A New Quasi‐Solid Polymer Electrolyte for Next‐Generation Na–O2 Batteries: Unveiling the Potential of a Polyamide‐Polyether System

Advanced Science, EarlyView.
This study introduces a novel, sustainable Pebax1657‐based quasi‐solid polymer electrolyte (QSPE) that enhances the performance and safety of sodium–oxygen (Na–O2) batteries. The developed QSPE shows improved Na+ ion transport, reduced overpotentials, and better cycling stability compared to the conventional liquid systems, highlighting its potential ...

Degenerate manifolds, helimagnets, and multi-Q chiral phases in the classical Heisenberg antiferromagnet on the face-centered-cubic lattice

Physical Review Research, 2020
We present a detailed study of the ground-state phase diagram of the classical frustrated Heisenberg model on the face-centered-cubic lattice. By considering exchange interactions to third nearest neighbors, we find commensurate, helimagnetic, as well as

Commensurate-incommensurate transition in the chiral Ashkin-Teller model

Physical Review Research, 2022
We investigate the classical chiral Ashkin-Teller model on a square lattice with the corner transfer matrix renormalization group algorithm. We show that the melting of the period-4 phase in the presence of a chiral perturbation takes different forms ...

Azbel-Hofstadter model on triangular lattice revisited

, 2001
In the present paper, the mean of Lyapunov exponents for the Azbel-Hofstadter model on the triangular lattice is calculated. It is recently proposed that [Phys. Rev. Lett.

Direct Observation of Suppressed Optical–Acoustic Phonon Energy Coupling in Supported SWCNT at Cryogenic Temperatures

Advanced Science, EarlyView.
This study quantifies the temperature‐dependent optical–acoustic phonon coupling factor (GOA) in supported single‐walled carbon nanotubes, revealing significant suppression at low temperatures. At high temperatures, GOA increases monotonically and is attributed to intensified anharmonic phonon interactions. This research offers key insights into phonon

Frustrations and phase transitions in the Ising model on square lattice

Journal of Physics: Conference Series, 2014
The phase transitions in two-dimensional antiferromagnetic Ising model are studied on a square lattice by taking the interactions of next-nearest neighbors into account. The model is investigated on basis of the replica Monte Carlo algorithm and the histogrammic analysis of data.

Decorating Random Quadrangulations

, 2001
On various regular lattices (simple cubic, body centred cubic..) decorating an edge with an Ising spin coupled by bonds of strength L to the original vertex spins and competing with a direct anti-ferromagnetic bond of strength alpha L can give rise to ...

The Quest for the Quark‐Gluon Plasma From the Perspective of Dynamical Models of Relativistic Heavy‐Ion Collisions

Astronomische Nachrichten, EarlyView.
ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

Phase Transition of the Ising Model on Fractal Lattice

, 2015
Phase transition of the Ising model is investigated on a planar lattice that has a fractal structure. On the lattice, the number of bonds that cross the border of a finite area is doubled when the linear size of the area is extended by a factor of four ...
