A lot of traveling

I’ve been traveling a lot lately, you might have noticed how I have been unable to update the blog frequently. Here is a quick update of where science has taken me.

November

Dresden – There I visited the group of Wanter Strunz. They are experts in open quantum systems and quantum optics, and we had much to discuss about open systems with initial system-environment correlations. Dresden has some stunning architecture.

Ulm – Susana Huelga invited me to the beautiful city of Ulm. I’m friends with many people in her group, and this was a great opportunity to catch up, and discuss some new research ideas.

December

Hong Kong – GuanHua Chen invited to Hong Kong University where we worked together on open quantum systems, master equations and quantum transport. Also, during these days, I was able to participate in the CECAM Workshop on Simulating and Modeling Emerging Electronics. This was a fantastic conference where I learned about the challenges of nano-electronics. This was a fun and intense visit. Fun, because Hong Kong is a very fun city to explore, and has amazing food. Intense, because the conference was very productive, with a lot of ideas flying around.

Non-Markovian Open Quantum Systems: System-Environment Correlations in Dynamical Maps

My paper on Non-Markovian Open Quantum systems has been published in the Special Issue of International Journal of Quantum Information (IJQI):

Non-Markovian Open Quantum Systems: System-Environment Correlations in Dynamical Maps

We construct a non-Markovian dynamical map that accounts for systems correlated to the environment. We refer to it as a canonical dynamical map, which forms an evolution family. The relationship between inverse maps and correlations with the environment is established. The mathematical properties of complete positivity is related to classical correlations, according to quantum discord, between the system and the environment. A generalized non-Markovian master equation is derived from the canonical dynamical map.

This paper is an updated version of my 2008 preprint.
