Advanced Functional Materials, EarlyView.Electroforming‐free TiN/SiOx/Cu/SiOx/TiN memristive devices exploit pancake‐like Cu nanoparticles embedded in a SiOx double layer to create a heterogeneous Schottky‐barrier landscape. Under bias, oxygen‐vacancy redistribution progressively lowers local barriers and recruits initially inactive Cu‐PC pathways into a parallel conduction ensemble, enabling

Perturbative and non-perturbative studies in low dimensional quantum field theory [PDF]
, 2007 A relevant perturbation of a conformal field theory (CFT) on the half-plane, by both a bulk and boundary operator, often leads to a massive theory with a particle description in terms of the bulk S-matrix and boundary reflection factor R.

Advanced Functional Materials, EarlyView.The intrinsic distortion‐rich lattice of HEPBA with GQD‐enabled microstrain engineering establishes a mechanistic route toward high‐performance alkaline hydrogen evolution reaction. HEPBA inherently feature heterogeneous local coordination environments arising from multimetal incorporation, while properly introducing GQD during coprecipitation ...

Aspects of model building in noncommutaive quantum field theories [PDF]
, 2004 We review quantum field theories on noncommutative Minkowski spaces (NCQFTs), concentrating on the mixing between ultra-violet and infra-red degrees of freedom in such theories.

Advanced Functional Materials, EarlyView.Programmable 2D magnetic clusterphenes are realized through a ligand‐mediated cluster‐assembly strategy. Direct linking of magnetic superatomic clusters enhances electron delocalization and symmetry breaking, enabling the concurrent strengthening of magnetic exchange interactions and spin–orbit coupling.

Idealization in Quantum Field Theory [PDF]
, 1998 This paper explores various functions of idealizations in quantum field theory. To this end it is important to first distinguish between different kinds of theories and models of or inspired by quantum field theory.

Deformations of Fermionic Quantum Field Theories and Integrable Models [PDF]
Letters in Mathematical Physics, 2012 Considering the model of a scalar massive Fermion, it is shown that by means of deformation techniques it is possible to obtain all integrable quantum field theoretic models on two-dimensional Minkowski space which have factorizing S-matrices corresponding to two-particle scattering functions S_2 satisfying S_2(0) = -1.

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 ...

Spontaneous Symmetry Breaking (II): Variations in Complex Models [PDF]
, 2002 This paper, part II of a two-part project, continues to explore the meaning of spontaneous symmetry breaking (SSB) by applying and expanding the general notion we obtained in part I to some more complex and, from the physics point of view, more important
