Kavli Affiliate: Boris I. Shraiman | First 5 Authors: Dillon J. Cislo, Anastasios Pavlopoulos, Boris I. Shraiman, , | Summary: How does growth encode form in developing organisms? Many different spatiotemporal growth profiles may sculpt tissues into the same target 3D shapes, but only specific growth patterns are observed in animal and plant development. In […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Li-Mei Chen, Tyler D. Ellison, Meng Cheng, Peng Ye, Ji-Yao Chen | Summary: We study a $mathbb{Z}_3$ Kitaev model on the honeycomb lattice with nearest neighbor interactions. Based on matrix product state simulations and symmetry considerations, we find evidence that, with ferromagnetic isotropic couplings, the model realizes […]

Kavli Affiliate: Shenghan Jiang | First 5 Authors: Yixin Ma, Shenghan Jiang, Chao Xu, , | Summary: The quantum spin hall (QSH) phase, also known as the two-dimensional topological insulator, hosts helical edge modes protected by time-reversal symmetry. While first proposed as a band insulator, this phase can also be realized in strongly-correlated systems, where […]
Kavli Affiliate: Shenghan Jiang | First 5 Authors: Yixin Ma, Shenghan Jiang, Chao Xu, , | Summary: The quantum spin hall (QSH) phase, also known as the 2D topological insulator, is characterized by protected helical edge modes arising from time reversal symmetry. While initially proposed for band insulators, this phase can also manifest in strongly-correlated […]
Kavli Affiliate: Leon Balents | First 5 Authors: Qingkai Meng, Jianting Dong, Pan Nie, Liangcai Xu, Jinhua Wang | Summary: Whenever the elastic energy of a solid depends on magnetic field, there is a magnetostrictive response. Field-linear magnetostriction implies piezomagnetism and vice versa. Here, we show that Mn$_3$Sn, a non-collinear antiferromanget with Weyl nodes, hosts […]

Kavli Affiliate: Leon Balents | First 5 Authors: Aleksandar Razpopov, David A. S. Kaib, Steffen Backes, Leon Balents, Stephen D. Wilson | Summary: Motivated by recent reports of a quantum disordered ground state in the triangular lattice compound NaRuO$_2$, we derive a $j_{rm eff}=1/2$ magnetic model for this system by means of first-principles calculations. The […]
Kavli Affiliate: David Gross | First 5 Authors: Laurens T. Ligthart, David Gross, , , | Summary: It is a fundamental but difficult problem to characterize the set of correlations that can be obtained by performing measurements on quantum mechanical systems. The problem is particularly challenging when the preparation procedure for the quantum states is […]
