Effect of triple interaction on energy delocalization in the strongly disordered system of interacting two-level defects

Understand

We accurately treat the effect of the double and triple interactions of two-level systems (TLS) in glasses onto the energy delocalization due to the long-range interaction of TLS.

• Although this work qualitatively reproduces the estimates of our previous work we believe that it is important because in this paper the estimates are done with quantitative accuracy.
• This work can serve as the important step towards the development of quantitative theory of many-body delocalization due to the long-range interaction.
• Our study is compared with the recent work by Bodea et al claiming that the interaction of TLS triples leads to the energy delocalization.
