A Lorentz-equivariant transformer for all of the LHC

SciPost Physics
We show that the Lorentz-Equivariant Geometric Algebra Transformer (L-GATr) yields state-of-the-art performance for a wide range of machine learning tasks at the Large Hadron Collider.

Quantum work for deriving and explaining the Lorentz transformations [PDF]

AIP Advances
The Lorentz transformations of mass and time are derived and explained within the framework of quantum-process thermodynamics. To this end, various notions of quantum work are employed to describe the behavior of an accelerated particle, such as an ...

Majorana spinors and extended Lorentz symmetry in four-dimensional theory

, 2007
An extended local Lorentz symmetry in four-dimensional (4D) theory is considered. A source of this symmetry is a group of general linear transformations of four-component Majorana spinors GL(4,M) which is isomorphic to GL(4,R) and is the covering of an ...

Defect Properties and Band Energetics of Atomic Layer Deposited MoOX on Crystalline Si

Advanced Materials Interfaces, EarlyView.
Atomic layer deposited MoOx thin films grown using oxygen plasma and ozone co‐reactants exhibit tunable defect densities and band energetics. Optical and X#x02010;ray photoelectron spectroscopies reveal oxygen#x02010;vacancy#x02010;induced defect and polaron states and their impact on band alignment at the c#x02010;Si/MoOx interface, providing insight ...

Room Temperature Synthesis and Photopatterning of Mesoporous Titanium Dioxide Thin Films

Advanced Materials Technologies, EarlyView.
A nanofabrication strategy combining deep‐UV photolithography with block copolymer self‐assembly enables direct patterning and mineralization of mesoporous TiO2 thin films at room temperature. Photocatalytic titanium oxo‐clusters promote polymer degradation under UV irradiation, enabling multiscale control over porosity, film thickness, and lateral ...

The Poincaré and BMS flux-balance laws with application to binary systems

Journal of High Energy Physics, 2020
Asymptotically flat spacetimes admit both supertranslations and Lorentz transformations as asymptotic symmetries. Furthermore, they admit super-Lorentz transformations, namely superrotations and superboosts, as outer symmetries associated with super ...
