Characterisations of Lorentz transformations
, 1985 A.D. Alexandrov in 1953, and E.C. Zeeman in 1964 independently published papers proving that the assumption of linearity is unnecessary for characterising Lorentz Transformations.

Energy Science &Engineering, EarlyView.The novelty of the current study is that the unsteady MHD Cross nanofluid model is, for the first time, coupled with the melting heat transfer at the stagnation point over a horizontally extended cylinder in a Darcy–Forchheimer porous medium. This work connects complex rheological behaviors and phase‐change phenomena in a unique way, with the only ...

Artificial structures for human‐machine interfaces with closed‐loop interaction
FlexMat, EarlyView.Artificial structures bridge sensing and feedback in closed‐loop human‐machine interfaces by providing geometry‐enabled mechanical and functional programmability. This review maps the role of artificial structures in diverse sensing modalities and feedback strategies, and illustrates their integration into closed‐loop interaction systems, highlighting ...

Resonant States Reveal Strong Light–Matter Coupling in Nanophotonic Cavities
Laser &Photonics Reviews, EarlyView.Photonic resonant states reveal characteristics of coupled light–matter systems that would otherwise be hidden by damping. Their trajectories (when tuning the optical resonance) undergo a qualitative change at the onset of strong coupling: They start swapping positions.

On approximate Lorentz transformations of the first and second orders
, 1975 Approximate Lorentz transformations of the first ((c-2)0) (Galilean transformations) and second (c-2) (x = (x' + βct') (1 + β2/2), t =t' (1 + β2/2) + βx'/C) orders are considered.

Controlling the Center of Mass Motion of Levitated Particles Using Structured Wavefronts
Laser &Photonics Reviews, EarlyView.Optically levitated particles have great potential for quantum‐enhanced sensing. Precise control of the trapping beam is crucial to improve the stability and confinement of these systems. Here, we study how structured wavefronts can be used to control the center‐of‐mass motion of levitated particles, enhancing trap stiffness and enabling stable ...

Laser &Photonics Reviews, EarlyView.Room‐temperature lower‐polariton‐like lasing is realized in an InGaN/GaN thin‐film ridge cavity with lateral distributed Bragg reflectors. Near‐field optical microscopy distinguishes the transverse side‐DBR‐confined mode from a longitudinal photon‐like mode, while simulations reproduce their spatial profiles.

The spin-statistics connection: Some pedagogical remarks in response to Neuenschwander's question
Electronic Journal of Differential Equations, 2000 Q: Is there a simple proof of the Spin-Statistics Theorem? A: Not if all that is assumed is invariance under the Euclidean Group. When this hypothesis is supplemented by invariance under restricted Lorentz transformations, the key move is to disregard ...

Noise Suppression via Gain‐Dispersion‐Managed Nonlinear Amplification in a High‐Power Er‐Fiber Laser
Laser &Photonics Reviews, EarlyView.Gain‐dispersion‐managed nonlinear pre‐amplification simultaneously suppresses phase and intensity noise, enabling scalable high‐power fiber amplification. The system delivers 102.3 W linearly polarized pulses with 1.19 µJ energy at 85.69 MHz and compresses them to 380 fs. Near‐linear power scaling without evident saturation highlights a practical route
