Stripe-tetragonal first-order phase transition in ultrathin magnetic films

We analyze the nature of the phase transition from a smectic stripe phase to a tetragonal phase predicted in analytic studies by Abanov et al. @Phys. Rev. B 51, 1023 ~1995!# and observed in experiments on ultrathin magnetic films by Vaterlaus et al. @Phys. Rev. Lett. 84, 2247 ~2000!#. At variance with existent numerical evidence, we show results of Monte Carlo simulations on a two-dimensional m...

Parametric vector solitons in tetragonal crystals.

We introduce novel types of spatial vector soliton that can be generated in anisotropic optical media, such as tetragonal crystals with third-order nonlinear susceptibility. We demonstrate that these vector solitons provide a nontrivial generalization to both conventional vector solitons of birefringent cubic media and parametric solitons supported by third-order cascaded nonlinearities.

Fabrication of Tetragonal Square Spiral Photonic Crystals

We present a simple, versatile technique for the fabrication of large, three-dimensional gap photonic crystals using glancing angle deposition (GLAD). A tetragonal lattice suitable for a large photonic band gap (PBG) can be synthesized by a regular array of square spiral structures grown from a simple, prepatterned substrate using physical vapor deposition and advanced substrate motion. Tetrago...

Structure of phonon focusing patterns in tetragonal crystals.

A set of critical conditions for the characteristic caustic points in the phonon focusing patterns in tetragonal crystals is formulated. A caustic line segment in the focusing pattern is generally associated with either a fold or a cusp on the wave surface. Most of the caustic lines are symmetrical with respect to the principal symmetry plane and can be characterized by the caustic points at th...

Oxygen ordering and the orthorhombic-to-tetragonal phase transition in YBa_{2}Cu_{3}O_{7-x}

In situ neutron powder diffraction measurements show that the orthorhombic-to-tetragonal phase transition in YBa2Cu307 —,which occurs near 700 C in a pure oxygen atmosphere, is an order-disorder transition in which the disordering of oxygen atoms into a normally vacant site destroys the one-dimensional Cu-0 chains present in the room-temperature orthorhombic structure. For both structures, the ...
