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 Yuan | First 5 Authors: Huaisong Zhao, Peng Zou, Feng Yuan, , | Summary: By calculating the dynamical structure factor along the high symmetry directions in the Brillouin zone, the dynamical excitations of attractive Fermi-Hubbard model in a two-dimensional square optical lattice are studied with random phase approximation. {Two kinds of collective […]
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 […]
Kavli Affiliate: Jia Liu | First 5 Authors: Yuxuan He, Jia Liu, Xiaolin Ma, Xiao-Ping Wang, | Summary: We present a scalar-driven sterile neutrino production model where the interaction with the ultralight scalar field modifies the oscillation production of sterile neutrinos in the early universe. The model effectively suppresses the production of sterile neutrinos at […]
Kavli Affiliate: Alireza Marandi | First 5 Authors: Tsung-Han Wu, Luis Ledezma, Connor Fredrick, Pooja Sekhar, Ryoto Sekine | Summary: The introduction of nonlinear nanophotonic devices to the field of optical frequency comb metrology has enabled new opportunities for low-power and chip-integrated clocks, high-precision frequency synthesis, and broad bandwidth spectroscopy. However, most of these advances […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Rajan Plumley, Sathya Chitturi, Cheng Peng, Tadesse Assefa, Nicholas Burdet | Summary: With the introduction of x-ray free electron laser sources around the world, new scientific approaches for visualizing matter at fundamental length and time-scales have become possible. As it relates to magnetism and “magnetic-type” systems, advanced […]
