I mean, there's a reason the switch for "I have guests over, let's turn off the most surprising automations" is called "haunted house" in my HomeAssistant.

Tuning chiral anomaly signature in a Dirac semimetal via fast-ion implantation
Cd$_3$As$_2$ is a prototypical Dirac semimetal that hosts a chiral anomaly and thereby functions as a platform to test high-energy physics hypotheses and to realize energy efficient applications. Here we use a combination of accelerator-based fast ion implantation and theory-driven planning to enhance the negative longitudinal magnetoresistance (NLMR)--a signature of a chiral anomaly--in Nb-doped Cd$_3$As$_2$ thin films. High-energy ion implantation is commonly used to investigate semiconductor…

Non-equilibrium state during proton-deuteron exchange at a liquid-liquid interface
The exchange of protons and deuterons is a very fast process, even on macroscopic length scales. Here we directly measure quantitatively the formation of HDO within the first 100 microseconds of the reaction at the liquid-liquid interface between D$_2$O and H$_2$O using a fast-flowing liquid flat jet and infrared spectroscopic imaging. During early stages of the reaction, the rate of HDO formation is limited by the availability of hydroxide and hydronium ions mediating the reaction, rather than…

Beyond Copenhagen: Following the Trail of Decoherence in Feynman's Light Microscope
Feynman's light microscope invites us to reconsider what we thought we knew about quantum reality. Rather than invoking wavefunction collapse to predict the loss of fringes in a monitored interferometer, Feynman analyzes the problem in terms of a disturbance. This approach raises the question of whether the classical world, including its localized particles and definite measurement outcomes, might emerge as the universe evolves smoothly according to ß. Treating the particle and its environment…

Distribution Testing in the Presence of Arbitrarily Dominant Noise with Verification Queries
We study distribution testing without direct access to a source of relevant data, but rather to one where only a tiny fraction is relevant. To enable this, we introduce the following verification query model. The goal is to perform a statistical task on distribution $\boldsymbol{p}$ given sample access to a mixture $\boldsymbol{r} = λ\boldsymbol{p} + (1-λ)\boldsymbol{q}$ and the ability to query whether a sample was generated by $\boldsymbol{p}$ or by $\boldsymbol{q}$. In general, if $m_0$ sa…

Atomically thin silver films for enhanced nanoscale nonlinear optics
The inherently weak nonlinear optical response of bulk materials remains a fundamental limitation in advancing photonic technologies. Nanophotonics addresses this challenge by tailoring the size and morphology of nanostructures to manipulate the optical near field, thus modulating the nonlinear response. Here, we explore a complementary strategy based on engineering the electronic band structure in the mesoscopic regime to enhance optical nonlinearities. Specifically, we demonstrate an increase…
