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: Menno Veldhorst | First 5 Authors: Kushagra Aggarwal, Andrea Hofmann, Daniel Jirovec, Ivan Prieto, Amir Sammak | Summary: Hole gases in planar germanium can have high mobilities in combination with strong spin-orbit interaction and electrically tunable g-factors, and are therefore emerging as a promising platform for creating hybrid superconductor-semiconductor devices. A key challenge […]
Kavli Affiliate: Gary A. Steele | First 5 Authors: Byoung-moo Ann, Wouter Kessels, Gary. A. Steele, , | Summary: Driving quantum systems periodically in time plays an essential role in the coherent control of quantum states. The rotating wave approximation (RWA) is a good approximation technique for weak and nearly-resonance driven fields. However, these experiments […]
Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Anais Abramian, Emmanuel Virot, Emilio Lozano, Shmuel M. Rubinstein, Tobias M. Schneider | Summary: From soda cans to space rockets, thin-walled cylindrical shells are abundant, offering exceptional load carrying capacity at relatively low weight. However, the actual load at which any shell buckles and collapses is […]
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: Michael Wimmer | First 5 Authors: Kim Pöyhönen, Daniel Varjas, Michael Wimmer, Anton R. Akhmerov, | Summary: Platforms for creating Majorana quasiparticles rely on superconductivity and breaking of time-reversal symmetry. By studying continuous deformations to known trivial states, we find that the relationship between superconducting pairing and time reversal breaking imposes rigorous bounds […]
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 […]
Kavli Affiliate: Johannes Lehmann | First 5 Authors: Tobias Winkler, Johannes Lehmann, Joost-Pieter Katoen, , | Summary: State-of-the-art probabilistic model checkers perform verification on explicit-state Markov models defined in a high-level programming formalism like the PRISM modeling language. Typically, the low-level models resulting from such program-like specifications exhibit lots of structure such as repeating subpatterns. […]
Kavli Affiliate: Graham R. Fleming | First 5 Authors: Akihito Ishizaki, Graham R. Fleming, , , | Summary: Giant strides in ultrashort laser pulse technology have enabled real-time observation of dynamical processes in complex molecular systems. Specifically, the discovery of oscillatory transients in the two-dimensional electronic spectra of photosynthetic systems stimulated a number of theoretical […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Kirsti Pajunen, Paolo Celli, Chiara Daraio, , | Summary: In this letter, we provide experimental evidence of bandgap tunability with global prestrain in additively-manufactured tensegrity-inspired lattice structures. These lattices are extremely lightweight and designed to exhibit a nonlinear compressive response that mimics that of a tensegrity structure. […]
