Title: Anyonic (or Symmetric) Tensor Network States
Speaker: Babatunde Ayeni (Maynooth University)
Abstract: The focus of my talk would be on a broad class of tensor networks (TN) with a generic type of quantum symmetry: anyonic symmetry. This class of tensor networks is called anyonic tensor networks. The progression of my talk would be: First, I will give a quick reminder of “ordinary” (or non-symmetric) tensor networks, particularly, matrix product states (MPS). Second, as a prelude to anyonic TN, I will show how to incorporate particle number [or U(1)] symmetry into TN giving a TN with a global particle number. Third, I will give an overview of the algebraic theory of anyons necessary for working with anyonic TN, and then I show the construction of anyonic tensors and associated tensor network states. Finally, I will discuss some simple models of many-body system of non-Abelian anyons and show some results.

#OTD in 2019 @mitchelloconnor unveiled a portrait of Dr Sheila Tinney here at DIAS. Dr Tinney was appointed the first ever female fellow at DIAS and later became a Research Associate at the Institute’s School of Theoretical Physics. Today also marks her birthday 🎂 #DIASdiscovers
Busy start to the week: An international team led by scientists from DIAS has discovered that large portions of the tectonic plate, or lithosphere, beneath Africa have disappeared over the past 200 million years More ➡️ dias.ie/2020/01/13/dia… @dias_geophysics #DIASdiscovers
An interesting story that includes one of the first ever DIAS staff members. #DIASdiscovers twitter.com/IrishTimesBook…
This week we took a look back at DIAS' significant achievements over the decade from 2010 to 2019. Learn More ➡️ dias.ie/2020/01/09/dia… #DIASdiscovers
DIAS is looking for an exceptional Senior Executive Officer to look after their Strategy Implementation and Impact. Interested? Learn More at dias.ie/2020/01/08/vac… Closes 31 January #DIASdiscovers #jobfairy
ICYMI: DIAS was awarded one of the first SALI Professorships in Physics on the 03 January. It is anticipated that recruitment for this position will begin in late Spring 2020. More ➡️ dias.ie/2020/01/06/dia… #DIASdiscovers #SALI #physics #jobfairy #gender #Balance
In 2017 Dr Eamon O'Gorman (then astronomer at the Dublin Institute for Advanced Studies) led an international team to create the image of Betelgeuse. Now one of the brightest stars in the sky has been dimming: dias.ie/betelgeusedims #DIASdiscovers #ALMA #telescope
