Theoretical Prediction of Non-Hermitian Skin Effect in Ultracold Atom Systems

Kavli Affiliate: Fuchun Zhang | First 5 Authors: Sibo Guo, Chenxiao Dong, Fuchun Zhang, Jiangping Hu, Zhesen Yang | Summary: Non-Hermitian skin effect, which refers to the phenomenon that an extensive number of eigenstates are localized at the boundary, has been widely studied in lattice models and experimentally observed in several classical systems. In this […]

Tunable vortex Majorana modes controlled by strain in homogeneous LiFeAs

Kavli Affiliate: Fuchun Zhang | First 5 Authors: Wenyao Liu, Quanxin Hu, Xiancheng Wang, Yigui Zhong, Fazhi Yang | Summary: The iron-based superconductors (FeSCs) have recently emerged as a promising single-material Majorana platform by hosting isolated Majorana zero modes (MZMs) at relatively high temperatures. To further verify its Majorana nature and move forward to build […]

Ultrafast optical excitation of magnetic dynamics in van der Waals magnets: Coherent magnons and BKT dynamics in NiPS$_3$

Kavli Affiliate: Leon Balents | First 5 Authors: Urban F. P. Seifert, Mengxing Ye, Leon Balents, , | Summary: Optical pump-probe experiments carried out in the time domain reveal both the intrinsic low energy dynamics and its connections to higher energy excitations in correlated electron systems. In this work, we propose two microscopic mechanisms for […]

Realization of Quantum Dipoles in Triangular Lattice Crystal Ba3Yb(BO3)3

Kavli Affiliate: Leon Balents | First 5 Authors: Rabindranath Bag, Matthew Ennis, Chunxiao Liu, Sachith E. Dissanayake, Zhenzhong Shi | Summary: We investigate the thermodynamic properties of the ytterbium-based triangular lattice compound Ba3Yb(BO3)3. The results demonstrate the absence of any long-range ordering down to 56 mK. Analysis of the magnetization, susceptibility and specific heat measurements […]

A convergent inflation hierarchy for quantum causal structures

Kavli Affiliate: David Gross | First 5 Authors: Laurens T. Ligthart, Mariami Gachechiladze, David Gross, , | Summary: A causal structure is a description of the functional dependencies between random variables. A distribution is compatible with a given causal structure if it can be realized by a process respecting these dependencies. Deciding whether a distribution […]

An Arbitrary Scale Super-Resolution Approach for 3D MR Images via Implicit Neural Representation

Kavli Affiliate: Yawen Sun | First 5 Authors: Qing Wu, Yuwei Li, Yawen Sun, Yan Zhou, Hongjiang Wei | Summary: High Resolution (HR) medical images provide rich anatomical structure details to facilitate early and accurate diagnosis. In MRI, restricted by hardware capacity, scan time, and patient cooperation ability, isotropic 3D HR image acquisition typically requests […]

Stochastic Low Frequency Variability in 3-Dimensional Radiation Hydrodynamical Models of Massive Star Envelopes

Kavli Affiliate: Lars Bildsten | First 5 Authors: William C. Schultz, Lars Bildsten, Yan-Fei Jiang, , | Summary: Increasing main sequence stellar luminosity with stellar mass leads to the eventual dominance of radiation pressure in stellar envelope hydrostatic balance. As the luminosity approaches the Eddington limit, additional instabilities (beyond conventional convection) can occur. These instabilities […]

Unified Description of Tunneling Transport in Ultracold Atomic Gases

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Hiroyuki Tajima, Daigo Oue, Mamoru Matsuo, , | Summary: We derive tunneling Hamiltonians from a microscopic model of ultracold atoms separated by an external potential barrier. Not only usual one-body tunneling but also pair- and spin-tunneling processes naturally arise from a well-known microscopic model without any empirical […]
