DESCRIPTION:Title: Nonreciprocal Wave Propagation in Periodic Elastic Media
 \n\nAbstract:\n\nWhen a wave travels in a material from one point to anoth
 er\, it propagates in compliance with the principle of reciprocity: if the
  locations of the source and receiver are interchanged\, the recorded sign
 al remains unchanged. This symmetry property of wave propagation has serve
 d as a powerful modeling and experimental tool in vibroacoustics for over 
 a century. In a recent change of perspective\, reciprocity is regarded as 
 a hindrance for creation of intrinsically biased waveguides and materials\
 , such as one-way mirrors and diodes for elastic waves. Recent experiments
  have shown the feasibility of creating such devices in the context of lat
 tice materials and mechanical metamaterials. In this light\, we review the
  scenarios for realizing nonreciprocal dynamics in periodic elastic media\
 , with a focus on strategies that utilize nonlinearity for achieving this.
