Kavli Affiliate: Kristin A. Persson | First 5 Authors: Rachel Woods-Robinson, Vladan Stevanović, Stephan Lany, Karen N. Heinselman, Kristin A. Persson | Summary: In materials science, it is often assumed that ground state crystal structures predicted by density functional theory are the easiest polymorphs to synthesize. Ternary nitride materials, with many possible metastable polymorphs, provide […]

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Guorui Chen, Aaron L. Sharpe, Eli J. Fox, Shaoxin Wang, Bosai Lyu | Summary: The flat bands resulting from moir’e superlattices in magic-angle twisted bilayer graphene (MATBG) and ABC-trilayer graphene aligned with hexagonal boron nitride (ABC-TLG/hBN) have been shown to give rise to fascinating correlated electron […]
Kavli Affiliate: Alex Zettl | First 5 Authors: Jeffrey D. Cain, Sehoon Oh, Amin Azizi, Scott Stonemeyer, Mehmet Dogan | Summary: Imposing additional confinement in two-dimensional (2D) materials can yield further control over the associated electronic, optical, and topological properties. However, synthesis of ultra-narrow nanoribbons (NRs) remains a challenge, particularly for the transition metal dichalcogenides […]
Kavli Affiliate: Kristin Persson | First 5 Authors: Amalie Trewartha, John Dagdelen, Haoyan Huo, Kevin Cruse, Zheren Wang | Summary: The ongoing COVID-19 pandemic has had far-reaching effects throughout society, and science is no exception. The scale, speed, and breadth of the scientific community’s COVID-19 response has lead to the emergence of new research literature […]

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Dahvyd Wing, Guy Ohad, Jonah B. Haber, Marina R. Filip, Stephen E. Gant | Summary: Accurate prediction of fundamental band gaps of crystalline solid state systems entirely within density functional theory is a long standing challenge. Here, we present a simple and inexpensive method that achieves […]
Kavli Affiliate: Michael F. Crommie | First 5 Authors: Dimas G. de Oteyza, Alejandro Pérez Paz, Yen-Chia Chen, Zahra Pedramrazi, Alexander Riss | Summary: We investigate the thermally-induced cyclization of 1,2 – bis(2 – phenylethynyl)benzene on Au(111) using scanning tunneling microscopy and computer simulations. Cyclization of sterically hindered enediynes is known to proceed via two […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Pasquale Cilibrizzi, Xiaoze Liu, Peiyao Zhang, Chenzhe Wang, Quanwei Li | Summary: The newly discovered valley degree of freedom in atomically thin two-dimensional transition metal dichalcogenides offers a promising platform to explore rich nonlinear physics, such as spinor Bose-Einstein condensate (BEC) and novel valleytronics applications. However, the […]
Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: William J. Huggins, Sam McArdle, Thomas E. O’Brien, Joonho Lee, Nicholas C. Rubin | Summary: Contemporary quantum computers have relatively high levels of noise, making it difficult to use them to perform useful calculations, even with a large number of qubits. Quantum error correction is expected […]
