Extended Linear and Nonlinear Lorentz Transformations and Superluminality
Advances in High Energy Physics, 2013 Two broad scenarios for extended linear Lorentz transformations (ELTs) are modeled in Section 2 for mixing subluminal and superluminal sectors resulting in standard or deformed energy-momentum dispersions.

Subleading BMS charges and the Lorentz group
Journal of High Energy Physics, 2022 The extended BMS group includes supertranslation, dual supertranslation and Lorentz transformations. The generators of these symmetries can be classified according to their parity into “electric” and “magnetic” types.

Energy as Frequency, Relative Velocity and Lorentz Transformations [PDF]
, 2023 In quantum mechanics, energy is associated with frequency for both a particle with rest mass and a photon. In the case of the photon, we try to show that this result follows from special relativity (Lorentz transformation) which in the photon case gives ...

Tailoring Phonon‐Driven Responses in α‐MoO3 through Isotopic Enrichment
Advanced Materials, EarlyView.ABSTRACT The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material, α‐MoO3, an orthorhombic crystal boasting three distinct phonon dispersions, provides three polaritonic dispersions of hyperbolic phonon polaritons (HPhPs) across the ...

Interactions in the IKKT matrix model on covariant quantum spacetime
Nuclear Physics BWe study the interactions of the higher-spin gauge theory arising from the IKKT matrix model on a covariant quantum FLRW quantum space-time MJ1,3, denoted as HS-IKKT.

Advanced Materials, EarlyView.Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

Gauged double field theory, current algebras and heterotic sigma models
Journal of High Energy Physics, 2023 We study the O(D, D + n) generalized metric and the gauge symmetries in the gauged double field theory (DFT) in view of current algebras and sigma models.

Advanced Materials Interfaces, EarlyView.ABSTRACT This study demonstrates that weak magnetic fields (16–40 mT) increase the efficiency of the hydrogen evolution reaction (HER) in electrocatalysts based on non‐fullerene acceptor (NFA) derivatives IT‐4Cl and Y6. Electrochemical measurements reveal that the application of the magnetic field reduces the onset potential and increases the current ...

Consistent interactions of Curtright fields
Journal of High Energy Physics, 2020 Consistent self-interactions of Curtright fields (Lorentz tensors with (2, 1) Young diagram index symmetry) are constructed in dimensions 5 and 7. Most of them modify the gauge transformations of the free theory but the commutator algebra of the deformed

Properties of Different Types of Lorentz Transformations
, 2020 It is obvious that Lorentz transformation is the starting point of Relativ istic mechanics. There are different types of Lorentz transformat ions such as Special, Most general, Mixed nu mber, Geo metric p roduct, and Quaternion Lo rentz transformations ...
