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: Bo Gu | First 5 Authors: Jia-Wen Li, Zhen Zhang, Jing-Yang You, Bo Gu, Gang Su | Summary: The two-dimensional (2D) van der Waals ferromagnetic semiconductors, such as CrI$_3$ and Cr$_2$Ge$_2$Te$_6$, and the 2D ferromagnetic metals, such as Fe$_3$GeTe$_2$ and MnSe$_2$, have been obtained in recent experiments and attracted a lot of attentions.

Kavli Affiliate: Yi Zhou | First 5 Authors: Sheng Wang, Yi Zhou, , , | Summary: In this article, we prove the global well-posedness in the critical Sobolev space $H_{rad}^2left(mathbb{R}^2right) times H_{rad}^1 left(mathbb{R}^2right)$ for the radial time-like extremal hypersurface equation in $left(1+3right)$- dimensional Minkowski space-time. This is achieved by deriving a new div-curl type lemma […]
Kavli Affiliate: Huajia Wang | First 5 Authors: Liangyu Chen, Huajia Wang, , , | Summary: Causal shadows are bulk space-time regions between the entanglement wedges and the causal wedges, their existence encodes deep aspects of the entanglement wedge reconstruction in the context of subregion duality in AdS/CFT. In this paper, we study the perturbation […]

Kavli Affiliate: Gang Su | First 5 Authors: Dai-Wei Qu, Bin-Bin Chen, Xin Lu, Qiaoyi Li, Shou-Shu Gong | Summary: Recently, a robust $d$-wave superconductivity has been unveiled in the ground state of the 2D $t$-$t’$-$J$ model — with both nearest-neighbor ($t$) and next-nearest-neighbor ($t’$) hoppings — through the density matrix renormalization group calculations in […]
Kavli Affiliate: Masahiro Nozaki | First 5 Authors: Kanato Goto, Masahiro Nozaki, Kotaro Tamaoka, Mao Tian Tan, | Summary: We study the dynamical properties of a strongly scrambling quantum circuit involving a projective measurement on a finite-sized region by studying the operator entanglement entropy and mutual information (OEE and BOMI) of the dual operator state […]
