Gauge and unitary transformations in multipolar quantum optics.
Philos Trans A Math Phys Eng Sci
December 2024
Multipolar quantum optics deals with the interaction of light with matter as a many-body bound system of charged particles where the coupling to electromagnetic fields is in terms of the multipolar electric polarization and magnetization. We describe two transformations applied to the conventional non-relativistic formalism, namely a gauge transformation applied directly to the fields at the Lagrangian stage and a unitary transformation applied to the old Hamiltonian. We show how such transformations lead to the same Power-Zienau-Woolley (PZW) formulation of the quantum electrodynamics (QED) of an overall electrically neutral many-body bound system of charges, including the internal motion as well as the gross dynamics of the centre of mass.

Materials And Methods: For the present study, twelve mature male camels were employed. Following the animals breeding and non-breeding seasons of slaughter under official licensing and veterinary supervision, samples were obtained from various regions of the ductus deferens and prostate gland and processed using general histology and immunohistochemical methods.
Article Synopsis
- The study aimed to assess how sonography can help identify and characterize complications after liver transplants using gray scale and color Doppler imaging.
- Conducted at Prince Sultan Military Medical City, the research involved analyzing the medical records of 122 liver transplant patients, mainly middle-aged males with hepatitis B and liver cancer as common reasons for surgery.
- Results indicated that biliary and vascular complications were prevalent post-transplant, with portal vein thrombosis being particularly significant, while normal Doppler findings stabilized within a week after surgery, emphasizing the importance of ultrasound in monitoring graft health.
Induction of labor (IOL) has become a common practice in obstetrics, leading to an increase in antenatal admissions and workload. This review aims to explore the available options for outpatient IOL and their effectiveness. We conducted an electronic search for trials on Cochrane, PubMed, Google Scholar, and Web of Science databases for randomized control trials (RCTs) comparing inpatient and outpatient labor induction and covering the period until 2024.
