Germanium wafers for strained quantum wells with low disorder

Kavli Affiliate: Menno Veldhorst | First 5 Authors: Lucas E. A. Stehouwer, Alberto Tosato, Davide Degli Esposti, Davide Costa, Menno Veldhorst | Summary: We grow strained Ge/SiGe heterostructures by reduced-pressure chemical vapor deposition on 100 mm Ge wafers. The use of Ge wafers as substrates for epitaxy enables high-quality Ge-rich SiGe strain-relaxed buffers with a […]

Extreme mass-ratio inspiral of a spinning body into a Kerr black hole I: Evolution along generic trajectories

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Lisa V. Drummond, Alexandra G. Hanselman, Devin R. Becker, Scott A. Hughes, | Summary: The study of spinning bodies moving in curved spacetime has relevance to binary black hole systems with large mass ratios, as well as being of formal interest. At zeroth order in a […]

Colloquium: Quantum and Classical Discrete Time Crystals

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 […]

Exploring $^3P_0$ Superfluid in Dilute Spin-Polarized Neutron Matter

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 […]

Magnetic field stabilized Wigner crystal states in a graphene moiré superlattice

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 […]
