Structural and Optical Properties of Crystal Ion Sliced BaTiO$_3$ Thin Films
Barium titanate (BaTiO$_3$) is a compelling material for integrated photonics due to its strong electro-optic and second-order nonlinear properties. Crystal Ion Slicing (CIS) presents a scalable and CMOS-compatible route for fabricating thin BaTiO$_3$ films; however, ion implantation during CIS introduces lattice damage that can degrade structural and optical performance. In this study, we demonstrate that post-slicing thermal annealing effectively restores the structural integrity and optical …

Spin-lattice entanglement in $\mathbf{CoPS}_3$
Complex chalcogenides in the $M$PS$_3$ family of materials ($M$ = Mn, Fe, Co, and Ni) display remarkably different phase progressions depending upon the metal center orbital filling, character of the P-P linkage, and size of the van der Waals gap. There is also a stacking pattern and spin state difference between the lighter and heavier transition metal-containing systems that places CoPS$_3$ at the nexus of these activities. Despite these unique properties, this compound is under-explored. Her…

1/2 “My input stream is full of it: Fear and loathing and cheerleading and prognosticating on what generative AI means and whether it’s Good or Bad and what we should be doing. All the channels: Blogs and peer-reviewed papers and social-media posts and business-news stories. So there’s lots of AI angst out there, but this is mine. I think the following is a bit unique because it focuses on cost, working backward from there.”

NAM: A Normalization Attention Model for Personalized Product Search In Fliggy
Personalized product search provides significant benefits to e-commerce platforms by extracting more accurate user preferences from historical behaviors. Previous studies largely focused on the user factors when personalizing the search query, while ignoring the item perspective, which leads to the following two challenges that we summarize in this paper: First, previous approaches relying only on co-occurrence frequency tend to overestimate the conversion rates for popular items and underestim…

Hmmmm… here is a problem I did not anticipate.
Every time I empty the main pond hole of water, (the actual hole under the liner) water returns within an hour or two. I’ve done it 4 times now, and it keeps filling back up with water.
Obviously there is water underground infiltrating into the pond hole, and/or the water table itself is above the bottom of the hole. It is not coming from either of the other holes because they both have the same amount of water in them as they did this morning.
I have “watered” the blueberry patch and hazelnut tree a lot with the water that I have been cleaning the filter with… and we also had lots of water flying around outside the liners yesterday as I tested the pump. So it is quite possible that the ground around the pond is simply well saturated.
I think I am going to have to just keep removing the water (and putting it into the sewer) until it does not refill. We have a week of hot weather coming. Surely that will be enough time for everything to dry out completely.
Otherwise I might run into some issues if the rains return before I can anchor down the pond liner with gravel and get the plumbing in!
How is time already running short!?
Never underestimate the ability of water to find a place where it is not wanted. 😆

Integer-Clustering Optimization of Hydrogen and Battery EV Fleets Considering DERs
Electrified transportation leads to a tighter integration between transportation and energy distribution systems. In this work, we develop scalable optimization models to co-design hydrogen and battery electric vehicle (EV) fleets, distributed energy resources, and fast-charging and hydrogen-fueling infrastructure to efficiently meet transportation demands. A novel integer-clustering formulation is used for optimizing fleet-level EV operation while maintaining accurate individual vehicle dispat…

Lattice investigation of custodial two-Higgs-doublet model at weak quartic couplings
The $SU(2){-}$gauged custodial two-Higgs-doublet model, which shares the same global-symmetry properties with the standard model, is studied non-perturbatively on the lattice. The additional Higgs doublet enlarges the scalar spectrum and opens the possibility for spontaneous breaking of the global symmetry. In this work we start by showing the occurrence of spontaneous breaking of the custodial symmetry in a region of the parameter space of the model. Following this, both the spectrum and the r…

Triplet Exciton-driven Topological Mott insulator at Finite Temperature
Motivated by experiments in which the quantum anomalous Hall (QAH) charge gap greatly exceeds the Curie temperature, we apply determinantal quantum Monte Carlo to two complementary lattice models with different geometries: the checkerboard quantum-spin-Hall-Hubbard model and the generalized Kane-Mele-Hubbard model. In both cases an incompressible QAH phase with total Chern number $C=\pm 1$ emerges at quarter filling well above the Curie temperature. Each spin channel carries its own nonquantize…
