To my surprise I found out that the flat bands of TMD heterobilayers automatically have a spin-orbit coupling that makes them realizations of the Kane-Mele model. This is different from the original Wu-MacDonald model where they say its a triangular lattice Hubbard model. Now on the arXiv!

At the online Moiré-Twistronics workshop last week I gave a short presentation on our work on Chern insulators in twisted bilayer graphene and twisted mono-bilayer graphene. It was a great online conference, so check their website for recordings of most other talks there.

I'm quite proud of my latest single-author paper, in which I explore a new direction in the field of disordered interacting systems. I dub it: "Few-Body Delocalization", and I investigate the question: given that single-particle states are all localized in d ≤ 2 dimen- sions, how can...

My recent density functional theory-based work on bilayer jacutingaite (Pt2HgSe3) is published in the journal Physical Review Materials!

Our work on wavefunction collapse (An experimental proposal to study spontaneous collapse of the wave function using two travelling wave parametric amplifiers, see here on arXiv) has made it to the cover of the latest issue of Physica Status Solidi (b), with some nice cover art made by the first...

The Dutch newspaper NRC Handelsblad covered our recent work on a direct detection of flat bands in twisted bilayer graphene!

Just published in Physical Review Letters, our latest work on a quantum spin glass with unusual dynamics. Spin glasses and many-body localization (MBL) are prime examples of ergodicity breaking, yet their physical origin is quite different: the former phase arises due to rugged classical energy...

The readout of a microwave qubit state occurs using an amplification chain that enlarges the quantum state to a signal detectable with a classical measurement apparatus. However, at what point in this process is the quantum state really “measured”? To investigate whether the “measurement”...

My first paper with experimental groups is now published in Nature Physics. Our work is a detailed characterization of twisted bilayer graphene, with as highlight the direct observation of flat bands using nano-ARPES. I calculated the expected ARPES spectra, which can be seen in Fig 3 and 4 of the ...

Together with the Yu Saito and Andrea Young (UC Santa Barbara) we wrote a paper about symmetry broken states in the presence of large magnetic fields in twisted bilayer graphene. Read here more about it, on the arXiv.
