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…
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…
A holographic superconductor forced through interactions
Pallab Basu, Jyotirmoy Bhattacharya, Sayan Kumar Das
We propose a novel mechanism to achieve superconductivity at zero chemical potential, within the holographic framework. Extending previous construction of the holographic supercond…
Rigidity results for von Neumann algebras arising from mixing extensions of profinite actions of groups on probability spaces
Ionut Chifan, Sayan Das
Motivated by Popa's seminal work \cite{Po04}, in this paper, we provide a fairly large class of examples of group actions satisfying the extended Neshveyev-St…
Electric field- induced Pinch-off of a migrating compound droplet in confined micro channel
Somnath Santra, Sayan Das, Suman Chakraborty
The present study looks into the pinch-off dynamics of a compound droplet, which is suspended in another fluid in a parallel plate microchannel. The droplet is subjected to a trans…
