New examples of Property (T) factors with trivial fundamental group and unique prime factorization
Sayan Das
In this paper we provide new examples of property (T) group factors with trivial fundamental group thereby providing more evidence towards Popa's conjecture on triviality of fundam…
Poisson boundaries of II factors
Sayan Das, Jesse Peterson
We introduce Poisson boundaries of II factors with respect to density operators that give the traces. The Poisson boundary is a von Neumann algebra that contains the II fac…
Examples of property (T) II factors with trivial fundamental group
Ionut Chifan, Sayan Das, Cyril Houdayer +1
In this article we provide the first examples of property (T) factors with trivial fundamental group, . Our examples arise as gro…
Floor- or ceiling-sliding for chemically active, gyrotactic, sedimenting Janus particles
Sayan Das, Zohreh Jalilvand, Mihail N. Popescu +3
Surface bound catalytic chemical reactions self-propel chemically active Janus particles. In the vicinity of boundaries, these particles exhibit rich behavior, such as the occurren…
