Direct observation of distinct bulk and edge nonequilibrium spin accumulation in ultrathin MoTe$_2$
Low-symmetry two-dimensional (2D) topological materials such as MoTe$_2$ host efficient charge-to-spin conversion (CSC) mechanisms that can be harnessed for novel electronic and spintronic devices. However, the nature of the various CSC mechanisms and their correlation with underlying crystal symmetries remain unsettled. In this work, we use local spin-sensitive electrochemical potential measurements to directly probe the spatially dependent nonequilibrium spin accumulation in MoTe$_2$ flakes d…

Partial Differentiation of Callisto as Possible Evidence for Pebble Accretion
"Planetesimal or pebble" is one of the most fundamental open questions in planet formation theory. Similarly, "satellitesimal or pebble" remains unsettled regarding the formation of the Galilean satellites. I focus on a unique characteristic of Callisto--its interior is estimated to be only partially differentiated based on gravitational field measurements. I robustly demonstrate that such a state is not achievable through satellitesimal accretion, which inevitably leads to significant differen…

On the same day a military parade unfolds in D.C. to mark the Army’s 250th anniversary on Saturday,
an organized day of protests against the policies of President Donald Trump’s administration is planned for more than 2,000 cities nationwide.

While thunderstorms could disrupt the celebrations in D.C.,
weather will vary at locations around the country where rallies are planned.

Mostly dry and hot weather will dominate the western United States,
while it should b…

A Countable, Dense, Dedekind-Complete Subset of $\mathbb{R}$ Constructed by Extending $\mathbb{Q}$ via Simultaneous Marking of Closed Intervals with Rational Endpoints
This article explores the model-dependent nature of set cardinality, emphasizing that cardinality is not absolute but varies across different axiomatic frameworks. Although Cantor's diagonal argument shows the real numbers are non-denumerable within ZF (Zermelo-Fraenkel set theory), the precise cardinality of the continuum remains unsettled and depends critically on model assumptions. For instance, under Gödel's inner-model axiom V=Ultimate L, the Continuum Hypothesis (CH) holds, whereas Marti…
