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

Journal 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

Influence of Nanoparticles on Dielectric Properties of High‐Voltage Epoxy‐Based Nanocomposite Insulators: Simulation and Experimental Analysis

Energy Science &Engineering, EarlyView.
ABSTRACT There is a need to develop an improved insulating material that surpasses traditional insulators in terms of insulation and efficient operation under extreme weather conditions. Epoxy nanocomposites (NCs) have gained considerable attention due to their intrinsic material properties.

Time-Dependent Effective Hamiltonians for Light–Matter Interactions

Entropy
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 ...

Relational Bundle Geometric Formulation of Non‐Relativistic Quantum Mechanics

Fortschritte der Physik, EarlyView.
Abstract A bundle geometric formulation of non‐relativistic many‐particles Quantum Mechanics is presented. A wave function is seen to be a C$\mathbb {C}$‐valued cocyclic tensorial 0‐form on configuration space‐time seen as a principal bundle, while the Schrödinger equation flows from its covariant derivative, with the action functional supplying a ...

Experimentally simulating the dynamics of quantum light and matter at deep-strong coupling

Nature Communications, 2017
Realising deep-strong coupling phenomena for interacting light-matter systems remains an experimental challenge. Here, Langford et al. employ a circuit quantum electrodynamics chip with moderate coupling between a resonator and transmon qubit to realise ...

SOLEY: A Package for Optical and Extended Detailed Balance Model for Photovoltaic Device Simulation

Solar RRL, EarlyView.
SOLEY is a graphical user interface (GUI)‐based simulation package for photovoltaic cells. It combines optical modeling using the Transfer Matrix Method, and device modeling using an extension of the detailed balance model, which considers various recombination mechanisms, including Shockley–Read–Hall.

Interaction Induced Quantum Valley Hall Effect in Graphene

Physical Review X, 2015
We use pseudo-quantum electrodynamics in order to describe the full electromagnetic interaction of the p electrons in graphene in a consistent 2D formulation.

To B or not to B: primordial magnetic fields from Weyl anomaly

Journal of High Energy Physics, 2018
The quantum effective action for the electromagnetic field in an expanding universe has an anomalous dependence on the scale factor of the metric arising from virtual charged particles in the loops.

The simplicity of physical laws

Noûs, EarlyView.
Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.
