Kavli Affiliate: Michael Crommie | First 5 Authors: Zuocheng Zhang, Emma C. Regan, Danqing Wang, Wenyu Zhao, Shaoxin Wang | Summary: Moir’e superlattices in van der Waals heterostructures have emerged as a powerful tool for engineering novel quantum phenomena. Here we report the observation of a correlated interlayer exciton insulator in a double-layer heterostructure composed […]
Kavli Affiliate: David T. Limmer | First 5 Authors: Avishek Das, Benjamin Kuznets-Speck, David T. Limmer, , | Summary: Active matter represents a broad class of systems that evolve far from equilibrium due to the local injection of energy. Like their passive analogues, transformations between distinct metastable states in active matter proceed through rare fluctuations, […]
Kavli Affiliate: Michael Crommie | First 5 Authors: Cong Su, Fang Zhang, Salman Kahn, Brian Shevitski, Jingwei Jiang | Summary: Color center is a promising platform for quantum technologies, but their application is hindered by the typically random defect distribution and complex mesoscopic environment. Employing cathodoluminescence, we demonstrate that an ultraviolet-emitting single photon emitter can […]

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Tiancong Zhu, Wei Ruan, Yan-Qi Wang, Hsin-Zon Tsai, Shuopei Wang | Summary: One-dimensional electron systems (1DESs) exhibit properties that are fundamentally different from higher-dimensional systems. For example, electron-electron interactions in 1DESs have been predicted to induce Tomonaga-Luttinger liquid behavior. Naturally-occurring grain boundaries in single-layer semiconducting transition […]
Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Yulong Dong, K. Birgitta Whaley, Lin Lin, , | Summary: Hamiltonian simulation is one of the most important problems in quantum computation, and quantum singular value transformation (QSVT) is an efficient way to simulate a general class of Hamiltonians. However, the QSVT circuit typically involves multiple […]

Kavli Affiliate: Joel E. Moore | First 5 Authors: Björn Sbierski, Max Geier, An-Ping Li, Matthew Brahlek, Robert G. Moore | Summary: The combination of two-dimensional Dirac surface states with s-wave superconductivity is expected to generate localized topological Majorana zero modes in vortex cores. Putative experimental signatures of these modes have been reported for heterostructures […]
Kavli Affiliate: Graham R. Fleming | First 5 Authors: Yusuke Yoneda, Eric A. Arsenault, Kaydren Orcutt, Masakazu Iwai, Graham R. Fleming | Summary: Photosystem II is crucial for life on Earth as it provides oxygen as a result of photoinduced electron transfer and water splitting reactions. The excited state dynamics of the photosystem II-reaction center […]
Kavli Affiliate: Ali Javey | First 5 Authors: Hyungjin Kim, Shiekh Zia Uddin, Naoki Higashitarumizu, Eran Rabani, Ali Javey | Summary: Most optoelectronic devices operate at high photocarrier densities, where all semiconductors suffer from enhanced nonradiative recombination. Nonradiative processes proportionately reduce photoluminescence (PL) quantum yield (QY), a performance metric that directly dictates the maximum device […]
