The Interplay of Magnetic Order with the Electronic Scattering and Crystal‐Field Effects in a Metallic Ferromagnet

open access: yesAdvanced Science, EarlyView.
The interplay between magnetic ordering and crystal electric field (CEF) excitations plays a pivotal role in defining the low‐energy electrodynamics of quantum materials. By probing the temperature‐dependent THz conductivity in a rare‐earth‐based metallic ferromagnet, we uncover a microscopic connection between localized and itinerant electrons ...

Nested Selves: Self‐Organization and Shared Markov Blankets in Prenatal Development in Humans

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract The immune system is a central component of organismic function in humans. This paper addresses self‐organization of biological systems in relation to—and nested within—other biological systems in pregnancy. Pregnancy constitutes a fundamental state for human embodiment and a key step in the evolution and conservation of our species. While not

An improved $\eps$ expansion for three-dimensional turbulence: two-loop renormalization near two dimensions

open access: yes, 2004
An improved $\eps$ expansion in the $d$-dimensional ($d > 2$) stochastic theory of turbulence is constructed at two-loop order which incorporates the effect of pole singularities at $d \to 2$ in coefficients of the $\eps$ expansion of universal ...

Defect‐Free Sb‐Doping in Bi2O2Se Achieves Two‐Order‐of‐Magnitude Reduction in Saturation Intensity While Preserving High Carrier Mobility

open access: yesAdvanced Science, EarlyView.
This study demonstrates defect‐free states Sb3⁺ doping in Bi2O2Se, enhancing carrier mobility while reducing saturation intensity by about two orders of magnitude. First‐principles calculations and experiments reveal optimized electronic structure and improved nonlinear response.

Assessing the Effect of Large Igneous Provinces on Global Oceanic Redox Conditions Using Non‐traditional Metal Isotopes (Molybdenum, Uranium, Thallium)

open access: yesGeophysical Monograph Series, Page 305-323., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Unqueched Kogut-Susskind quark propagator in Lattice Landau Gauge QCD

open access: yes, 2005
Quark propagators of the unquenched Kogut-Susskind(KS) fermion obtained from the gauge configurations of the MILC collaboration are measured after Landau gauge fixing and using the Staple+Naik action.

Gauge Theories on Deformed Spaces

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2010
The aim of this review is to present an overview over available models and approaches to non-commutative gauge theory. Our main focus thereby is on gauge models formulated on flat Groenewold-Moyal spaces and renormalizability, but we will also review ...

Wafer‐Scale Bandgap‐Tunable MoS2/PbS Phototransistors Enabled by Solution Processing

open access: yesAdvanced Science, EarlyView.
This work advances bandgap‐tunable MoS2/PbS phototransistors by introducing lateral heterojunctions, which enable superior tunable bandgap (1.24–0.61 eV) via Type‐II alignment. Plasma‐enhanced solution processing ensures uniform 4‐inch wafer‐scale fabrication with 97% yield.

Rota-Baxter Algebras in Renormalization of Perturbative Quantum Field Theory

open access: yes, 2006
Recently, the theory of renormalization in perturbative quantum field theory underwent some exciting new developments. Kreimer discovered an organization of Feynman graphs into combinatorial Hopf algebras.
