Reducing hardware requirements for entanglement distribution via joint hardware-protocol optimization

Posted by dbos Delft

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Adrià Labay-Mora, Francisco Ferreira da Silva, Stephanie Wehner, , | Summary: We conduct a numerical investigation of fiber-based entanglement distribution over distances of up to 1600km using a chain of processing-node quantum repeaters. We determine minimal hardware requirements while simultaneously optimizing over protocols for entanglement generation and […]

Emergent Chern-Simons Interactions in 3+1 Dimensions

Posted by dbos MIT

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

Posted by dbos MIT

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

Posted by dbos Peking

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

Posted by dbos Delft

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

Posted by dbos UCAS

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

Posted by dbos Peking

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

Posted by dbos Tokyo

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 […]
