Coherent excitation of bound electron quantum state with quantum electron wavepackets
Kavli Affiliate: Amnon Yariv | First 5 Authors: Du Ran, Bin Zhang, Reuven Ianconescu, Aharon Friedman, Jacob Scheuer | Summary: We present a fully quantum model for the excitation of a bound electron based on the free-electron bound-electron resonant interaction (FEBERI) scheme. The bound electron is modeled as a quantum two-level system (TLS) at any […]

Lifetime Limited and Tunable Quantum Light Emission in h-BN via Electric Field Modulation
Kavli Affiliate: Harry A. Atwater | First 5 Authors: Hamidreza Akbari, Souvik Biswas, Pankaj K. Jha, Joeson Wong, Benjamin Vest | Summary: Color centered-based single photon emitters in hexagonal boron nitride (h-BN) have shown promising photophysical properties as sources for quantum light emission. Despite significant advances towards such a goal, achieving lifetime-limited quantum light emission […]

A method to computationally screen for tunable properties of crystalline alloys
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Rachel Woods-Robinson, Matthew K. Horton, Kristin A. Persson, , | Summary: Conventionally, high-throughput computational materials searches start from an input set of bulk compounds extracted from material databases, and this set is screened for candidate materials for specific applications. In contrast, many functional materials, and especially […]

How Material Heterogeneity Creates Rough Fractures
Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Will Steinhardt, Shmuel M. Rubinstein, , , | Summary: Fractures are a critical process in how materials wear, weaken, and fail whose unpredictable behavior can have dire consequences. While the behavior of smooth cracks in ideal materials is well understood, it is assumed that for real, […]
