Quasi-normal-mode signatures of periodicity and hyperuniformity
V. Romero-García, M. Martí-Sabaté, V. F. Dal Poggetto +2
Hyperuniform materials occupy an intermediate regime between periodic order and conventional disorder, characterized by a suppression of long-wavelength density fluctuations, commo…
Analytical approximations for multiple scattering in one-dimensional waveguides with small inclusions
Mario Lázaro, Richard Wiltshaw, Richard Vaughan Craster +1
We propose a new model to approximate the wave response of waveguides containing an arbitrary number of small inclusions. The theory is developed to consider any one-dimensional wa…
Validation of symmetry-induced high moment velocity and temperature scaling laws in a turbulent channel flow
Francisco Alcántara-Ávila, Luis Miguel García-Raffi, Sergio Hoyas +1
The symmetry-based turbulence theory has been used to derive new scaling laws for the streamwise velocity and temperature moments of arbitrary order. For this, it has been applied…
Hyperuniformity of quasiperiodic tilings generated by continued fractions
Mario Lázaro, Luis M. García-Raffi
Hyperuniformity is a property of certain heteroneous media in which density fluctuations in the long wavelength range decay to zero. In reciprocal space this behavior translates in…
