Lattice distortions in YBa2Cu3O7–delta thin films grown in situ by sequential ion beam sputtering [PDF]

, 1991
We have analyzed epitaxial, c-axis oriented YBa2Cu3O7–delta thin films grown in situ by sequential ion-beam sputtering on (100) SiTiO3 and (100) MgO substrates.

Unifying quantization for inhomogeneous integrable models

, 2005
Integrable inhomogeneous versions of the models like NLS, Toda chain, Ablowitz-Ladik model etc., though well known at the classical level, have never been investigated for their possible quantum extensions.

PAIRING IN INHOMOGENEOUS SUPERCONDUCTORS [PDF]

International Journal of Modern Physics B, 2000
Starting from a t-J model, we introduce inhomogenoeus terms to mimic stripes. We find that if the inhomogeneous terms break the SU(2) spin symmetry the binding between holes is tremendously enhanced in the thermodynamic limit. In any other model (including homogeneous models) the binind in the thermodynamic limit is small or neglible.

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

Advanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

Piezoresistive Monitoring of Carbon Nanomaterial‐Reinforced Epoxy Composites Under Cyclic and Fatigue Loading: A Review

Advanced Engineering Materials, EarlyView.
Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Multiscale Modeling of Silicon Carbide Cladding for Nuclear Applications: Thermal Performance Modeling

Energies
The complex multiscale and anisotropic nature of silicon carbide (SiC) ceramic matrix composite (CMC) makes it difficult to accurately model its performance in nuclear applications.

Die Behandlung des systematischen Fehlers bei Niederschlagsmessungen

Meteorologische Zeitschrift, 1992
Bei allen Arten von Niederschlagsmessungen mit konventionellen Meßgeräten treten geräteabhängig systematische Meßfehler auf, wobei im allgemeinen der aktuell gefallene Niederschlag unterschätzt wird.

Inhomogeneous Polyakov loop induced by inhomogeneous chiral condensates

Physics Letters B, 2015
We study the spatial inhomogeneity of the Polyakov loop induced by inhomogeneous chiral condensates. We formulate an effective model of gluons on the background fields of chiral condensates, and perform its lattice simulation.

Crystalline color superconductors

, 2014
Inhomogeneous superconductors and inhomogeneous superfluids appear in a variety of contexts including quark matter at extreme densities, fermionic systems of cold atoms, type-II cuprates, and organic superconductors. In the present review the focus is on

Inhomogeneous M-theory cosmologies [PDF]

Journal of Mathematical Physics, 2002
We study a class of inhomogeneous and anisotropic G2 string cosmological models. In the case of separable G2 models we show that the governing equations reduce to a system of ordinary differential equations. We focus on a class of separable G2 M-theory cosmological models, and study their qualitative behavior (a class of models with time-reversed ...
