In 1967, physicist Andrei Sakharov proposed a set of conditions that must be satisfied to explain the origin of the matter-antimatter asymmetry in the universe,
including violation of the combined charge conjugation and parity (CP) symmetry.
CP symmetry was once thought to be universally conserved,
until this view was overturned in 1964 with the discovery of CP violation in the decay of neutral kaons.
This landmark result later earned the Nobel Prize in Physics in 1…
Photo in the fog that I took last week. I had hoped for more frost but - well. At least there was quite some #fog!
This spot is really interesting. I have there been only a few times now but it looks so very different each time I'm there.

Parallel Neuron Groups in the Drosophila Brain

Abstract: The full connectome of an adult Drosophila enables a search for novel neural structures in the insect brain. I describe a new neural structure, called a Parallel Neuron Group (PNG). Two neurons are called parallel if they share a significant number of input neurons and output neurons. Most pairs of neurons in the Drosophila brain have very small parallel match. There are about twenty larger groups of neurons for which any pair of neurons in the group has a high match. These are the parallel groups. Parallel groups contain only about 1000 out of the 65,000 neurons in the brain, and have distinctive properties. There are groups in the right mushroom bodies, the antennal lobes, the lobula, and in two central neuropils (GNG and EB). Most parallel groups do not have lateral symmetry. A group usually has one major input neuron, which inputs to all the neurons in the group, and a small number of major output neurons. The major input and output neurons are laterally asymmetric. Parallel neuron groups present puzzles, such as: what does a group do, that could not be done by one larger neuron? Do all neurons in a group fire in synchrony, or do they perform different functions? Why are they laterally asymmetric? These may merit further investigation.

A $5$-Approximation Analysis for the Cover Small Cuts Problem

Abstract: In the Cover Small Cuts problem, we are given a capacitated (undirected) graph $G=(V,E,u)$ and a threshold value $\lambda$, as well as a set of links $L$ with end-nodes in $V$ and a non-negative cost for each link $\ell\in L$; the goal is to find a minimum-cost set of links such that each non-trivial cut of capacity less than $\lambda$ is covered by a link. Bansal, Cheriyan, Grout, and Ibrahimpur (arXiv:2209.11209, Algorithmica 2024) showed that the WGMV primal-dual algorithm, due to Williamson, Goemans, Mihail, and Vazirani (Combinatorica, 1995), achieves approximation ratio $16$ for the Cover Small Cuts problem; their analysis uses the notion of a pliable family of sets that satisfies a combinatorial property. Later, Bansal (arXiv:2308.15714v2, IPCO 2025) and then Nutov (arXiv:2504.03910, MFCS 2025) proved that the same algorithm achieves approximation ratio $6$. We show that the same algorithm achieves approximation ratio $5$, by using a stronger notion, namely, a pliable family of sets that satisfies symmetry and structural submodularity.

Abstract: The precise manipulation and analysis of neutron spin states are foundational for a wide range of physics experiments, from fundamental symmetry tests to materials science. To enable systematic characterization of neutron polarimetry devices, we have constructed and extended a monochromatic neutron beamline at the Spallation Neutron Source, Oak Ridge National Laboratory. The beamline delivers monochromatic neutrons and provides a flexible platform for deploying and evaluating advanced neutron spin manipulation instruments. We describe the design and commissioning of the extended beamline and present a proof-of-concept neutron polarimetry study using three devices: a supermirror neutron polarizer, a Mezei spin flipper, and an in situ neutron 3He spin analyzer system. Performance metrics, optimization strategies, and systematic effects are discussed, demonstrating the beamline utility for neutron instrumentation testing. These results establish the extended monochromatic beamline as a useful resource for the development and validation of neutron polarimetry technologies.

Manipulation of photonic topological edge and corner states via trivial claddings

Abstract: Crystalline symmetry offers a powerful tool to realize photonic topological phases, in which additional trivial claddings are typically required to confine topological boundary states. However, the utility of the trivial cladding in manipulating topological waves is often overlooked. Here, we demonstrate two topologically distinct kagome photonic crystals (KPCs) based on different crystalline symmetries: \mathbit{C}_\mathbf{6}- symmetric KPCs exhibit a quantum spin Hall phase, while \mathbit{C}_\mathbf{3}-symmetric KPCs serve as trivial cladding. By tuning the geometric parameter of the trivial cladding, we observe that a pair of topological interface states featured with pseudospin-momentum locking undergoes a phase transition, accompanied by the appearance and disappearance of corner states in a finite hexagonal supercell. Such a geometry-induced band inversion is characterized by a sign change in the Dirac mass of the topological interface states and holds potential for applications such as rainbow trapping. Furthermore, we experimentally demonstrate the corner states, which is a hallmark of higher-order topology, also depend critically on the trivial cladding. Our work highlights the crucial role of trivial claddings on the formation of topological boundary states, and offers a novel approach for their manipulation.

Mesh of Spatiotemporal Optical Vortices with Programmable Intensity Nulls

Abstract: Light carrying transverse orbital angular momentum (T-OAM) in the form of spatiotemporal optical vortices (STOVs) is opening new degrees of freedom for structured light manipulation. Such spatiotemporal wavepackets hold significant potential for optical trapping, analog optical computing, studying photonic symmetry and topology, among others. Up to now, synthesizing of such vortices is limited in one dimension, either in temporal or spatial domain. In this work, we propose and experimentally demonstrate a two-dimensional flexible mesh of spatiotemporal optical vortices (M-STOV) with programmable intensity nulls, and analyze their diffraction patterns for detection. Furthermore, we extend the spectral range of M-STOV via second-harmonic generation while examining the transfer of OAM in this nonlinear process. This study establishes a foundational framework for designing higher dimensional spatiotemporal vortex fields and promises a high-capacity information carrier based on ST optical vortices.
