Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: Dark photons are a theorized massive spin-1 particle which can be produced via various mechanisms, including cosmological gravitational particle production (GPP) in the early universe. In this work, we extend previous results for GPP of […]

Kavli Affiliate: Ke Wang | First 5 Authors: Wenhao He, Tongyang Li, Xiantao Li, Zecheng Li, Chunhao Wang | Summary: The optimal control problem for open quantum systems can be formulated as a time-dependent Lindbladian that is parameterized by a number of time-dependent control variables. Given an observable and an initial state, the goal is […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Leon Shaposhnikov, Eduardo Barredo-Alamilla, Frank Wilczek, Maxim A. Gorlach, | Summary: Spatial structuring of materials at subwavelength scales underlies the concept of metamaterials possessing exotic properties beyond those of the constituent media. Temporal modulation of material parameters enables further functionalities. Here, we show that high-frequency oscillations of […]
Kavli Affiliate: Stephanie Wehner | First 5 Authors: Álvaro G. Iñesta, Hyeongrak Choi, Dirk Englund, Stephanie Wehner, | Summary: Distributing quantum states reliably among distant locations is a key challenge in the field of quantum networks. One-way quantum networks address this by using one-way communication and quantum error correction. Here, we analyze quantum circuit switching […]

J. van der Zant, Samuel Mañas-Valero | Summary: The layered metamagnet CrSBr offers a rich interplay between magnetic, optical and electrical properties that can be extended down to the two-dimensional (2D) limit. Despite the […]
Kavli Affiliate: Jing Wang | First 5 Authors: Haosheng Xu, Dongheng Qian, Jing Wang, , | Summary: The use of machine learning methods for predicting the properties of crystalline materials encounters significant challenges, primarily related to input encoding, output versatility, and interpretability. Here, we introduce CrystalBERT, an adaptable transformer-based framework with novel structure that integrates […]
