Entangled light-matter interactions and spectroscopy

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Szilard Szoke, Hanzhe Liu, Bryce P. Hickam, Manni He, Scott K. Cushing | Summary: Entangled photons exhibit non-classical light-matter interactions that create new opportunities in materials and molecular science. For example, in entangled two-photon absorption, the intensity-dependence scales linearly as if only one photon was present. […]

Strong Circular Dichroism in Single Gyroid Optical Metamaterials

Kavli Affiliate: Ulrich Wiesner | First 5 Authors: Cédric Kilchoer, Narjes Abdollahi, James A. Dolan, Doha Abdelrahman, Matthias Saba | Summary: Over the past two decades, metamaterials have led to an increasing number of biosensing and nanophotonic applications due to the possibility of a careful control of light propagating through subwavelength features. Chiral nanostructures (characterized […]

Defect dynamics in growing bacterial colonies

Kavli Affiliate: Sander Tans | First 5 Authors: Duco van Holthe tot Echten, Gerhard Nordemann, Martijn Wehrens, Sander Tans, Timon Idema | Summary: Colonies of rod-shaped bacteria constitute a system of colloidal active matter with nematic properties. As a single initial bacterium multiplies through repeated divisions, the resulting colony quickly loses long-range orientational order, but […]

Quantum diffusion of microcavity solitons

Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Chengying Bao, Myoung-Gyun Suh, Boqiang Shen, Kemal Şafak, Anan Dai | Summary: Coherently-pumped (Kerr) solitons in an ideal optical microcavity are expected to undergo random quantum motion that determines fundamental performance limits in applications of soliton microcombs. Here, this diffusive motion and its impact on Kerr […]

Extent of Fermi-surface reconstruction in the high-temperature superconductor HgBa$_2$CuO$_{4+δ}$

Kavli Affiliate: Brad J. Ramshaw | First 5 Authors: Mun K. Chan, Ross D. McDonald, Brad J. Ramshaw, Jon B. Betts, Arkady Shekhter | Summary: High magnetic fields have revealed a surprisingly small Fermi-surface in underdoped cuprates, possibly resulting from Fermi-surface reconstruction due to an order parameter that breaks translational symmetry of the crystal lattice. […]

Enhancing a Near-Term Quantum Accelerator’s Instruction Set Architecture for Materials Science Applications

Kavli Affiliate: Leonardo Dicarlo | First 5 Authors: Xiang Zou, Shavindra P. Premaratne, M. Adriaan Rol, Sonika Johri, Viacheslav Ostroukh | Summary: Quantum computers with tens to hundreds of noisy qubits are being developed today. To be useful for real-world applications, we believe that these near-term systems cannot simply be scaled-down non-error-corrected versions of future […]

Scaling down an insect-size microrobot, HAMR-VI into HAMR-Jr

Kavli Affiliate: Robert J. Wood | First 5 Authors: Kaushik Jayaram, Jennifer Shum, Samantha Castellanos, E. Farrell Helbling, Robert J. Wood | Summary: Here we present HAMR-Jr, a SI{22.5}{millimeter}, SI{320}{milligram} quadrupedal microrobot. With eight independently actuated degrees of freedom, HAMR-Jr is, to our knowledge, the most mechanically dexterous legged robot at its scale and is […]

Incorporating electronic information into Machine Learning potential energy surfaces via approaching the ground-state electronic energy as a function of atom-based electronic populations

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Xiaowei Xie, Kristin A. Persson, David W. Small, , | Summary: Machine Learning (ML) approximations to Density Functional Theory (DFT) potential energy surfaces (PESs) are showing great promise for reducing the computational cost of accurate molecular simulations, but at present they are not applicable to varying […]
