Nonexistence of smooth solutions for a full viscous isentropic liquid crystal system in three dimensions

Tudor Ratiu

We prove that the smooth solutions to the Cauchy problem for a full isentropic three-dimensional liquid crystal nematodynamic equations with conserved mass, linear momentum, and dissipating total energy, can lose classical smoothness within a finite time. ...

Room Helps: Acoustic Localization With Finite Elements

Martin Vetterli, Ivan Dokmanic

Acoustic source localization often relies on the free-space/far-field model. Recent work exploiting spatio-temporal sparsity promises to go beyond these scenarios, however, it requires the knowledge of the transfer functions from each possible source locat ...

Phase diagram of the fully frustrated transverse-field Ising model on the honeycomb lattice

Frédéric Mila, Jean-David Picon, Tommaso Coletta

Motivated by the current interest in the quantum dimer model on the triangular lattice, we investigate the phase diagram of the closely related fully frustrated transverse-field Ising model on the honeycomb lattice using classical and semiclassical approxi ...

Adaptive finite elements with large aspect ratio for electroosmotic and pressure-driven microflows

Martinus Gijs, Marco Picasso, Virabouth Prachittham

A space–time adaptive method is presented for the numerical simulation of mass transport in electroosmotic and pressure-driven microflows in two space dimensions. The method uses finite elements with large aspect ratio, which allows the electroosmotic flow ...

Wiley-Blackwell2010

In this text, we introduce the basic concepts for the numerical modelling of partial differential equations. We consider the classical elliptic, parabolic and hyperbolic linear equations, but also the diffusion, transport, and Navier-Stokes equations, as w ...

, ,

A numerical approach, named TransChlor, is proposed to simulate transport phenomena of various substances in concrete. This approach is a theoretical model based on finite elements and finite differences methods. The model consists of coupled nonlinear par ...

Long-range order in the Bose-Einstein condensation of polaritons

Vincenzo Savona, Davide Sarchi

We adopt a kinetic theory of polariton nonequilibrium Bose-Einstein condensation to describe the formation of off-diagonal long-range order. The theory accounts properly for the dominant role of quantum fluctuations in the condensate. In realistic situatio ...

Stability of spherically symmetric wave maps

Joachim Krieger

We study Wave Maps from R2+1 to the hyperbolic plane H-2 with smooth compactly supported initial data which are close to smooth spherically symmetric initial data with respect to some H1+mu, mu > 0. We show that such Wave Maps don't develop singularities i ...

2006

Self-stabilizing systems can automatically recover from arbitrary state perturbations in finite time. They are therefore well-suited for dynamic, failure prone environments. Spanning-tree construction in distributed systems is a fundamental task which form ...

2003

Diffractive optical elements comprising sub-wavelength aperiodic surface reliefs of finite length require the use of rigorous solvers for Maxwell's equations. We present a detailed analysis of Focusing Grating Couplers (FGC's) using a recently introduced 2 ...
