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. arxiv.org/pdf/2308.12951

Today, Stanford graduate workers have announced our intent to unionize! Follow along and join us in solidarity as we fight to make Stanford a fair and safe workplace by giving graduate workers a real voice in our wellbeing. Stanford works because WE do! #StanfordGWU #SGWU

Huge results from the @Holland_ConnorM and the Cheuk Lab with the first demonstration of on demand entanglement between individually prepared molecules arxiv.org/pdf/2210.06309.pdf

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 arxiv.org/abs/2207.09328

Huge results from the Bakr Lab molecule experiment! I remember talking to an excited @LEChristakis over four years ago, when there was basically no experimental setup, about the potential to do a measurement like this one with molecules in a quantum gas microscope. Congrats :)

Latest work from the Bakr Lab arxiv.org/abs/2203.15023! We scale our Fermi-Hubbard optical tweezer platform to 2-dimensions, where we realize a variety of programmable lattice geometries using a stroboscopic technique.

Further, we initialize near zero initial entropy states using a new bilayer spin-charge readout scheme. By preparing a 2x2 Hubbard plaquette, we demonstrate all components of a programmable fermion quantum simulator. Theory collaboration with @QuantumHazzard and team as well!

Bummed that Fermi-Hubbard model experiments aren't flexible enough? Or cold enough? Waseem Bakr's group (@bspar) has a solution: programmable Hubbard models w atoms in tweezers. Programmable geometry & record-low entropy. Happy to play a small role. arxiv.org/abs/2203.15023

The MLB website without any references to baseball players is accidentally an extremely compelling display of what companies have without their workers. Nothing. They can’t make anything, they can’t do anything, there is nothing interesting about them. They have nothing
Shortly after the MLB lockout, here's the current MLB.com homepage. Stories about active players have been removed.

Congratulations to @LEChristakis and Jason on the first results from the molecule microscope!
I'm excited to share the latest preprint from the Bakr lab, where we observe the Hanbury Brown and Twiss effect with ultracold molecules for the first time: arxiv.org/abs/2111.09426

Check out our latest work (and my first “first author” paper!) on realizing a bottom-up Fermi-Hubbard lattice using an optical tweezer array! arxiv.org/pdf/2110.15398.pdf
