Decoherence and long-lived Schroedinger cats in BEC
Diego A. R. Dalvit, Jacek Dziarmaga, Wojciech H. Zurek
We consider quantum superposition states in Bose-Einstein condensates. A decoherence rate for the Schrödinger cat is calculated and shown to be a significant threat to this macrosc…
Scaling in dynamical Turing pattern formation: density of defects frozen into permanent patterns
Jacek Dziarmaga
We estimate density of defects frozen into a biological Turing pattern which was turned on at a finite rate. A self-locking of gene expression in individual cells, which makes the…
Decoherence in Bose-Einstein Condensates: towards Bigger and Better Schroedinger Cats
Diego A. R. Dalvit, Jacek Dziarmaga, Wojciech H. Zurek
We consider a quantum superposition of Bose-Einstein condensates in two immiscible internal states. A decoherence rate for the resulting Schroedinger cat is calculated and shown to…
