Zeros of the Partition Function and Pseudospinodals in Long-Range Ising Models
Natali Gulbahce, Harvey Gould, W. Klein
The relation between the zeros of the partition function and spinodal critical points in Ising models with long-range interactions is investigated. We find the spinodal is associat…
Vortices in vibrated granular rods
Daniel L. Blair, T. Neicu, A. Kudrolli
We report the experimental observation of novel vortex patterns in vertically vibrated granular rods. Above a critical packing fraction, moving ordered domains of nearly vertical r…
Periodic orbit analysis of an elastodynamic resonator using shape deformation
T. Neicu, A. Kudrolli
We report the first definitive experimental observation of periodic orbits (POs) in the spectral properties of an elastodynamic system. The Fourier transform of the density of flex…
Swarming ring patterns in bacterial colonies exposed to ultraviolet radiation
Anna M. Delprato, Azadeh Samadani, A. Kudrolli +1
We report a novel morphological transition in a Bacillus subtilis colony initially growing under ambient conditions, after ultraviolet radiation exposure. The bacteria in the centr…
Magnetic properties of a new molecular-based spin-ladder system: (5IAP)2CuBr4*2H2O
C. P. Landee, M. M. Turnbull, C. Galeriu +2
We have synthesized and characterized a new spin-1/2 Heisenberg antiferromagnetic ladder: bis 5-iodo-2-aminopyridinium tetrabromocuprate(II) dihydrate. X-ray diffraction studies sh…
Segregation transitions in wet granular matter
Azadeh Samadani, A. Kudrolli
We report the effect of interstitial fluid on the extent of segregation by imaging the pile that results after bidisperse color-coded particles are poured into a silo. Segregation…
