Ferroelastic phase in SrBi2Ta2O9 and study of the ferroelectric phase-transition dynamics
(AIP Publishing, 2002-08)
Polarized microscope observation of ferroelastic domains in a SrBi2Ta2O9 (SBT) single crystal reveals the presence of domains up to T(c1)similar or equal to770 K, which supports the ferroelasticity and Amam symmetry of the ...
Random walks with imperfect trapping in the decoupled-ring approximation
Mass, entropy, and holography in asymptotically de Sitter spaces
(American Physical Society, 2002-06-15)
We propose a novel prescription for computing the boundary stress tensor and charges of asymptotically de Sitter (dS) spacetimes from data at early or late time infinity. If there is a holographic dual to dS spaces, defined ...
Short distance versus long distance physics: The classical limit of the minimal length uncertainty relation
(American Physical Soc, 2002-07-15)
Stationary correlations for a far-from-equilibrium spin chain
(American Physical Society, 2002-10)
A kinetic one-dimensional Ising model on a ring evolves according to a generalization of Glauber rates, such that spins at even (odd) lattice sites experience a temperature T(e) (T(o)). Detailed balance is violated so that ...
Effect of the minimal length uncertainty relation on the density of states and the cosmological constant problem
(American Physical Soc, 2002-06-15)
Universality classes in the anisotropic Kardar-Parisi-Zhang model
(E D P Sciences, 2002-09-01)
Effects of violating detailed balance on critical dynamics
(American Physical Society, 2002-01-28)
We present an overview of the effects of detailed-balance violating perturbations on the universal static and dynamic scaling behavior near a critical point. It is demonstrated that the standard critical dynamics universality ...
Direct evidence for singlet-triplet exciton annihilation in pi-conjugated polymers
(American Physical Society, 2002-12-06)
A blend of two conjugated polymers with different optical band gaps and different triplet exciton (TE) magnetic resonance features was studied by means of photoinduced absorption (PA) and photoluminescence detected magnetic ...
