New paper where we microscopically observe spin polarons in a triangular Fermi-Hubbard system! Kinetic frustration in triangular lattices leads to the formation of polarons that can exist in the absence of superexchange and are robust at high temperatures.

@SimonLCornish Fantastic work!

@adamdzwright @PrincetonChem @acsJACS congratulations!

@spurious_bows congratulations! amazing work.

[Lysander Christakis @LEChristakis]

@GoMagicOfficial they all sound very useful but i am most interested in the basic invasions course right now. The Ko one would also be very helpful.

The researchers cooled molecules down to ultracold temperatures, loaded them into a crystal of light known as an optical lattice, and studied their collective quantum behavior such that each individual molecule could be observed. @PrincetonPhys https://t.co/6AdaldXeSR

A #PrincetonU experiment could have profound implications for fundamental physics research and accelerate the development of large-scale quantum computer systems. ⬇️ https://t.co/izcCoJVRxZ

@quantenvogel We actually tried briefly to do this, and we did see some kind of long-range correlations after the ramp, but due to some technical noise it wasn't very clear so we moved on. Should be solvable in the future though. Also it should be possible to use multiple rotational states!

[Lysander Christakis @LEChristakis]

Check out our new paper from the Bakr lab! We use ultracold molecules in an optical lattice to simulate an interacting spin model, and then probe the growth of correlations between the spins in time with microscopic resolution https://t.co/BjCBY5y7pT

[Lysander Christakis @LEChristakis]

@quantenvogel Thank you! To do that, instead of doing the quench dynamics that we show here, you would want to do an adiabatic ramp to the ground state. Then you should see a transition between exponential to algebraic correlations as you ramp slowly into the superfluid phase. Future work :)

[Lysander Christakis @LEChristakis]

I also had a ton of fun working with my colleagues @laser_cooled @aormorningstar and everyone else at @PrincetonPhys on this project.

[Lysander Christakis @LEChristakis]

I'm excited about this paper because it took almost 5 years of work to build the instrument and collect the data for these results, but it was worth it because I think these experiments really demonstrate the power of ultracold molecules for studying quantum many-body physics.

Latest work from the Bakr Lab https://t.co/sbNPl1Wa59! We scale our Fermi-Hubbard optical tweezer platform to 2-dimensions, where we realize a variety of programmable lattice geometries using a stroboscopic technique.
