Emergent Chern-Simons Interactions in 3+1 Dimensions

Kavli Affiliate: Frank Wilczek | First 5 Authors: Marcus Stålhammar, Darya Rudneva, Thors Hans Hansson, Frank Wilczek, | Summary: Parity violating superconductors can support a low-dimension local interaction that becomes, upon condensation, a purely spatial Chern-Simons term. Solutions to the resulting generalized London equations can be obtained from solutions of the ordinary London equations with […]

TESS Spots a Super-Puff: The Remarkably Low Density of TOI-1420b

Kavli Affiliate: Sara Seager | First 5 Authors: Stephanie Yoshida, Shreyas Vissapragada, David W. Latham, Allyson Bieryla, Daniel P. Thorngren | Summary: We present the discovery of TOI-1420b, an exceptionally low-density ($rho = 0.08pm0.02$ g cm$^{-3}$) transiting planet in a $P = 6.96$ day orbit around a late G dwarf star. Using transit observations from […]

Quasi-periodic oscillations during magnetar giant flares in the strangeon star model

Kavli Affiliate: Lijing Shao | First 5 Authors: Hong-Bo Li, Yacheng Kang, Zexin Hu, Lijing Shao, Cheng-Jun Xia | Summary: Soft gamma-ray repeaters (SGRs) are widely understood as slowly rotating isolated neutron stars. Their generally large spin-down rates, high magnetic fields, and strong outburst energies render them different from ordinary pulsars. In a few giant […]

Nonlinear dynamics and magneto-elasticity of nanodrums near the phase transition

Kavli Affiliate: Herre S. J. Van Der Zant | First 5 Authors: Makars Šiškins, Ata Keşkekler, Maurits J. A. Houmes, Samuel Mañas-Valero, Eugenio Coronado | Summary: Nanomechanical resonances of two-dimensional (2D) materials are sensitive probes for condensed-matter physics, offering new insights into magnetic and electronic phase transitions. Despite extensive research, the influence of the spin […]

Stability of Taylor-Couette Flow with Odd Viscosity

Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Guangle Du, Rudolf Podgornik, , , | Summary: Odd viscosity can emerge in 3D hydrodynamics when the time reversal symmetry is broken and anisotropy is introduced. Its ramifications on the stability of the prototypical Taylor-Couette flow in curved geometries have remained unexplored. Here, we investigate the effects […]

Artificial Intelligence-based Motion Tracking in Cancer Radiotherapy: A Review

Kavli Affiliate: Jing Wang | First 5 Authors: Elahheh Salari, Jing Wang, Jacob Wynne, Chih-Wei Chang, Xiaofeng Yang | Summary: Radiotherapy aims to deliver a prescribed dose to the tumor while sparing neighboring organs at risk (OARs). Increasingly complex treatment techniques such as volumetric modulated arc therapy (VMAT), stereotactic radiosurgery (SRS), stereotactic body radiotherapy (SBRT), […]

Axion detection via superfluid $^3$He ferromagnetic phase and quantum measurement techniques

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: So Chigusa, Dan Kondo, Hitoshi Murayama, Risshin Okabe, Hiroyuki Sudo | Summary: We propose to use the nuclear spin excitation in the ferromagnetic A1 phase of the superfluid $^3$He for the axion dark matter detection. This approach is striking in that it is sensitive to the axion-nucleon […]

Optimal Photodetector Size for High-Speed Free-Space Optics Receivers

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Muhammad Salman Bashir, Qasim Zeeshan Ahmed, Mohamed-Slim Alouini, , | Summary: The selection of an optimal photodetector area is closely linked to the attainment of higher data rates in optical wireless communication receivers. If the photodetector area is too large, the channel capacity degrades due to lower […]
