Temperature driven structural phase transition for trapped ions and its experimental detection
Temperature driven structural phase transition trapped ions experimental detection
font style='font-size:12px;'>
2010/10/21
A Wigner crystal formed with trapped ion can undergo structural phase transition, which is
determined only by the mechanical conditions on a classical level. Instead of this classical result, we show...
Finding structural anomalies in graphs by means of quantum walks
structural anomalies in graphs quantum walks
