Quantum Phase Transitions in Graphene Coupled to a Twisted WSe2 Moiré Ferroelectricity

Advanced Materials, EarlyView.
Moiré ferroelectricity in twisted WSe2 (t‐WSe2) breaks graphene's sublattice symmetry, inducing a room‐temperature metal‐insulator transition. Coupling graphene with ferroelectric domains of t‐WSe2 creates local Dirac points and metallic phases with Fermi‐liquid and non‐Fermi‐liquid behavior.

Filters in topology optimization

International Journal for Numerical Methods in Engineering, 2001
AbstractIn this article, a modified (‘filtered’) version of the minimum compliance topology optimization problem is studied. The direct dependence of the material properties on its pointwise density is replaced by a regularization of the density field by the mean of a convolution operator.

Topology optimized microbioreactors

Biotechnology and Bioengineering, 2010
AbstractThis article presents the fusion of two hitherto unrelated fields—microbioreactors and topology optimization. The basis for this study is a rectangular microbioreactor with homogeneously distributed immobilized brewers yeast cells (Saccharomyces cerevisiae) that produce a recombinant protein.

Metric-topological–evolutionary optimization

Inverse Problems in Science and Engineering, 2011
This article shows a novel approach for optimization and inverse problems based on evolutionary computation with the aim to satisfy two opposite requirements: exploration and convergence. The proposed approach is particularly suitable for parallel computing and it gives its best both for multimodal problems and for problems in which bad initializations

Multidiscipline topology optimization

Computers & Structures, 1997
Abstract Topology optimization is used for determining the best layout of structural components to achieve predetermined performance goals. The density method which uses material density of each finite element as the design variable, is employed. Unlike the most common approach which uses the optimality criteria methods, the topology design problem ...
