Spin Bose Glass Phase in Bilayer Quantum Hall Systems at $\nu=2$

, 1998
We develop an effective spin theory to describe magnetic properties of the $\nu=2$ Quantum Hall bilayer systems. In the absence of disorder this theory gives quantitative agreement with the results of microscopic Hartree-Fock calculations, and for finite

Soft and Stiff 3D Microstructures by Step‐Growth Photopolymerization Using a Single Photoresin and Multi‐Photon Laser Printing

Advanced Functional Materials, EarlyView.
An additive and initiator‐free photoresin based on a prepolymer decorated with photoreactive step‐growth units as crosslinkers allows for the fabrication of 3D microstructures with strongly disparate mechanical properties ranging from stiff to soft. Abstract Manufacturing three‐dimensional (3D) microstructures with multi‐material properties via two ...

Room-temperature spin-glass behaviors and memory effects in Al-substituted Y3Fe5O12 epitaxial film grown by pulsed laser deposition

AIP Advances
This study explores the magnetic properties of a thin film of Al-substituted Y3Fe5O12 grown on Y3Al5O12 (111) substrates using pulsed laser deposition. Spin-glass behavior was observed near room temperature in the film, with a spin-freezing temperature ...

Critical interface: twisting spin glasses at $T_c$

, 2010
We consider identical copies of spin glasses in finite dimension coupled at the boundaries. This allows to identify the spin glass analogous of twisted boundary conditions in ferromagnetic system and leads to the definition of an interface free-energy ...

Evolution of genetic redundancy: the relevance of complexity in genotype–phenotype mapping

New Journal of Physics, 2014
Despite its ubiquity among organisms, genetic redundancy is presumed to reduce total population fitness and is therefore unlikely to evolve. This study evaluates an evolutionary model with high-dimensional genotype–phenotype mapping (GPM) by applying a ...

Understanding and Addressing the Performance Asymmetry Issue in Semitransparent Laminated Organic Photovoltaic Devices

Advanced Functional Materials, EarlyView.
This work addresses the challenge of current–voltage asymmetry in scalable laminated semitransparent organic photovoltaics (OPVs) for indoor applications. Vertical stratification of materials is shown to create an energy barrier, leading to performance differences under different illumination directions.
