Title:
Topological invariants, entanglement, and partial transpose in topological phases

Speaker:
Shinsei Ryu

Abstract:
I will discuss our recent proposal for the new definition of partial transpose for fermionic systems. As applications, i will discuss the construction of topological invariants and entanglement measure using the fermionic partial transpose. As target systems, I plan to discuss Majorana chains, and, if time allows, (2+1)d fermionic topological phases such as time-reversal symmetric topological insulators.
