Matrix Representation of Planar Lorentz Transformations in Extended (2 + 2)-Dimensional Spacetime
Advances in Mathematical PhysicsA matrix formulation of Lorentz transformations restricted to planar motion is developed within an extended 2+2-dimensional spacetime framework. Focusing on inertial frames in relative motion confined to the XY-plane, the analysis begins with radial ...

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.

Giant Anisotropy and High Second‐Order Nonlinearity of 3R‐MoS2 for Multifunctional Photonics
Advanced Materials, EarlyView.Graphical abstract highlights, 3R‐polytype of MoS2 (3R‐MoS2) as a multifunctional photonic platform enabled by giant optical anisotropy and optical nonlinearities, demonstrating subdiffractional waveguiding, giant second‐harmonic (SH) generation, and high‐performance reflective polarization control.

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.

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.

Advanced Materials, EarlyView.We identify strong anisotropy in the upper critical field and magnetoresistance in the kagome superconductor LaRu3Si2, revealing pronounced electronic anisotropy. Uniaxial stress enhances magnetoresistance and Tc, with a positive correlation suggesting an electronic pairing mechanism.

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.

Far‐Infrared Hyperbolic Phonon–Polaritons in Zirconium Disulfide
Advanced Materials, EarlyView.An unpatterned ZrS2${\rm ZrS}_2$ flake, coupled to far‐field infrared light by metal nanoribbons, reveals hyperbolic phonon polaritons with multiple higher‐order branches and effective refractive indices up to 223. This resonator‐assisted approach establishes ZrS2${\rm ZrS}_2$ as a compact van der Waals platform for deeply subwavelength far‐infrared ...

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

Advanced Materials, EarlyView.Hydration‐induced symmetry breaking transforms layered LiInP2S6${\rm LiInP}_2{\rm S}_6$ from a nonpolar to a chiral‐polar phase, producing a giant enhancement of non‐resonant second‐harmonic generation. The reversible tuning of polar order through molecular intercalation establishes a strategy for dynamically controlling nonlinear optical ...
