Phase-Space Contractions of Carrollian Black-Hole Thermodynamics

Yingnan Xu, Shuangshuang Chu ยท 2026

We study Carrollian limits of Schwarzschild-AdS black-hole thermodynamics using covariant phase space. Allowing the cosmological constant to vary, we derive the extended Iyer-Wald identity and identifโ€ฆ

Absence of Quasi-Majorana False Positives in Full-Shell Hybrid Nanowires

Carlos Paya, Cesar Robles, Pablo San-Jose, Elsa Prada ยท 2026

Tunneling spectroscopy cannot be used as an unambiguous detection tool for Majorana zero modes (MZMs) in conventional partial-shell nanowires. The presence of smooth confinement at the end of the hybrโ€ฆ

Stationary solutions in the small-$c$ expansion of GR

Enes Bal, Ertugrul Ekiz, Emre Onur Kahya, Utku Zorba ยท 2026

We study the small-$c$ expansion of general relativity in ADM variables up to next-to-next-to-leading order (NNLO). We show that, in the stationary sector, this formulation renders the field equationsโ€ฆ

Unconstrained and Ropelength-Windowed $p$-densities of Knot Types

Makoto Ozawa ยท 2026

We study a family of scale-invariant $p$-densities of knot types in $R^3$, defined as the ratio of length to an $L^p$-type spread of pairwise distances along a curve. The first point of the paper is tโ€ฆ

Which Small-Sample Correction Should Be Used When Analyzing Stepped-Wedge Designs with Time-Varying Treatment Effects?

Yongdong Ouyang, Monica Taljaard, James P. Hughes, Fan Li ยท 2026

Stepped-wedge cluster randomized trials (SW-CRTs) evaluate interventions rolled out across clusters over time. Standard analyses typically use immediate-treatment (IT) models, which assume effects begโ€ฆ

Statistical Signatures of Majorana Zero Modes in Disordered Topological Superconductor Antidot Vortices

Zhibo Ren, Jukka I. Vayrynen ยท 2026

An antidot-pinned vortex in a three-dimensional topological insulator-superconductor platform hosts a Majorana zero mode (MZM). However, numerous Caroli-de Gennes-Matricon (CdGM) states coexist with iโ€ฆ

A Practical Guide to Interpret a Randomized Controlled Trial

Ibrahim Halil Tanboga ยท 2026

The most dangerous error in clinical trial interpretation is equating p > 0.05 with no effect. This review provides a practical, algorithm-based framework for classifying randomized controlled trial (โ€ฆ
