Hello mathstodon! 👋
We are a computational #quantum #physics group at the Freie Universität Berlin and the Dahlem Center for Complex Quantum Systems.
Our research interests are in the #QuantumControl of atoms, molecules and condensed matter systems with an #AMO like structure as well as #QuantumInformation processing.
We are using both #CoherentControl concepts and #OptimalControl theory, applying them to isolated as well as open quantum systems.
The development of optimal control methods is a major part of our work. A current emphasis is on control methods for open quantum systems.

We collaborate with research groups all over Europe (France, Spain, Switzerland), Israel and the US.

Thanks for having us, we are looking forward to sharing and discussing research updates!

Ricki Rosendahl

Born in Germany • Birth year 1975 · Studied Maths at University of Hamburg • Highest Degree PhD in Optimal Control • Lives in Hamburg, Germany • Occupation Senior Business Consultant I am sitting on the train. The ICE drives from Cologne to Hamburg. In this dark evening. My head is spinning after four days of learning about actuarial subjects in a seminar. I use my time to reflect. Thinking a little about the past, a little more about the future and a lot about this moment right now. I am happy. Grateful. I like being here and in this moment. I am thankful for my talent for mathematics my mom and dad gave me. Thankful for meeting other people in my life, so I could learn and grow and become the person I am right now. Thankful for all the nice people who believe in me and support me. One of my mottos: you are what you have made of yourself. I will never be finished. This would result in stagnation. The solution of any mathematical problem seemed so easy and elegant to me when I was young: true or false. Nothing else. Like a central theme, my interest and my ability in mathematics affect my whole life. I love mathematics! The solution of any mathematical problem seemed so easy and elegant to me when I was young: true or false. Nothing else. I wanted to immerse myself in this subject. It was not easy to continue with this wish in a male-dominated world: unmotivated teachers, incompetent advisors at the job center, traditionally-thinking professors at the technical college. Thus, my central theme evolved in a different direction. One constant in my life stayed: me reflecting on my current situation - Who am I? What have I made of myself? I grew up in a family where natural sciences and logic discussions were welcome. My parents met at the university, later becoming a math high school teacher and a physicist. In highschool, I have always been interested in math and natural sciences. I once asked my math teacher about the mathematical olympiad but I felt completely left alone by him when he didn’t show much interest and asked me to contact the organizers instead of telling me about it. It was frustrating that the lessons in math neither prepared me for the kind of exercises solved at mathematical olympiads nor showed me the possible career paths in science. The job center employee I talked to did not recommend studying math either. Thus, I chose a different path at first. While preparing for my engineering studies, I worked at a locksmithery. In this men’s world, the break room was decorated with a calendar with “aesthetic” images of women. Some old-established professors at the technical college weren’t pleased about women studying engineering. Remember: if you love something, you will get great at it. I am grateful for being able to realize what I love. I love mathematics. Finally – I just couldn’t get enough of math – I switched to studying mathematics at the university and went my way to diploma, PhD, being a mother, a teacher, a developer of final exams in math, to leadership in the climate and sustainability working group. I left the “typical” career path of mathematicians again. And came back to my profession: Now I have developed my skills in actuarial subjects working in insurances. And I will continue looking for new challenges. Right now, I am sitting on the train. Driving from Cologne to Hamburg. And I am happy living in this moment. Happy with my talent for mathematics. It helps me developing, being curious and following interesting new paths. My path leads me further to being an actuarial consultant. I am sure I will encounter interesting tasks, opportunities and people in my future. And I want to show my beloved children: it is worthwhile to look deep within yourself. Be true to yourself. Find a subject that interests you and follow your ambition. Yes, there will always be drawbacks. Fortunately, the world is not as men-dominated anymore as it has been. Remember: if you love something, you will get great at it. I am grateful for being able to realize what I love. I love mathematics.

#introduction Hello Mastodon! We are a computational #quantum #physics group at the FU Berlin. Our main areas for applying #QuantumControl strategies are dynamics in #AMO systems and #QuantumInformation processing.
We are using #CoherentControl as well as #OptimalControl on both isolated and open quantum systems.
A major part of our work is also the development of optimal control methods.

We collaborate with research groups all over Europe, Israel and the US.

Just implemented something crazy, No clue how to make it converge or whether it's even feasible 😅

Env: Cartpole + continuous action space + image observation + Frame stacking

Policy: Use CNN encoded features and predicts the state, and weights of a LQR system (A, B, Q, R) with MLP -> solves the LQR over a horizon using differentiable convex optimization with constraint on actions, output is the first optimal action.

Loss: Policy gradient on rewards

#ReinforcementLearning #OptimalControl

📣 Our latest publication, "Optimality equivalence and computational advantages of free-floating base dynamics compared to full-body dynamics," is now available in Mech and Mach Theory.
We found that free-floating dynamics can significantly improve computational efficiency, with implications for optimizing techniques in aerial acrobatics like trampolinists performing twisting somersaults. 🤸‍♀️

#introduction I'm Michael Goerz, a computational physicist working on #quantum #optimalcontrol. Initially, in the context of #quantumcomputing in open quantum systems (Rydberg atoms, ions, superconducting qubits), current applications tend towards robust #quantumsensing. Most of my time is spent developing methods and software. I have a long background in #Fortran and #Python. My primary language today is #julialang, working on the QuantumControl.jl package.

Quick #introduction 👋 ! I am an assistant professor at #princeton https://orfe.princeton.edu. I work on #realtime #optimization, #optimalcontrol, with applications in #robotics and #operationsresearch #orms. You can find more info about my research group at 🌐 https://stellato.io

Hope to see more #optimizers here soon!
