Efficient Magnetization Switching Driven by Orbital Torque in Light 3d Transition‐Metal Nitrides
Advanced Functional Materials, EarlyView.Efficient magnetization switching is demonstrated through orbital torque generated from light 3d transition‐metal nitride. Transition‐metal nitrides are established as effective sources of orbital angular momentum for current‐induced switching, highlighting their potential for low‐power next‐generation orbitronic devices beyond conventional heavy‐metal‐

Localization in quantum field theory
Reviews in PhysicsWe review the issue of localization in quantum field theory and detail the nonrelativistic limit. Three distinct localization schemes are examined: the Newton-Wigner, the algebraic quantum field theory, and the modal scheme. Among these, the algebraic quantum field theory provides a fundamental concept of localization, rooted in its axiomatic ...

Spin in Quantum Field Theory [PDF]
, 2007 I introduce spin in field theory by emphasizing the close connection between quantum field theory and quantum mechanics. First, I show that the spin-statistics connection can be derived in quantum mechanics without relativity or field theory. Then, I discuss path integrals for spin without using spinors.

Bell Correlations in Quantum Field Theory [PDF]
, 2011 Bell correlations are the hallmark of quantum non-locality, and a rich context for analysing them is provided by the algebraic approach to quantum field theory (AQFT): the basic idea is to associate with each bounded region O of Minkowski spacetime an ...

Advanced Functional Materials, EarlyView.Iontronic gating in a battery‐inspired device modulates the relative weight of surface‐associated and bulk‐like transport fingerprints in (Bi1‐xSbx)2Te3, resulting in phenomenological valve‐like transport behavior. The strongest WAL‐associated coherent transport signatures emerge near the transport‐defined carrier compensation regime at ultra‐low gate ...

Mechanical Strain Tunes Proton Chemistry at Oxide–Water Interfaces
Advanced Functional Materials, EarlyView.Strain dependence of interfacial water dissociation at the anatase TiO2${\rm TiO}_2$(101)–water interface. Left and middle panels show top‐view snapshots of the interfacial water layer at 0% and +4% biaxial strain; right panel shows the time evolution of the instantaneous dissociated fraction over the molecular dynamics trajectory for strains of 0 ...

Gravity as a Quantum Field Theory
Symmetry, 2023 Classical gravity is understood as the geometry of spacetime, and it seems very different from the other known interactions. In this review, I will instead stress the analogies: Like strong interactions, the low energy effective field theory of gravity is related to a nonlinearly realized symmetry, and like electroweak interactions, it is a gauge ...

Reeh-Schlieder defeats Newton-Wigner: On alternative localization schemes in relativistic quantum field theory [PDF]
, 2000 Many of the "counterintuitive" features of relativistic quantum field theory have their formal root in the Reeh-Schlieder theorem, which in particular entails that local operations applied to the vacuum state can produce any state of the entire

Advanced Functional Materials, EarlyView.Epitaxial strain drives oxygen‐octahedral reconfiguration in Sr2FeReO6 double‐perovskite thin films, inducing orbital‐selective reconstruction of Re 5d states through modified Fe–O–Re hybridization. This coupled lattice–orbital response enables magnetic easy‐axis reversal and a transition from metallic‐like to semiconducting‐like transport.

, 2019 I will give an overview of how the Batalin-Vilkovisky (BV) formalism can be incorporated into perturbative algebraic quantum field theory in full generality and I will discuss two examples: gauge theories and effective quantum gravity. In the latter case,
