Defect Analysis of the β– to γ–Ga2O3 Phase Transition
Advanced Functional Materials, EarlyView.The role of defects at all the relevant stages of the β$\beta$‐ to γ$\gamma$‐Ga2O3 polymorph transition is investigated using a multi method approach. The positron annihilation spectroscopy based results show that the defect density decreases after the transition, and that changes in defect configuration within the γ phase occur with increasing ...

Test of the Skyrme Effective Field Theory Using Quenched Lattice QCD
, 1993 The Skyrme effective field theory is tested by evaluating nucleon ground state matrix elements of the correlation functions for two flavor density operators and two pseudoscalar density operators in the Skyrme model and comparing them with results in ...

Advanced Functional Materials, EarlyView.Halide diffusion limits the stability of hybrid halide perovskites for optoelectronic applications and thus needs to be quantified. This study presents an effective interdiffusion model to obtain time‐dependent diffusion coefficients for I− and Br− diffusion from in situ X‐ray diffraction data during the formation of a solid solution MAPbIxBr3‐x from ...

Symmetry and scaling in the Q-exact lattice (2,2) 2d Wess-Zumino model
, 2005 As a nonperturbative check on the Q-exact lattice formulation, we demonstrate that the continuum R-symmetries are recovered. We locate the critical domain of the lattice theory.

Large Anomalous and Topological Hall Effect and Nernst Effect in a Dirac Kagome Magnet Fe3Ge
Advanced Functional Materials, EarlyView.Fe3Ge, a Kagome‐lattice magnet, exhibits remarkable anomalous Hall and Nernst effects, with transverse thermoelectric conductivity surpassing or comaprable to some well‐known ferromagnets. First‐principles calculations attribute these to Berry curvature from massive Dirac gaps. Additionally, topological Hall and Nernst signals emerge from field‐induced

Magnetic‐Field Dependent VB− Spin Decoherence in Hexagonal Boron Nitrides: A First‐Principles Study
Advanced Functional Materials, EarlyView.This study investigates the decoherence of the VB− defect in h‐BN under external magnetic fields using first‐principles quantum many‐body simulations. A transition boundary distinguishing distinct decoherence regimes is identified, with its dependence on isotopic composition.

Supermultiplets in N=1 SUSY SU(2) Yang-Mills Theory
, 2017 We study $\mathcal{N}=1$ supersymmetric Yang-Mills theory (SYM) on the lattice. The non-perturbative nature of supersymmetric field theories is still largely unknown. Similarly to QCD, SYM is confining and contains strongly bound states.

Understanding Decoherence of the Boron Vacancy Center in Hexagonal Boron Nitride
Advanced Functional Materials, EarlyView.State‐of‐the‐art computations unravel the intricate decoherence dynamics of the boron vacancy center in hexagonal boron nitride across magnetic fields from 0 to 3 T. Five distinct regimes emerge, dominated by nuclear spin interactions, revealing optimal coherence times of 1–20 µs in the 180–350 mT range for isotopically pure samples.
