Mechanism for fluctuating pair density wave

Nature Communications, 2023
In weakly coupled BCS superconductors, only electrons within a tiny energy window around the Fermi energy, E F , form Cooper pairs. This may not be the case in strong coupling superconductors such as cuprates, FeSe, SrTiO3 or cold atom condensates where ...

Gauge coupling unification in E 6 F-theory GUTs with matter and bulk exotics from flux breaking

, 2013
We consider gauge coupling unification in E 6 F-Theory Grand Unified Theories (GUTs) where E 6 is broken to the Standard Model (SM) gauge group using fluxes. In such models there are two types of exotics that can affect gauge coupling unification, namely

E6 models from F-theory

, 2013
F-theory is a non-perturbative formulation of type IIB superstring theory which allows for the decoupling of gravity and for the formulation of GUT theories based on the gauge group E 6.

Converse magnetoelectric coupling in [(CH3)2NH2]Ni(HCOO)3 revealed by electron spin resonance [PDF]

APL Materials
Electric-field (E) control of magnetism provides a direct route toward low power spin-based technologies by tuning magnetic states without current-driven dissipation.

Can we avoid high coupling?

, 2011
It is considered good software design practice to organize source code into modules and to favour within-module connections (cohesion) over between-module connections (coupling), leading to the oft-repeated maxim "low coupling/high cohesion".

Study on coupling coordination and collaborative optimization system of water-energy-grain

Frontiers in Ecology and Evolution, 2022
In order to solve the problem that water resources in a certain province are relatively scarce and the spatial matching effect of resources is poor, which causes the w-e-f system to face the problem of trade-off, the water-energy-food coupling ...

Investigation into the earliest generation of medium-scale traveling ionospheric disturbances with electrodynamic signatures using dense GNSS observations over Japan

Earth, Planets and Space
Understanding the earliest formation stages of medium-scale traveling ionospheric disturbances (MSTIDs) with electrodynamic signatures (commonly referred to as nighttime MSTIDs) is essential for comprehending their full development.

Higgs boson production and decay at e+e− colliders as a probe of the Left–Right twin Higgs model

Nuclear Physics B, 2015
In the framework of the Left–Right twin Higgs (LRTH) model, we consider the constrains from the latest search for high-mass dilepton resonances at the LHC and find that the heavy neutral boson ZH is excluded with mass below 2.76 TeV.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Unitarity implications of $$\tilde{F}_{\mu \nu }$$ F ~ μ ν and $$F_{\mu \nu }$$ F μ ν models with Lorentz invariance violation in $$e^{+}e^{-} \rightarrow \mu ^{+}\mu ^{-}$$ e + e - → μ + μ -

European Physical Journal C: Particles and Fields
We studied two different models that included Lorentz Invariance Violation coupling in the scattering processes of $$e^+e^- \rightarrow \mu ^+\mu ^-$$ e + e - → μ + μ - . We found that using the model with the dual electromagnetic tensor $$\tilde{F}_{\mu
