AETHER workshop at ETH Zurich

This week we hosted the first-ever AETHER workshop at Department of Physics (D-PHYS), ETH Zurich, bringing together the developers and scientists behind the new high-performance package for the simulation of fermionic ultracold atomic systems.

The workshop gathered researchers from Stockholm University, EPFL, University of Jyväskylä, Politecnico di Milano, and ETH Zürich for several intense and highly productive days. We discussed the latest developments of the code, tested new implementations, merged branches, optimized workflows, and planned the next milestones for the project.

I personally think this event was very successful and exactly the kind of collaborative environment needed to push a major scientific software project forward!

A huge thank you to all participants for the excellent discussions, ideas, debugging sessions, and contributions throughout the week!

The next big goals are already laid out:
🚀 A first public release of AETHER this summer
📘 A full tutorial and documentation package
📄 Multiple papers currently in preparation on topics including:
• Long-range interactions
• Spin hydrodynamics
• Cavity-mediated interactions

And of course, no workshop would be complete without some good food and social time — including a successful pizza night 🍕🙂

Exciting times ahead for the project and the growing AETHER community!



MCTDH-X featured at QSCP XVII!

Last week, Paolo and Elke attended the QSCP XVII conference in Paris - a very famous interdisciplinary conference bridging quantum physics and quantum chemistry, now at its 27th iteration!

We presented new and exciting results from MCTDH-X calculations and had great conversations with other colleagues working on similar topics!

 

New paper in New Journal of Physics!

A new research article using MCTDH-X was published in New Journal of Physics by collaborators Anal Bhowmik and Ofir Alon.

The paper is titled "Interference of longitudinal and transversal fragmentations in the Josephson tunneling dynamics of Bose–Einstein condensates". This study explores how initial transverse fragmentation affects the tunneling dynamics of bosons in a Josephson junction, revealing that interference between longitudinal and transverse fragmentations leads to accelerated revival processes and distinct many-body effects absent in mean-field dynamics. 

New paper in "Atoms"

"Many-Body Effects in a Composite Bosonic Josephson Junction" -- a work by Sudip Kumar Haldar and Anal Bhowmik using MCTDHB was published in the journal Atomshttps://doi.org/10.3390/atoms12120066

 

New arxiv paper out: Rotation quenches in trapped bosonic systems

Our team members Rhombik, Sunayana, and their group leader Ofir Alon wrote another paper on simulating rotation quenches in BECs with MCTDH-X! Take a look: https://arxiv.org/abs/2411.06163
