Rotations and Lorentz transformations
, 2018 A computational approach to rotations and Lorentz transformation is presented. The discussion starts with the mathematical properties of the rotation and the proper orthochronous Lorentz groups.

Lorentz transformations and the wave equation [PDF]
, 2020 In this note we explicitly show how the Lorentz transformations can be derived by demanding form invariance of the d'Alembert operator in inertial reference ...

Advanced Science, EarlyView.A temperature‐driven magnetic anisotropy crossover is revealed in the Dirac kagome magnet Fe3Ge with a distorted kagome lattice. The transition from easy‐plane to easy‐axis magnetic anisotropy stabilizes robust Bloch‐type skyrmions over an exceptionally wide temperature window of 375–650 K.

From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits
Advanced Science, EarlyView.This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

Uniqueness of Simultaneity [PDF]
, 2000 I invesigate the question of existence and uniqueness of simultaneity structures in spacetimes whose automorphism group, Aut, is either the inhomogeneous proper orthochronous Galilei or Lorentz group.

High Upper Critical Field and Type II Superconductivity in Epitaxial Cubic W2N Thin Films
Advanced Science, EarlyView.Superconducting thin films of stoichiometric W2N demonstrate a high upper critical field (Hc2) of ∼ 8.5 T, uncommon among binary transition metal nitrides. This robust superconducting response under high magnetic fields highlights the technological relevance of W2N for superconducting applications, e.g., integrated quantum and cryogenic electronics ...

Off-shell unimodular N = 1, d = 4 supergravity
Journal of High Energy Physics, 2020 We formulate a unimodular N = 1, d = 4 supergravity theory off shell. We see that the infinitesimal Grassmann parameters defining the unimodular supergravity trans- formations are constrained and show that the conmutator of two infinitesinal unimodular ...

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 ...

Colossal Magnetic‐Field‐Induced Anomalous Hall Conductivity in a Kagome Antiferromagnet YMn6Sn6
Advanced Science, EarlyView.Magnetic‐field‐driven spin canting in the kagome antiferromagnet YMn6Sn6${\rm YMn}_6{\rm Sn}_6$ reshapes flat and Dirac bands near the Fermi level, redistributing Berry curvature and producing colossal anomalous Hall conductivity. The study reveals how magnetic configuration and clean‐limit skew scattering cooperate to amplify Hall transport, offering ...
