Spin Glasses [PDF]

, 2016
Despite the extreme simplicity in their definition, spin glasses disclose a wide variety of non-trivial behaviors that are not yet fully understood. In this thesis we try to shed light on some of them, focusing on one hand on the search of phase transitions under perturbations of the Hamiltonian, and on the other hand on the zero-temperature properties

Roulette‐Inspired Physical Unclonable Functions: Stochastic yet Deterministic Multi‐Bit Patterning through the Solutal Marangoni Effect

Advanced Functional Materials, EarlyView.
Geometric multi‐bit patterning based on dynamic wetting and dewetting phenomena creates roulette‐like Physical Unclonable Function (PUF) labels with stochastic yet deterministic properties. This method leverages the solutal‐Marangoni effect for high randomness while achieving deterministic multinary patterns through polygonal confinement of binary ...

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 ...

Raman, FTIR, thermal and optical properties of TeO2-Nb2O5-B2O3-V2O5 quaternary glass system

Journal of Taibah University for Science, 2017
A series of quaternary glass systems with the composition 79TeO2-(20−x)Nb2O5-xB2O3-1V2O5 was prepared using the melt quench technique. Such studies as optical absorption, Raman, FTIR spectroscopy, EPR and DSC were carried out on the glass system.

Two-dimensional XY spin/gauge glasses on periodic and quasiperiodic lattices

, 1996
Via Monte Carlo studies of the frustrated XY or classical planar model we demonstrate the possibility of a finite (nonzero) temperature spin/gauge glass phase in two dimensions.

Multi‐Pathway Upconversion Emission in Symmetry‐Broken Nanocavities: Broadband Multiresonant Enhancement and Anti‐Correlated Interfacial Sensitivity

Advanced Functional Materials, EarlyView.
Symmetry‐broken plasmonic nanoantenna arrays achieve broadband multiresonant enhancement of second harmonic generation (SHG), third harmonic generation (THG), and upconversion photoluminescence (UCPL), under femtosecond laser excitation across the near‐infrared range (1000–1600 nm).

Dynamical Critical Phenomena in three-dimensional Heisenberg Spin Glasses

, 2002
Spin-glass (SG) and chiral-glass (CG) orderings in three dimensional (3D) Heisenberg spin glass with and without magnetic anisotropy are studied by using large-scale off-equilibrium Monte Carlo simulations.

Highly Efficient 3D‐Printed PVDF‐Based Triboelectric Nanogenerators Featuring Polymorphic Perovskite Nanofillers

Advanced Functional Materials, EarlyView.
This study demonstrates the use of a low‐cost 3D printing technique to prepare a large‐area PVDF‐FAPbI3 composite dielectric film for flexible TENG application. The δ→α phase transformation of the FAPbI3 nanofillers has significantly improved the β‐phase content, morphology, and dielectric properties of the PVDF film.
