Kavli Affiliate: Misao Sasaki | First 5 Authors: Kaloian D. Lozanov, Misao Sasaki, Volodymyr Takhistov, , | Summary: Causal soliton formation (e.g. oscillons, Q-balls) in the primordial Universe is expected to give rise to a universal gravitational wave (GW) background, at frequencies smaller than scales of nonlinearity. We show that modifications of the soliton density […]

Kavli Affiliate: Renxin Xu | First 5 Authors: Chen Zhang, Yong Gao, Cheng-Jun Xia, Renxin Xu, | Summary: It was conjectured that the basic units of the ground state of bulk strong matter may be strange-clusters called strangeons, and they can form self-bound strangeon stars that are highly compact. Strangeon stars can develop a strange […]

Kavli Affiliate: Jing Wang | First 5 Authors: Linghao Huang, Jing Wang, , , | Summary: We develop a theory of the nonlinear optical responses in superconducting systems in the presence of a dc supercurrent. The optical transitions between particle-hole pair bands across the superconducting gap are allowed in clean superconductors as the inversion-symmetry-breaking by […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Makars Siskins, Yaroslav Blanter, , | Summary: We developed a theoretical scheme of incorporating the magnetoelastic contribution into the thermal elastic dynamics for the thin membranes of 2D antiferromagnetic material with restricted geometry. We extended the elastic Gr"uneisen relation into an effective version which includes […]

Kavli Affiliate: Wei Gao | First 5 Authors: Haoming Wang, Wei Gao, , , | Summary: Federated Learning (FL) can be affected by data and device heterogeneities, caused by clients’ different local data distributions and latencies in uploading model updates (i.e., staleness). Traditional schemes consider these heterogeneities as two separate and independent aspects, but this […]
