Space-time as a causal set.
We propose that space-time at the smallest scales is in reality a causal set: a locally finite set of elements endowed with a partial order corresponding to the macroscopic relation that defines pastExpand

Wide Solitons in an Ion-Beam-Plasma System.
Solitons are experimentally found in a double plasma device when an ion beam is present with beam velocity {ital v}{sub {ital b}} in the range 1{le}{ital v}{sub {ital b}}/{ital c}{sub {italExpand

Ferroelectric nematic liquid crystals: Realizability and molecular constraints.
There is no fundamental reason that fluids should not be ferroelectric. However, the only knownferroelectric fluids are chiral smectic-$C$ liquid crystals and related structures. We examine theExpand

Relaxation and the reentrant appearance of phases in a molecular monolayer.
The structure of monolayers of CH{sub 3}(CH{sub 2}){sub 22}COOH on water, along {similar to}21 {degree}C isotherms between 18 and 35 A {sup 2}/molecule, has been studied with glancing-angle x-rayExpand
