Waves induced by heterogeneity in oscillatory media
New Journal of Physics, 2020 Various behaviours of nonlinear wave propagation and competition have been discussed and investigated extensively and meticulously, especially when the media are homogeneous. However, corresponding studies in heterogeneous media are much scarcer. In this

Advanced Science, Volume 13, Issue 44, 7 August 2026.Defect‐configurational origins of the asymmetric apparent electrostrain are revealed in different piezoelectric ceramics via atomic‐scale visualization of defect configurations. Migration of oxygen vacancies leads to the electrobending effect in N2‐sintered BaTiO3, while defect dipoles in Ba0.99TiO2.99 generate true asymmetric electrostrain without ...

Scan‐Path‐ and Initial‐State‐Dependent Superdomain Switching in (111)‐Oriented PZT
Advanced Electronic Materials, Volume 12, Issue 16, 24 August 2026.Scan trajectory and initial superdomain topology govern polarization switching in (111)‐oriented PZT. Automated AFM writing, pulsing experiments, and interferometric 3D‐PFM show that raster scans reproducibly stabilize ordered Type‐I stripe superdomains with constrained variant selection, whereas spiral trajectories generate frustrated mixed‐variant ...

Annalen der Physik, Volume 538, Issue 8, August 2026.ABSTRACT The unification of quantum mechanics and general relativity remains a central problem in fundamental physics. Here, we study the gravitomagnetic Aharonov–Bohm (AB) effect for Cooper pairs in Kerr spacetime. Frame‐dragging by a rotating black hole (BH) generates an effective vector potential through the off‐diagonal metric term gtϕ$g_{t\phi }$,

Logarithmic deformations of the rational superpotential/Landau-Ginzburg construction of solutions of the WDVV equations [PDF]
, 2008 The superpotential in the Landau-Ginzburg construction of solutions to the Witten-Dijkgraaf-Verlinde-Verlinde (or WDVV) equations is modified to include logarithmic terms.

On the Analyticity for the Generalized Quadratic Derivative Complex Ginzburg-Landau Equation
Abstract and Applied Analysis, 2014 We study the analytic property of the (generalized) quadratic derivative Ginzburg-Landau equation (1/2⩽α⩽1) in any spatial dimension n⩾1 with rough initial data.

Decoding Superconductivity in La3Ni2O7−δ Thin Films via Ozone‐Driven Structure and Oxidation Tuning
Small Structures, Volume 7, Issue 8, August 2026.We demonstrate that superconductivity in La3Ni2O7‐δ thin films correlate with the LNO‐2222 polytype, which must extend coherently across the layer. Conversely, the LNO‐1313 phase disrupts superconductivity, as confirmed by recent studies. Our work highlights the need to stabilize the 2222 phase through optimized growth to achieve robust and ...

Nonlinear Magnetoconvection in a Sparsely Packed Porous Medium
International Journal of Geophysics, 2011 Linear and weakly nonlinear properties of magnetoconvection in a sparsely packed porous medium are investigated. We have obtained the values of Takens-Bogdanov bifurcation points and codimension two bifurcation points by plotting graphs of neutral curves
