Causality in Dense Matter
B. D. Keister (Carnegie Mellon)🇺🇸 · W. N. Polyzou (Iowa)🇺🇸
Abstract
The possibility of non-causal signal propagation is examined for various theories of dense matter. This investigation requires a discussion of definitions of causality, together with interpretations of spacetime position. Specific examples are used to illustrate the satisfaction or violation of causality in realistic calculations.
