Steklov Spectral Uniqueness of Geodesic Balls in 3-Dimensional Space Forms via Guillemin--Wodzicki Residues

Zuoqin Wang, Hanzhang Yun

Let be the Dirichlet-to-Neumann operator on the boundary of a compact three-dimensional Riemannian manifold. Using the Lee--Uhlmann full-symbol formula and Weyl's invariant the…

Activity and Competing Length Scales in an Anomalous Core-Softened Fluid

Davi Felipe Kray Silva, Thiago Puccinelli, Walas Silva-Oliveira +2

The interplay between activity and competing interaction length scales remains largely unexplored, despite its relevance to many soft and biological systems. Here, we study Active…

Amorphous Radial Frustration and Water-Like Anomalies in a Ramp-Shoulder Fluid

Murilo S. Marques, Lucas Axel R. Santana, Gabriel San R. R. Câmara +1

We investigate the thermodynamic, structural, and dynamic behavior of a three-dimensional coarse-grained ramp-shoulder fluid derived from effective interactions between polymer-gra…

Confinement-controlled chase-escape dynamics

R. G. Rossatto, H. Ariel Alvarez, C. Manuel Carlevaro +1

We investigate a minimal chase-and-escape model on a two-dimensional square lattice with randomly distributed static obstacles, focusing on how geometric disorder controls collecti…

Order-Disorder Transitions and Thermal Pathways in Frustrated 2D Colloidal Crystals

Alexandre Vargas, Thiago Puccinelli, José Rafael Bordin

We employ extensive NPT molecular dynamics simulations to explore the thermal transitions of two-dimensional colloidal crystals interacting via a core-softened potential with compe…

How Soft is Too Soft? Tuning Order and Disorder in Dimeric Core-Soft Colloids with Bond Flexibility

Leandro B. Krott, Davi Felipe Kray Silva, A. de J. Ríos-Roldan +3

We employ molecular dynamics simulations to explore how internal flexibility affects phase transitions in soft-matter systems composed of dimers interacting via a core-softened pot…
