Tailoring Defects in Photonic Time Crystals for Coherent Energy Control
arXiv:2605.30633v1 Announce Type: new Abstract: Recent advances in time-varying photonics have revealed new degrees of freedom for manipulating optical states, arising from the distinctive nature of the temporal axis: causality and open-system dynamics. A representative example is photonic time crystals (PTCs) characterized by discrete time-translational symmetry, which exhibit space-analogous yet distinct phenomena, such as momentum gaps and amplifying-decaying Floquet-mode pairs. Although...
Chip-scale 'acoustic atom' controls sound waves to imitate atomic energy levels and advance computing
Chip-scale 'acoustic atom' controls sound waves to imitate atomic energy levels and advance computing Stephanie Baum Scientific Editor Robert Egan Associate Editor For every action, there is an equal and opposite reaction. What goes up must come down. Physical laws like these govern all of the natural world—except for the tiny internal components of today's microprocessors, which operate according to the unique and complicated rules of quantum physics.
Roles of individual pigments in ultrafast excitation dynamics of light-harvesting phycobiliproteins revealed by recombinant techniques and two-dimensional electronic spectroscopy
Announce Type: replace Abstract: Phycobiliproteins serve as highly efficient light-harvesting antennae in cyanobacteria, yet the molecular factors governing their ultrafast energy relaxation and coherence dynamics remain incompletely understood. In this study, we investigate the role of pigment arrangement and pigment-protein interactions by combining recombinant protein engineering with two-dimensional electronic spectroscopy (2D-ES). In addition to wild-type allophycocyanin (APC) and...
Topological antilaser
arXiv:2601.17719v2 Announce Type: replace Abstract: Coherent perfect absorption (CPA)-the time-reversed operation of lasing at threshold-relies on finely tuned interference and is intrinsically fragile to disorder and structural imperfections. Whether absorption can be endowed with topological protection, by analogy to topological lasing, has remained an open question. Here, we experimentally demonstrate a topological antilaser: the time-reversed counterpart of a topological laser, in which...
Light-induced quantum friction of carbon nanotubes in water
Abstract Friction slows down moving objects at both macroscopic and microscopic scales1. At the electronic level, quantum friction describes direct transfer of momentum between a liquid and the electrons of a solid2. Owing to its microscopic nature, this phenomenon remains experimentally challenging to capture3.
Nanomagnets control diamond qubits, pointing to more scalable quantum hardware
Nanomagnets control diamond qubits, pointing to more scalable quantum hardware Gaby Clark Scientific Editor Robert Egan Associate Editor Quantum computing, once only a theoretical possibility, promises to deliver faster, more energy-efficient computers—but only if scientists can build and scale the hardware needed to run the machines. New research from Virginia Commonwealth University brings scientists one small step closer to quantum computing at a practical scale, which could help...
Policy on the AI Exponential
Policy on the AI Exponential In one of the side plots to The Lord of the Rings, two of the Hobbits attempt to rouse Treebeard—a wise but ponderous sentient tree—to defend his forest from an army that is cutting it down. The problem is that Treebeard operates at a very different speed than the Hobbits. It takes him a full day simply to say hello to another tree, so getting him and his peers to act fast enough is nearly impossible.
Suppressing the Motion of Rydberg Atoms in Inhomogeneous Electric Fields via Stark Echo
arXiv:2606.09759v1 Announce Type: new Abstract: Rydberg atoms possess strong electric dipole transitions and tunable energy levels, making them promising candidates for microwave to optical conversion on integrated superconducting atom chips. Achieving strong coupling of the atoms to e.g. the microwave field of an on-chip resonator requires placing the atoms within tens of micrometers from the chip surface. However, inhomogeneous stray electric fields originating from the surface can induce...
Optical Poling Reveals Hidden Molecular Restructuring in Multimode Fibers, Unlocking Ultra-Efficient Third-Order Nonlinearities
Announce Type: new Abstract: Optical poling is a well-established technique for inducing \chi^{(2)} nonlinearity, yet its impact on silica's molecular structure remains unexplored. Here, we report the first direct observation of molecular restructuring in large-core graded-index multimode fibers (MMFs) induced by optical poling, transforming the silica tetrahedral ring network. Through coherent light beating, this process converts large rings of more than four SiO_4 tetrahedra into smaller...
Light pulses uncover Higgs mode that reshapes perovskite crystal symmetry
Light pulses uncover Higgs mode that reshapes perovskite crystal symmetry Sadie Harley Scientific Editor Robert Egan Associate Editor Waves of light and sound interact to drive electronic and structural changes in a perovskite crystal. At the atomic scale, nothing is ever truly still. Materials that appear perfectly rigid and motionless to the naked eye are in fact swarms of vibrating atoms.
