Topological phase transitions in glassy quantum matter
Isac Sahlberg, Alex Westström, Kim Pöyhönen, Teemu Ojanen
Abstract
In this work the authors develop a theory of topological phase transition in amorphous quantum systems. They uncover evidence that density-driven transition is completely new type of topological phase transition which exhibits striking departures from the well-established quantum Hall- type transitions.
