Clean‐Limit 2D Superconductivity in a Thick Exfoliated Kagome Film

Advanced Functional Materials, EarlyView.
This study reports clean‐limit 2D superconductivity in a thick kagome system, analogous to the 3D case. It observes a drop in superfluid stiffness near the superconducting transition and a cusp‐like feature in the angular dependence of the upper critical field.

LHC phenomenology of supersymmetric models beyond the MSSM [PDF]

, 2010
We discuss various phenomenological aspects of supersymmetric models beyond the MSSM. A particular focus is on models which can correctly explain neutrino data and the possiblities of LHC to identify the underlying scenario.Comment: Contribution to the ...

Quantifying Spin Defect Density in hBN via Raman and Photoluminescence Analysis

Advanced Functional Materials, EarlyView.
An all‐optical method is presented for quantifying the density of boron vacancy spin defects in hexagonal boron nitride (hBN). By correlating Raman and photoluminescence signals with irradiation fluence, defect‐induced Raman modes are identified and established an relationship linking optical signatures to absolute defect densities. This enables direct

Simplified TeV leptophilic dark matter in light of DAMPE data

Journal of High Energy Physics, 2018
Using a simplified framework, we attempt to explain the recent DAMPE cosmic e + + e − flux excess by leptophilic Dirac fermion dark matter (LDM). The scalar (Φ0) and vector (Φ1) mediator fields connecting LDM and Standard Model particles are discussed ...

Phenomenological Aspects of Heterotic Orbifold Models at One Loop

, 2003
We provide a detailed study of the phenomenology of orbifold compactifications of the heterotic string within the context of supergravity effective theories.

Unified dark energy models : a phenomenological approach [PDF]

, 2004
A phenomenological approach is proposed to the problem of universe accelerated expansion and of the dark energy nature. A general class of models is introduced whose energy density depends on the redshift $z$ in such a way that a smooth transition among ...

Superconformal technicolor: Models and phenomenology

Physical Review D, 2012
In supersymmetric theories with a strong conformal sector, soft supersymmetry breaking naturally gives rise to confinement and chiral symmetry breaking in the strong sector at the TeV scale. We construct and analyze models where such a sector dynamically breaks electroweak symmetry, and take the first steps in studying their phenomenology.

The Dynamics of Interfacial Trap States in High‐Detectivity Near‐Infrared Photomultiplication Organic Photodetectors

Advanced Functional Materials, EarlyView.
Photomultiplication organic photodetectors (PM OPDs) are an attractive strategy for health‐monitoring. Here, PM‐OPDs are reported with a specific detectivity of 5.7 × 1012 Jones and external quantum efficiency values of 3500% under −10 V. The dynamics of carrier trapping in these devices are elucidated through trap selective spectroscopical techniques.

Correlation between R D ∗ $$ {R}_{D^{\left(\ast \right)}} $$ and top quark FCNC decays in leptoquark models

Journal of High Energy Physics, 2019
Some interpretations of R D ∗ $$ {R}_{D^{\left(\ast \right)}} $$ anomaly in B meson decay using leptoquark (LQ) models can also generate top quark decays through Flavor Changing Neutral Current (FCNC). In this work we focus on two LQs, i.e.

Extract the energy scale of anomalous γγ → W + W − scattering in the vector boson scattering process using artificial neural networks

Journal of High Energy Physics, 2021
As a model independent approach to search for the signals of new physics (NP) beyond the Standard Model (SM), the SM effective field theory (SMEFT) draws a lot of attention recently. The energy scale of a process is an important parameter in the study of
