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 […]

What can galaxy shapes tell us about physics beyond the standard model?

Kavli Affiliate: David N. Spergel | First 5 Authors: Oliver H. E. Philcox, Morgane J. König, Stephon Alexander, David N. Spergel, | Summary: The shapes of galaxies trace scalar physics in the late-Universe through the large-scale gravitational potential. Are they also sensitive to higher-spin physics? We present a general study into the observational consequences of […]

Sympathetic Mechanism for Vibrational Condensation Enabled by Polariton Optomechanical Interaction

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Vladislav Yu. Shishkov, Evgeny S. Andrianov, Sergei Tretiak, K. Birgitta Whaley, Anton V. Zasedatelev | Summary: We demonstrate a macro-coherent regime in exciton-polariton systems, where nonequilibrium polariton Bose–Einstein condensation coexists with macroscopically occupied vibrational states. Strong exciton-vibration coupling induces an effective optomechanical interaction between cavity polaritons and […]

Topological K-theory of quasi-BPS categories of symmetric quivers with potential

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: In previous works, we introduced and studied certain categories called quasi-BPS categories associated to symmetric quivers with potential, preprojective algebras, and local surfaces. They have properties reminiscent of BPS invariants/ cohomologies in enumerative geometry, for example they play important […]
