Using CSST and ejecta-wind interaction in type II-P supernovae to constrain the wind-mass loss of red supergiant stars
The properties of H-rich, type II-plateau supernova (SN II-P) progenitors remain uncertain, and this is primarily due to the complexities associated with red supergiant (RSG) wind-mass loss. Recent studies have suggested that the interaction of the ejecta with a standard RSG wind should produce unambiguous signatures in the optical (e.g., a broad, boxy H$α$ profile) and in the UV (especially Ly $α$ and Mg ii $λλ$ 2795, 2802) a few years following the explosion. Such features are expected to…

Base-extension Semantics for S5 Modal Logic
We develop a proof-theoretic semantics -- in particular, a base-extension semantics -- for multi-agent S5 modal logic (and hence also for the usual unindexed S5). Following the inferentialist interpretation of logic, this gives us a semantics in which validity is based on proof rather than truth. In base-extension semantics, the validity of formulae is generated by provability in a `base' of atomic rules and an inductive definition of the validity of the connectives. Base-extension semantics fo…

On a generalization of R. Chapman's "evil determinant"
Let $p$ be an odd prime and $x$ be an indeterminate. Recently, Z.-W. Sun proposed the following conjecture: $$\det\left[x+\left(\frac{j-i}{p}\right)\right]_{0\le i,j\le \frac{p-1}{2}}=\begin{cases} (\frac{2}{p})pb_px-a_p & \mbox{if}\ p\equiv 1\pmod4, 1 & \mbox{if}\ p\equiv 3\pmod4, \end{cases}$$ where $a_p$ and $b_p$ are rational numbers related to the fundamental unit and class number of the real quadratic field $\mathbb{Q}(\sqrt{p})$. In this paper, we confirm the above conjecture of Sun base…

The Cowboys should sign CeeDee Lamb before Dak Prescott
As the calendar flips pages from May to June, the year 2024 seems to be flying by. The Dallas Cowboys and the rest of the NFL are in the middle of preparing for the new season. Veterans are getting back into the swing of things and rookies are getting acclimated to their new surroundings. Their 2024 draft class is in attendance and all accounted for but the same can't be said for their veterans. There are two impactful players who, so far, have decided not to join the team in OTAs. I know, Darr…

Quantum colored strings in the hole-doped $t$-$J_z$ model
The stripe phase, an intertwined order observed in high-temperature superconductors, is regarded as playing a key role in elucidating the underlying mechanism of superconductivity, especially in cuprates. Following Jan Zaanen's early scenario, the full-filled charge stripe can be taken as the interactive elastic quantum strings of holes, stabilized by $π$-phase shifts between neighboring magnetic domains. However, this scenario is challenging to explain, particularly in terms of electron pairi…

Smooth Surfaces via Nets of Geodesics
The goal of this study is to provide a method for computing the following: Given a network of curves in 3d (satisfying a condition at the intersection points), compute efficiently a smooth surface such that the curves are geodesics on it. This work can serve as a base for engineers who wish to implement computations of such surfaces in Computer Aided Design (CAD) software or other applications. The motivation for this study was the following hypothesis and observation together with the desire t…

Even-Odd Layer-Dependent Exchange Bias Effect in MnBi2Te4 Chern Insulator Devices
Magnetic topological materials with coexisting magnetism and non-trivial band structures exhibit many novel quantum phenomena, including the quantum anomalous Hall effect, the axion insulator state, and the Weyl semimetal phase. As a stoichiometric layered antiferromagnetic topological insulator, thin films of MnBi2Te4 show fascinating even-odd layer-dependent physics. In this work, we fabricate a series of thin-flake MnBi2Te4 devices using stencil masks and observe the Chern insulator state at…
