Review of lattice supersymmetry and gauge-gravity duality [PDF]

International Journal of Modern Physics A, 2015
We review the status of recent investigations on validating the gauge-gravity duality conjecture through numerical simulations of strongly coupled maximally supersymmetric thermal gauge theories. In the simplest setting, the gauge-gravity duality connects systems of D0-branes and black hole geometries at finite temperature to maximally supersymmetric ...

Synergistic Solar Interfacial Evaporation and Photocatalysis Enabled by a Hierarchical Porous Hydrogel Reactor

Advanced Functional Materials, EarlyView.
A tree‐inspired hydrogel interfacial reactor couples solar evaporation with photocatalysis for simultaneous desalination and waste water treatment. The bilayer design achieves 2.14 kg·m−2·h−1 evaporation rate with 79% dye degradation under one sun, demonstrating that photothermal heating and evaporation induced pollutant enrichment create a self ...

Direct Channel Implantation of B and BF2 Ions for Functional Control of Oxygen Vacancies in Oxide Semiconductor Thin Film Transistors

Advanced Functional Materials, EarlyView.
Direct channel implantation of B and BF2 ions was employed to fabricate amorphous IGZO TFTs with improved electrical and stability properties. B and BF2 implantation modulate oxygen vacancies within the IGZO channel. The field‐effect mobility of ion‐implanted IGZO TFTs was enhanced as compared to pristine IGZO TFTs.

Mechanistic Control of C─H Bond Activation and C─C Coupling in Light‐Driven Methane Conversion to C2+ Products over Multifunctional Photocatalysts

Advanced Functional Materials, EarlyView.
Methane photocatalytic activation under mild conditions remains a formidable challenge in the synthesis of solar fuels. In this review, we emphasize the growing importance of multifunctional materials and hybrid systems within a unified mechanistic framework that integrates selective C─H bond activation, formation and control of intermediates, C─C ...

Impact of Disorder on Microscopic Superconducting and Normal‐State Responses in a Kagome Metal

Advanced Functional Materials, EarlyView.
Using depth‐resolved, field‐ and pressure‐dependent μSR$\umu{\rm SR}$ measurements, we show that disorder in Ta‐doped KV3Sb5 drives a crossover from nodal to nodeless superconductivity while strongly modifying the normal‐state magnetic response. Our results reveal that disorder affects superconductivity and magnetism in fundamentally different ways ...

Si‐Doped Nanocrystalline Diamond as Highly Sensitive Luminescence Thermometer for the Physiological Temperature Range

Advanced Functional Materials, EarlyView.
In this work, diamonds with negative charged silicon‐vacancy (SiV−) centers have been designed for use as thermometers in biomedical applications. Multiparametric analysis of the emission characteristics of the SiV− centers provides extraordinary sensitivity for temperature detection in the physiological temperature range.

Dualities in lattices of semigroup varieties

Semigroup Forum, 1990
The subvariety lattice of a variety \({\mathfrak V}\) of universal algebras is denoted by L(\({\mathfrak V})\). Varieties \({\mathfrak V}\) and \({\mathfrak V}'\) are said to be dual to one another if L(\({\mathfrak V})\) and L(\({\mathfrak V}')\) are dual lattices; \({\mathfrak V}\) is selfdual if L(\({\mathfrak V})\) is selfdual. Let \({\mathfrak X}\)
