This one I’m really proud of 🤩: our new method to simulate dynamics with neural quantum states: the tNQS 🤖🕚 which directly solves the time dependent Schrödinger equation globally 🤯 led amazingly by brand new Phd student @ankavdwalle @MCQST_cluster https://t.co/re0VkKJHDP

[Jad C. Halimeh @JCHalimeh]

I am looking for excellent PhD candidates for my Max Planck Research Group Dynamical Quantum Matter Theory https://t.co/opV9MqNPJh. Candidates should also apply through the IMPRS-QST (https://t.co/Ah4xgMeXiq) and MQV (https://t.co/y2aDzwwpeB) doctoral fellowship programs.🧵1/5

Looking forward to two exciting concerts with some friends in Göttingen this weekend 🎶
Early music from the Franco-Flemish era in a cute little contemporary church ⛪️

I'm very happy to perform these lesser known, amazingly unique works

[Felix A. Palm @FelixAPalm]

This weekend, I was participating in the International Choir Competition of Flanders (IKV) in Genk with the #BrusselsChamberChoir 🎼🎶
It was a great time with an absolutely amazing outcome for BCC 🥇
I'm very happy and proud to be part of this (now award-winning) choir 🏆

[Munich Quantum Valley @MunichQuantum]

The schedule for the Quantum Talents Symposium, organized by @MCQST_cluster with support from MQV, is now finalized! The event will showcase groundbreaking research from early-career scientists in QST world-wide.

4/4 By systematically varying the number of legs and monitoring the appearance and disappearance of the various ground state phases, our work highlights the importance of finite-size effects for the realization of exotic states in experimentally realistic systems.

3/4 We supplemented our simulations by exact diagonalization of small systems. The particle entanglement spectrum (PES) shows evidence for the Pfaffian state in a narrow regime in sufficiently isotropic systems (5 legs and more).

🚆 Back in Dresden once again for this week's workshop on "geometry and non-adiabatic responses in non-equilibrium systems" @mpi_pks

[Pieter Claeys @Pieter_Cl]

We're again organizing a school for master students @mpi_pks , this year on the topic of "Collective Phenomena in Quantum Many-Body Physics: From Quantum Matter to Light"!

📜📢 New paper on the https://t.co/VdSn8Dhsrb 🥳

Together with Fabian Pauw, @aBohrdt and Sebastian Paeckel (@Topo_Logic), we @QManyBody investigated the detection of hidden order in fractional Chern insulators.

Topology + cold atoms + MPS methods = a very fun project!

5/5 Recently, Ledinauskas & Anisimovas studied a hard-core bosonic Hofstadter-Hubbard model using a multi-layer perceptron and convolutional neural networks. Similar to us, they found that strong magnetic flux complicates the simulations: https://t.co/251PkDJgaF

4/5 At blockade radii larger than the magnetic length, we find bubble crystals and Wigner crystals. The bubble crystal phase might serve as a starting point for the for clustered liquid phases, possibly hosting non-Abelian anyons.
