The Evolution of Quantum Field Theory, From QED to Grand Unification

open access: yes, 2015
In the early 1970s, after a slow start, and lots of hurdles, Quantum Field Theory emerged as the superior doctrine for understanding the interactions between relativistic sub-atomic particles.

Quantum Antitrust – A Unified Exclusionary Abuse Theory

open access: yesIIC - International Review of Intellectual Property and Competition Law
AbstractNow that the judgments in Servizio Elettrico Nazionale and Unilever have made sense of previous case-law, a unified analytical framework can be predicated for all exclusionary abuses. It is made up of two limbs (artificiality/conduct deviating from competition on the merits and potential exclusionary effect/capability of foreclosing).

Prospects of Electric Field Control in Perpendicular Magnetic Tunnel Junctions and Emerging 2D Spintronics for Ultralow Energy Memory and Logic Devices

open access: yesAdvanced Functional Materials, EarlyView.
Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.

Graviton mass and entanglement islands in low spacetime dimensions

open access: yesSciPost Physics
It has been conjectured and proven that entanglement island is not consistent with long-range (massless) gravity in a large class of spacetimes, including typical asymptotically anti-de Sitter spacetimes, in high spacetime dimensions.

Controlled Aggregation of Pyrene‐Based Supramolecular Nanostructures for Light‐Driven Switchable H2 or H2O2 Production

open access: yesAdvanced Functional Materials, EarlyView.
This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.

Unifying Two Notions of Nonlocality in Quantum Theory

open access: yes, 2020
Ensembles containing orthogonal product states are found to be indistinguishable under local operations and classical communication (LOCC), thereby showing irreversibility in the preparation and distinguishing processes, which is commonly known as nonlocality without entanglement.

Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors

open access: yesAdvanced Functional Materials, EarlyView.
This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).

A New Space-Time Theory Unravels the Origins of Classical Mechanics for the Dirac Equation

open access: yesQuantum Reports
The Feynman path integral plays a central role in quantum mechanics, linking classical action to propagators and relating quantum electrodynamics (QED) to Feynman diagrams.

Gauge (non-)invariant Green functions of Dirac fermions coupled to gauge fields

open access: yes, 2002
We develop a unified approach to both infrared and ultraviolet asymptotics of the fermion Green functions in the condensed matter systems that allow for an effective description in the framework of the Quantum Electrodynamics. By applying a path integral
