Moiré fractals in twisted graphene layers
Deepanshu Aggarwal, Rohit Narula, and Sankalpa Ghosh
Author(s): Deepanshu Aggarwal, Rohit Narula, and Sankalpa Ghosh

Fractals are ubiquitous in nature. When two-dimensional crystals such as graphene or h-BN are multiply stacked and then twisted by a specific angle, the resulting super-moiré pattern exhibits electronic fractality. The authors call these novel structures “moiré fractals”. They derive a formula that relates their fractal dimension to the number of electronic bands in a given energy window. Such a number of bands fundamentally constrains charge and heat transport, thus providing a powerful tool for engineering designer quantum materials.

Pair density wave and $\mathit{s}±\mathit{id}$ superconductivity in a strongly coupled lightly doped Kondo insulator
Fangze Liu and Zhaoyu Han
Author(s): Fangze Liu and Zhaoyu Han

We investigate the large Kondo coupling limit of the Kondo-Heisenberg model on one- and two-dimensional lattices. Focusing on the possible superconducting states when slightly doping the Kondo insulator state, we identify different pairing modes to be most stable in different parameter regimes. Poss…

Signatures of Correlated Defects in an Ultraclean Wigner Crystal in the Extreme Quantum Limit
P. T. Madathil, C. Wang, S. K. Singh, A. Gupta, K. A. Villegas Rosales, Y. J. Chung, K. W. West, K. W. Baldwin, L. N. Pfeiffer, L. W. Engel, and M. Shayegan

Low-disorder two-dimensional electron systems in the presence of a strong, perpendicular magnetic field terminate at very small Landau level filling factors in a Wigner crystal (WC), where the electrons form an ordered array to minimize the Coulomb repulsion. The nature of this exotic, many-body, qu…

Magic Angles and Fractional Chern Insulators in Twisted Homobilayer Transition Metal Dichalcogenides
Nicolás Morales-Durán, Nemin Wei, Jingtian Shi, and Allan H. MacDonald
Author(s): Nicolás Morales-Durán, Nemin Wei, Jingtian Shi, and Allan H. MacDonald

We explain the appearance of magic angles and fractional Chern insulators in twisted K-valley homobilayer transition metal dichalcogenides by mapping their continuum model to a Landau level problem. Our approach relies on an adiabatic approximation for the quantum mechanics of valence band holes in …

Effects of Molecular Noise on Cell Size Control
Motasem ElGamel and Andrew Mugler
Author(s): Motasem ElGamel and Andrew Mugler

Cells employ control strategies to maintain a stable size. Dividing at a target size (the “sizer” strategy) is thought to produce the tightest size distribution. However, this result follows from phenomenological models that ignore the molecular mechanisms required to implement the strategy. Here we…

Elasto-viscoplastic spreading: From plastocapillarity to elastocapillarity
Hugo L. França, Maziyar Jalaal, and Cassio M. Oishi
Author(s): Hugo L. França, Maziyar Jalaal, and Cassio M. Oishi

We study the spreading of elasto-viscoplastic (EVP) droplets under surface tension effects. The non-Newtonian material flows like a viscoelastic liquid above the yield stress and behaves like a viscoelastic solid below it. Hence, the droplet initially flows under surface tension forces but eventuall…
