Some rigorous results on symmetry breakings in gauge QFT
SciPost Physics Proceedings, 2022 The extraordinary success of the Standard Model asks for a more rigorous control beyond the perturbative approach, which is affected by mathematical problems (interaction picture and canonical quantization, non-covergence of the perturbative series ...

Corrections of Electron–Phonon Coupling for Second‐Order Structural Phase Transitions
physica status solidi (b), EarlyView.The left image illustrates a weak electron–phonon coupling, while the right image depicts a strong electron–phonon coupling. The weak electron–phonon coupling interaction between the lattice and electrons is susceptible to destabilization by an increase in temperature.

Canonical quantization of electromagnetic field in an anisotropic polarizable and magnetizable medium [PDF]
, 2008 A fully canonical quantization of electromagnetic field is introduced in the presence of an anisotropic polarizable and magnetizable medium. Two tensor fields which couple the electromagnetic field with the medium and have an important role in this ...

High‐resolution X‐ray scanning with a diffuse Huffman‐patterned probe to reduce radiation damage
Journal of Synchrotron Radiation, EarlyView.This paper introduces high‐resolution imaging using diffuse probes, which allow for lower energy deposition per unit area per unit time, by encoding Huffman‐like patterns onto them, enabling a tighter impulse response. The approach, demonstrated in X‐ray imaging, involves using specially fabricated masks to shape the probe and recover sharp object ...

Canonical quantization of gauge fields in static space-times with applications to Rindler spaces [PDF]
, 2008 The canonical quantization in the Weyl gauge of gauge fields in static space-times is presented. With an appropriate definition of transverse and longitudinal components of gauge fields, the Gauss law constraint is resolved explicitly for scalar and ...

Path-integral quantization of tensionless (super) string
Journal of High Energy Physics, 2023 In this work, we study the tensionless (super)string in the formalism of path-integral quantization. We introduce BMS bc and βγ ghosts intrinsically by accounting for the Faddeev-Popov determinants appeared in fixing the gauges.

Universe, 2021 The goal of this contribution is to present the properties of a class of quantum bouncing models in which the quantum bounce originates from the Dirac canonical quantization of a midi-superspace model composed of a homogeneous and isotropic background ...

Survey on Modeling of Human‐made Articulated Objects
Computer Graphics Forum, EarlyView.Abstract 3D modeling of articulated objects is a research problem within computer vision, graphics, and robotics. Its objective is to understand the shape and motion of the articulated components, represent the geometry and mobility of object parts, and create realistic models that reflect articulated objects in the real world.

A Note on canonical quantization of fields on a manifold [PDF]
, 2008 We propose a general construction of quantum states for linear canonical quantum fields on a manifold, which encompasses and generalizes the ``standard'' procedures existing in textbooks. Our method provides pure and mixed states on the same footing.
