Hubbard Model on Triangular Lattice: Role of Charge Fluctuations

Kavli Affiliate: Zheng Zhu | First 5 Authors: Ji-Si Xu, Zheng Zhu, Kai Wu, Zheng-Yu Weng, | Summary: A chiral spin liquid (CSL) phase has been recently reported in the Hubbard model on a triangular lattice at half-filling. It emerges in an intermediate coupling regime, which is sandwiched between a $120^circ$ antiferromagnetic (AFM) phase and […]

WiCo: Win-win Cooperation of Bottom-up and Top-down Referring Image Segmentation

Kavli Affiliate: Cheng Peng | First 5 Authors: Zesen Cheng, Peng Jin, Hao Li, Kehan Li, Siheng Li | Summary: The top-down and bottom-up methods are two mainstreams of referring segmentation, while both methods have their own intrinsic weaknesses. Top-down methods are chiefly disturbed by Polar Negative (PN) errors owing to the lack of fine-grained […]

Emergent conformal boundaries from finite-entanglement scaling in matrix product states

Kavli Affiliate: Long Zhang | First 5 Authors: Rui-Zhen Huang, Long Zhang, Andreas M. Läuchli, Jutho Haegeman, Frank Verstraete | Summary: The use of finite entanglement scaling with matrix product states (MPS) has become a crucial tool for studying 1+1d critical lattice theories, especially those with emergent conformal symmetry. We argue that finite entanglement introduces […]

Turbulence Supported Massive Star Envelopes

Kavli Affiliate: Lars Bildsten | First 5 Authors: William Schultz, Lars Bildsten, Yan-Fei Jiang, , | Summary: The outer envelopes of massive ($Mgtrsim10,M_{odot}$) stars exhibit large increases in opacities from forests of lines and ionization transitions (particularly from iron and helium) that trigger near-surface convection zones. One-dimensional models predict density inversions and supersonic motions that […]

Realization of two-sublattice exchange physics in the triangular lattice compound Ba3Er(BO3)3

Kavli Affiliate: Leon Balents | First 5 Authors: Matthew Ennis, Rabindranath Bag, Chunxiao Liu, Sachith E. Dissanayake, Alexander I. Kolesnikov | Summary: We have synthesized high-quality single crystal samples of the erbium-based triangular lattice compound Ba3Er(BO3)3. Thermal and magnetic measurements reveal large anisotropy and a possible phase transition at 100 mK. The low-temperature magnetic heat […]

Machine learning enabled experimental design and parameter estimation for ultrafast spin dynamics

Kavli Affiliate: Cheng Peng | First 5 Authors: Zhantao Chen, Cheng Peng, Alexander N. Petsch, Sathya R. Chitturi, Alana Okullo | Summary: Advanced experimental measurements are crucial for driving theoretical developments and unveiling novel phenomena in condensed matter and material physics, which often suffer from the scarcity of facility resources and increasing complexities. To address […]

Kavli Affiliate: Leon Balents | First 5 Authors: Leonie Woodland, Izabella Lovas, M. Telling, D. Prabhakaran, Leon Balents | Summary: We present experimental and theoretical evidence of novel bound state formation in the low transverse field ordered phase of the quasi-one-dimensional Ising-like material CoNb$_2$O$_6$. High resolution single crystal inelastic neutron scattering measurements observe that small […]

Universality of the cross entropy in $mathbb{Z}_2$ symmetric monitored quantum circuits

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Maria Tikhanovskaya, Ali Lavasani, Matthew P. A. Fisher, Sagar Vijay, | Summary: The linear cross-entropy (LXE) has been recently proposed as a scalable probe of the measurement-driven phase transition between volume- and area-law-entangled phases of pure-state trajectories in certain monitored quantum circuits. Here, we demonstrate […]
