Quantum effective actions from nonperturbative worldline dynamics

, 2005
We demonstrate the feasibility of a nonperturbative analysis of quantum field theory in the worldline formalism with the help of an efficient numerical algorithm. In particular, we compute the effective action for a super-renormalizable field theory with

Hadronic corrections to μ-e scattering at NNLO with space-like data

Journal of High Energy Physics, 2019
The Standard Model prediction for μ-e scattering at Next-to-Next-to-Leading Order (NNLO) contains non-perturbative QCD contributions given by diagrams with a hadronic vacuum polarization insertion in the photon propagator.

The Källén-Lehmann representation in de Sitter spacetime

Journal of High Energy Physics, 2023
We study two-point functions of symmetric traceless local operators in the bulk of de Sitter spacetime. We derive the Källén-Lehmann spectral decomposition for any spin and show that unitarity implies its spectral densities are nonnegative.

Nonperturbative effects in heavy quarkonia

, 1994
An effective hamiltonian for heavy quarkonia is derived from QCD by separating gluonic fields in background and quantum fields and neglecting anharmonic contributions. Mesonic states with nonperturbative gluonic components are constructed. These states are invariant under gauge changes of the background fields and form an orthogonal basis.

Theory and modeling of nonperturbative effects in thermoviscous acoustofluidics

Physical Review E, 2023
A theoretical model of thermal boundary layers and acoustic heating in microscale acoustofluidic devices is presented. Based on it, an iterative numerical model is developed that enables numerical simulation of nonlinear thermoviscous effects due to acoustic heating and thermal advection.

Floquet‐Engineered Noise‐Resilient Terahertz Receiver with Modular Phased Array Architecture for Scalable Chip‐Scale Communication

Advanced Photonics Research, EarlyView.
Overcoming the bandwidth, latency, and power constraints of wired interconnects in multicore processing units, this work introduces a terahertz wireless solution featuring a dual‐carrier modular phased‐array transmitter and a novel 2D semiconductor quantum‐well nanoreceiver.

Nonperturbative effects in a scalar supersymmetric theory

Physics Letters B, 1983
Abstract We show that the Parisi-Sourlas argument of dimensionality reduction by two in certain supersymmetric theories holds nonperturbatively, and that topological instanton configurations are important in three dimensions.

Interactions of Neurodegenerative Disease Positron Emission Tomography Imaging Probe Candidates with the C‐Terminus of α‐Synuclein Fibrils

ChemBioChem, EarlyView.
Binding studies of α‐synuclein (αS) fibril ligands using photo‐crosslinking mass spectrometry and Förster resonance energy transfer show that the multiple system atrophy (MSA)‐selective lead, HY‐215, interacts with the αS C‐terminus, unlike Parkinson's disease (PD)‐selective lead, M503. Thus, often‐ignored interactions with the disordered regions of αS
