Anderson Model

In condensed matter physics, the idea of localized magnetic moments and the scattering of conduction electrons by those local moments are of central importance not only for explaining the transport of electrons at low temperature region but also for developing the related models and theories to extend our understanding of novel physics like non-conventional superconductor, quantum phase transit...

Path Integral Approach to Noncommutative Spacetimes

We propose a path integral formulation of noncommutative generalizations of spacetime manifold in even dimensions, characterized by a length scale λP . The commutative case is obtained in the limit λP = 0. PACS numbers: 04.60.Gw, 04.60.-m, 02.40-k. ∗E-mail: [email protected]

Model-based Path Integral Stochastic Control: A Bayesian Nonparametric Approach

Over the last few years, sampling-based stochastic optimal control (SOC) frameworks have shown impressive performances in reinforcement learning (RL) with applications in robotics. However, such approaches require a large amount of samples from many interactions with the physical systems. To improve learning efficiency, we present a novel model-based and data-driven SOC framework based on path ...

Quantum Phenomenology with the Path Integral Approach

A quantum measurement model based upon restricted path-integrals allows us to study measurements of generalized position in various one-dimensional systems of phenomenological interest. After a general overview of the method we discuss the cases of a harmonic oscillator, a bistable potential and two coupled systems, briefly illustrating their applications. PACS: 03.65.Bz, 06.30.-k, 74.50.+r

A Path Integral Approach to the Kontsevich Quantization Formula

We give a quantum field theory interpretation of Kontsevich's deformation quantization formula for Poisson manifolds. We show that it is given by the perturbative expansion of the path integral of a simple topological bosonic open string theory. Its Batalin-Vilkovisky quantization yields a superconformal field theory. The associativity of the star product, and more generally the formality conje...
