Finite spin-glass transition of the $\pm J$ XY model in three dimensions

open access: yes, 2004
A three-dimensional $\pm J$ XY spin-glass model is investigated by a nonequilibrium relaxation method. We have introduced a new criterion for the finite-time scaling analysis. A transition temperature is obtained by a crossing point of obtained data. The

Ensemble Inequivalence and the Spin-Glass Transition [PDF]

open access: yes, 2011
We report on the ensemble inequivalence in a many-body spin-glass model with integer spin. The spin-glass phase transition is of first order for certain values of the crystal field strength and is dependent whether it was derived in the microcanonical or

Age‐Related Changes in Myeloid Cells and Their Impact on Subcutaneous Melanoma Growth in Mice

open access: yesAging and Cancer, EarlyView.
Our findings reveal that age‐related changes in subcutaneous melanoma growth and immunotherapy response are context‐dependent. In models where tumor growth and treatment resistance increase with age, this effect is partly driven by enhanced immunosuppression from myeloperoxidase‐active Gr‐1⁺ myeloid cells.

Using the critical behavior in Zn1−xMnxTe to probe the relationship between quasi-two-dimensional and three-dimensional spin-glasses

open access: yesAIP Advances
Single-crystalline Zn1−xMnxTe is a three-dimensional (3D) monochalcogenide system that exhibits a prominent spin-glass transition at low-temperatures. This system is based on the host ZnTe semiconductor where Mn goes into the lattice substitutionally at ...

The upper limit of the in-plane spin splitting of Gaussian beam reflected from a glass-air interface

open access: yesScientific Reports, 2017
Optical spin splitting has a promising prospect in quantum information and precision metrology. Since it is typically small, many efforts have been devoted to its enhancement.

The Immobilization of Hyaluronic Acid in 3D Hydrogel Scaffolds Modulates Macrophage Polarization

open access: yesAdvanced Biology, EarlyView.
This study explores the use of collagen‐hyaluronic acid (HA) hydrogels for the 3D culture of macrophages, providing a useful tool for modelling macrophage behavior in tissues and diseases. It highlights how hydrogel composition, mechanical properties, and preparation methods influence macrophage behavior, revealing for the first time that HA's ...

Atom-by-atom construction of attractors in a tunable finite size spin array

open access: yesNew Journal of Physics, 2020
We demonstrate that a two-dimensional finite and periodic array of Ising spins coupled via RKKY-like exchange can exhibit tunable magnetic states ranging across three distinct magnetic regimes: (1) a conventional ferromagnetic regime, (2) a glass-like ...

Absence of Phase Stiffness in the Quantum Rotor Phase Glass

open access: yes, 2003
We analyze here the consequence of local rotational-symmetry breaking in the quantum spin (or phase) glass state of the quantum random rotor model. By coupling the spin glass order parameter directly to a vector potential, we are able to compute whether ...

Dynamical AC study of the critical behavior in Heisenberg spin glasses [PDF]

open access: yes, 2004
We present some numerical results for the Heisenberg spin-glass model with Gaussian interactions, in a three dimensional cubic lattice. We measure the AC susceptibility as a function of temperature and determine an apparent finite temperature transition ...

Using a Supramolecular Approach to Engineer Modular Hydrogel Platforms for Culturing Protoplasts – from General Tissue Engineering to Cellular Agriculture

open access: yesAdvanced Biology, EarlyView.
Using supramolecular monomers, various hydrogel culture systems were formulated to culture protoplasts; including 2D, 2.5D, and 3D hydrogels. Depending on the culture platform, bioactive functionalization led to protoplast enlargement (2D and 2.5D) or plasmolysis (3D). This work shows the potential to modularly engineer synthetic platforms for cellular
