Query: Local Energy Landscape in a Simple Liquid   It is difficult to relate the properties of liquids and glasses directly to
their structure because of complexity in the structure which defies precise
definition. The potential energy landscape (PEL) approach is a very insightful
way to conceptualize the structure-property relationship in liquids and
glasses, particularly on the effect of temperature and history. However,
because of the highly multi-dimensional nature of the PEL it is hard to
determine, or even visualize, the actual details of the energy landscape. In
this article we introduce a modified concept of the local energy landscape
(LEL) which is limited in phase space, and demonstrate its usefulness using
molecular dynamics simulation on a simple liquid at high temperatures. The
local energy landscape is given as a function of the local coordination number,
the number of the nearest neighbor atoms. The excitations in the LEL
corresponds to the so-called beta-relaxation process. The LEL offers a simple
but useful starting point to discuss complex phenomena in liquids and glasses.
