Photon band structures: The plane-wave method.
  • Leung, Liu
  • Physics
    Physical review. B, Condensed matter
  • 15 May 1990
TLDR
The optimal volume- filling fraction of spheres for the creation of a gap in the photon density of states is found to vary substantially with the relative dielectric constant r, and this gap persists for r as small as 3.
Influence of Neonatal Rearing Conditions on Stress‐Induced Adrenocorticotropin Responses and Norepinepherine Release in the Hypothalamic Paraventricular Nucleus
TLDR
Early life events may serve to influence the differentiation of noradrenergic neurones and thus alter HPA responses stress in adulthood, as examined in adult animals exposed to daily periods of handling or maternal separation over the first 2 weeks of life.
Electronic structure of the semimetals Bi and Sb.
  • Liu, Allen
  • Physics, Materials Science
    Physical review. B, Condensed matter
  • 15 July 1995
TLDR
A third-neighbor tight-binding model, with spin-orbit coupling included, is developed, to treat the electronic properties of Bi and Sb quantitatively and should be useful for calculations of the electronic property of proposed semimetal-semiconductor systems, including superlattices and resonant-tunneling devices.
Shear-Induced Gelation and Fracture in Micellar Solutions.
  • Liu, Pine
  • Physics
    Physical review letters
  • 2 September 1996
TLDR
Measurements indicate a correspondence between the shear-induced structural changes the authors measure and a number of well-documented but puzzling observations in the rheological response of the system, which has observed sheer-induced gelation, fracture, and the formation of intricate cyclic patterns caused by an elastic instability.
Full vector wave calculation of photonic band structures in face-centered-cubic dielectric media.
  • Leung, Liu
  • Physics
    Physical review letters
  • 19 November 1990
TLDR
The plane wave method is used to solve the exact Maxwell's equations without the use of the scalar approximation to calculate the photonic band structure of a face-centered cubic lattice of spheres in a uniform host medium.
Relaxation at the angle of repose.
  • Jaeger, Liu, Nagel
  • Geology, Physics
    Physical review letters
  • 2 January 1989
TLDR
In contradiction to recent models by Bak, Tang, and Wiesenfeld for the dynamics of granular systems, the distribution of avalanches is investigated and it is found that the slope of a sandpile decays as $log(t)$ when vibrations are introduced.
Fractal model for the ac response of a rough interface.
  • Liu
  • Physics
    Physical review letters
  • 29 July 1985
TLDR
A fractal model is proposed for a rough interface between two materials of very different conductivities, e.g., an electrode and an electrolyte, which provides insight into the conducting properties of the percolating cluster and the source of the 1/f noise in electronic components.
Onset of superconductivity in the two-dimensional limit.
The onset of superconductivity in homogeneous ultrathin films is found to occur when their normal-state sheet resistance falls below a value close to h/4e/sup 2/, the quantum resistance for pairs.
Boundary condition for fluid flow: Curved or rough surfaces.
TLDR
The curvature of the boundary is shown to alter the fluid's slip length, which may even become negative as a result and the microscopically calculated and macroscopically measured slip lengths can be quite different.
