Advanced Science, EarlyView.Interlayer sliding in the RuO2Zn2F2 bilayer induces ferroelectricity and enables reversible valley polarization switching. The electric dipole and valley‐resolved band edges are intimately coupled, revealing sliding ferroelectricity as a powerful mechanism for electrical control of valley degrees of freedom in 2D materials.

On integrable conservation laws [PDF]
, 2014 We study normal forms of scalar integrable dispersive (non necessarily Hamiltonian) conservation laws via the Dubrovin-Zhang perturbative scheme. Our computations support the conjecture that such normal forms are parametrised by infinitely many arbitrary

Advanced Science, EarlyView.Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

Numerical analysis of structure preserving Nyström methods for Hamiltonian systems [PDF]
, 2005 Energy conservation is an essential property of conservative mechanical systems that should be carried over to the numerical solution. Betsch and Steinmann proposed recently perturbed potentials to achieve energy conservation in the time integration of N-

Sliding Ferroelectricity Driven Spin‐Layertronics in Altermagnetic Multilayers
Advanced Science, EarlyView.Integrating sliding ferroelectricity with altermagnetism enables nonvolatile electrical control of spin and layer degrees of freedom. In bilayer CuF2, interlayer translation reverses layer‐locked spin‐split bands, establishing a multifunctional “spin‐layertronic” platform.

Complex Hamiltonian equations and Hamiltonian energy
, 2006 In the framework of Kaehlerian manifolds, we obtain complex Hamiltonian equations on momentum phase space T*M. Also we conclude complex Hamiltonian equations via the Legendre transformation. Then, definiting complex Routhian function similar to real analogue, we calculate Hamiltonian energy function of the system associated to complex Routhian function.
