Segmented flows consist of two immiscible fluids which travel along a channel in a segmented arrangement due to an imposed pressure difference.
When interactions between magnetic degrees of freedom are incompatible with the underlying crystal lattice, exotic phenomena such as spin ice or spin liquid phases can result.
The idea that some systems could have a thermodynamically-large number of accessible ground states was presaged in the work of Pauling on ice.
A comment on "Nonlinear Excitations on a Quantum Ferromagnetic Chain" by R. Balakrishnan and A. R. Bishop, Phys. Rev. Lett. 55, 537 (1985).
Three classes of monosubstituted carbenes (aryl-, vinyl-, carbonyl- ) and one class of disubstituted carbenes (dicarbonyl-), all of them ground state triplets, can exist in more than one rotameric
In a number of experiments, 1 2 3 propagation of magnetoelastic waves has been observed in discs and rods of y t t r i u m iron garnet.
The propagation of a Gaussian beam and its transformation through a lens has been well treated in previous literature.
The use of plastic coatings in optical-fiber technology is multifaceted.
Geometric frustration is a concept underlying many mysterious materials phenomena.
In the spring semester of 1990, the three of us organized and ran a new course at Princeton, called "Geometry and the Imagination" after the famous book by Hilbert and Cohn-Vosssen.
