Kavli Affiliate: Anthony Challinor | First 5 Authors: Nicholas Choustikov, Zvonimir Vlah, Anthony Challinor, , | Summary: Perturbation theory is a powerful tool for studying large-scale structure formation in the universe and calculating observables such as the power spectrum or bispectrum. However, beyond linear order, typically this is done by assuming a simplification in the […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Yan-Qi Wang, Michał Papaj, Joel E. Moore, , | Summary: Gapless helical edge modes are a hallmark of the quantum spin Hall effect. Protected by time-reversal symmetry, each edge contributes a quantized zero-temperature conductance quantum $G_0 equiv e^2/h$. However, the experimentally observed conductance in WTe$_2$ decreases […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Yongli Zhu, Xiang Zhang, Renchang Dai | Summary: This paper proposes an electronic circuit simulator-based method to accelerate the power system transient simulation, where the modeling of a generic HVDC (High Voltage Direct Current) system is focused. The electronic circuit simulation equations and the backward differentiation formula […]
Kavli Affiliate: Feng Wang | First 5 Authors: Ruoqi Wang, Zhuoyang Chen, Qiong Luo, Feng Wang, | Summary: In radio astronomy, signals from radio telescopes are transformed into images of observed celestial objects, or sources. However, these images, called dirty images, contain real sources as well as artifacts due to signal sparsity and other factors. […]

Kavli Affiliate: Frank Wilczek | First 5 Authors: Michael P. Zaletel, Mikhail Lukin, Christopher Monroe, Chetan Nayak, Frank Wilczek | Summary: The spontaneous breaking of time translation symmetry has led to the discovery of a new phase of matter – the discrete time crystal. Discrete time crystals exhibit rigid subharmonic oscillations, which result from a […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Hiroyuki Tajima, Hiroshi Funaki, Yuta Sekino, Nobutoshi Yasutake, Mamoru Matsuo | Summary: We explore the theoretical possibility of $^3P_0$ neutron superfluid in dilute spin-polarized neutron matter, which may be relevant to the crust region of a magnetized neutron star. In such a dilute regime where the neutron […]

Kavli Affiliate: Feng Wang | First 5 Authors: Guorui Chen, Ya-Hui Zhang, Aaron Sharpe, Zuocheng Zhang, Shaoxin Wang | Summary: Wigner crystals are predicted as the crystallization of the dilute electron gas moving in a uniform background when the electron-electron Coulomb energy dominates the kinetic energy. The Wigner crystal has previously been observed in the […]
Kavli Affiliate: Rui Costa | Authors: Vivek Ravindra Athalye, Preeya Khanna, Suraj Gowda, Amy L Orsborn, Rui M Costa and Jose M Carmena | Summary: It has been proposed that the nervous system has the capacity to generate a wide variety of movements because it re-uses some invariant code. Previous work has identified that dynamics […]
