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 […]

Multi-Particle Tunneling Transport at Strongly-Correlated Interfaces

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Hiroyuki Tajima, Daigo Oue, Mamoru Matsuo, , | Summary: We elucidate the multi-particle transport of pair- and spin-tunnelings in strongly correlated interfaces. Not only usual single-particle tunneling but also interaction-induced multi-particle tunneling processes naturally arise from a conventional microscopic model without any empirical parameters, through the overlap […]

Valley transport driven by dynamic lattice distortion

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Yuya Ominato, Daigo Oue, Mamoru Matsuo, , | Summary: Angular momentum conversion between mechanical rotation and the valley degree of freedom in 2D Dirac materials is investigated theoretically. Coupling between the valley and vorticity of dynamic lattice distortions is derived by applying the k.p method to 2D […]
