Magnetization and Polarization of Coupled Nuclear Spins Ensembles at High Magnetic Fields

open access: yesChemPhysChem, EarlyView.
Herein, the magnetization of spins at high magnetic fields using various theoretical approaches is analyzed. The theorem is rigorously proved that the magnetization of individual spins is equivalent to the magnetization of coupled spins within a molecule.

Resurgence in the scalar quantum electrodynamics Euler–Heisenberg Lagrangian

open access: yesEuropean Physical Journal C: Particles and Fields
We explore the ideas of resurgence and Padé–Borel resummation in the Euler–Heisenberg Lagrangian of scalar quantum electrodynamics, which has remained largely unexamined in these contexts.

Electrochemical Biosensors for Cancer Biomarker Detection: Basic Concept, Design Strategy and Cutting‐Edge Development

open access: yesElectrochemical Science Advances, EarlyView.
ABSTRACT Cancer is a result of uncontrolled cell growth with the potential to damage or spread to another part of the body. It is the deadliest disease in the world; therefore, rapid and sensitive detection is essential to fight it. In the past few decades, many diagnosis tools have been developed to detect cancer and monitor therapy progress.

Time-Dependent Effective Hamiltonians for Light–Matter Interactions

open access: yesEntropy
In this paper, we present a systematic approach to building useful time-dependent effective Hamiltonians in molecular quantum electrodynamics. The method is based on considering part of the system as an open quantum system and choosing a convenient ...

Easy-plane QED3’s in the large N f limit

open access: yesJournal of High Energy Physics, 2019
We consider Quantum Electrodynamics in 2 + 1 dimensions with N f fermionic or bosonic flavors, allowing for interactions that respect the global symmetry U(N f /2)2. There are four bosonic and four fermionic fixed points, which we analyze using the large
