Proud to be part of this work on the quantum annealing performance within building-blocks of a Rydberg network designed for solving maximum independent set problems. This hints at a more indepth survey into how the full network provides quantum speedup to the algorithm.

It is rediculous ETHz, a top university in continental Europe, essentially bans Chinese nationals from new enrollment to master programs and employment as PhD and staff. Even more sarcastically, in the name of "die akademische Freiheit aufrechterhalten". https://t.co/lSLUTRmxsz

Happy to announce the new PRL paper from us! Combining Floquet and Keldysh, we provide a new insight into general driven-dissipative quantum systems from field theory's perspective, and apply it on BCS superconductors.

After spending 8 spendid years in the Alps, I am now looking forwards to a new adventure, in and outside of physics, back home.

[Rui Lin @RuiiiLin]

Thanks to the newly implemented MPI parallelization, MCTDH-X @ultracold_org is now able to simulate the ground state for 21 fermions in a harmonic trap! See the figure for the densities in real and momentum spaces. Can you make sense of them?

[Rui Lin @RuiiiLin]

Happy to announce our new preprint: https://t.co/c8J6hGbcdz, where we look at driven-dissipative effects in the platform of superconductors! Going beyond Lindbladian, we propose to manipulate the Floquet excitation structure seen by the bath, which leads to "cooling by drive".

[Rui Lin @RuiiiLin]

To lazy to log into a cluster? MCTDH-X @ultracold_org now runs on Mac (Apple Silicon & Intel). Why not have a try?

It was an incredible school where I learned A LOT and met so many old and new faces, and a pleasant stay in Varenna. Thanks to all the organizers and speakers!

Check out our recent demonstration of optimized observable readout from #quantum many-body states via #machinelearning with @PMolignini @RuiiiLin @miriam_buettner @LPapariello @MarioToss @AxelLode et al.: https://t.co/9VyskbqQZf

Don't miss the talk!

[Rui Lin @RuiiiLin]

Dissipation can qualitatively change the dynamics of a cavity-atom system, e.g., introducing a large family of "nearly dark" states https://t.co/uGC3Gstyyz or a non-Hermitian flow on a synthetic momentum lattice https://t.co/yxNRiEnUvL. Check them out!

[Rui Lin @RuiiiLin]

It is a real pleasure to be part of the collaboration! Another nice work where MCTDH-X @ultracold_org agrees quantitatively with experiments!

@Zilberberg_Phys Congrats!!

[Rui Lin @RuiiiLin]

@PucherSebastian @ultracold_org Thanks a lot! Yes, it was @AxelLode 's idea to try the new-fashion online journal. 😆

[Rui Lin @RuiiiLin]

As a follow-up work of https://t.co/85o7ebOdcj, we are now able to quantitatively compare the Mott transition with experimental results using MCTDH-X @ultracold_org. Shown in the figures are the experimental and simulated momentum and real space densities. Have a read!

Check out https://t.co/A6oKTVPVDQ our implementation of MCTDH-X @ultracold_org for a quantitative comparison of the Mott boundary in a cavity-BEC system with experimental results from ZOQ Hamburg. As a submission to SciPost, everyone is welcome to share their comments!

[Rui Lin @RuiiiLin]

@PMolignini @quant_phys @ultracold_org Exactly! I wonder which paper it is.

With the numerical tool MCTDH-X @ultracold_org, we simulate the many-body state of blue-detuned cavity-BEC systems. Dimerization of optical lattice and dynamical instabilities are observed/confirmed. A simple toy model explains all these phenomena and predicts a Hopf bifurcation.
