Applying the Effective Bond Energy Formalism (EBEF) to Describe the Sigma (σ) Phase in the Co-Cr-Ni-Re System
Proper descriptions of Topologically Closed-Packed (TCP) phases in thermodynamic databases are essential to adequately design new alloys. Thus, the...

Tropological sigma models
With the use of mathematical techniques of tropical geometry, it was shown by Mikhalkin some twenty years ago that certain Gromov-Witten invariants...

Fractional particle and sigma model
We introduce a classical fractional particle model in ℝ n , extending the Newtonian particle concept with the incorporation of the fractional...

Phase transitions in the logarithmic Maxwell O(3)-sigma model
We investigate the presence of topological structures and multiple phase transitions in the O(3)-sigma model with the gauge field governed by...

Peculiarities of beta functions in sigma models
In this paper we consider perturbation theory in generic two-dimensional sigma models in the so-called first-order formalism, using the coordinate...

Moduli spaces of instantons in flag manifold sigma models. Vortices in quiver gauge theories
In this paper, we discuss lumps (sigma model instantons) in flag manifold sigma models. In particular, we focus on the moduli space of BPS lumps in...

Haloperidol, a Sigma-1 Receptor Antagonist, Inhibits Ca2+ Responses in Rat Peritoneal Macrophages
AbstractSigma-1 receptors are ubiquitous multifunctional ligand-regulated molecular chaperons in the membrane of the endoplasmic reticulum, having a...

Space-like electromagnetic form factors of lambda- and sigma-baryons from quark-diquark Faddeev equations
An important goal of ongoing and future experiments is to explore spectra and transition form factors of baryons with non-zero strangeness. Of...

Entanglement and Rényi entropies of (1+1)-dimensional O(3) nonlinear sigma model with tensor renormalization group
We investigate the entanglement and Rényi entropies for the (1+1)-dimensional O(3) nonlinear sigma model using the tensor renormalization group...

Experimental Study of a Prototype of a Superconducting Sigma Neuron for Adiabatic Neural Networks
AbstractThe artificial neuron proposed earlier for use in superconducting neural networks is experimentally studied. The fabricated sample is a...

Joule–Thomson expansion and images of black hole in SU(N)-non-linear sigma model
We consider recently constructed black holes in the Einstein SU(N)-non-linear sigma model and study the Joule–Thomson expansion and observable...

The BV action of 3D twisted R-Poisson sigma models
We determine the solution to the classical master equation for a 3D topological field theory with Wess-Zumino term and an underlying geometrical...

The Chiral Medium in a Generalized Sigma Model and the Chiral Perturbation Theory
Abstract —The possibility of the formation of a phase with local parity violation(LPV) in a chiral medium in central collisions of heavy ions at high...

Sigma models as Gross–Neveu models
AbstractWe review the correspondence between integrable sigma models with complex homogeneous target spaces and the chiral bosonic (and possibly...

Phase Space Representation
Here we introduce the phase space representation of many-body quantum systems. We consider specifically Gaussian states and their characteristic...

Dynamical Stability Phase Transitions
We present an in-depth analysis of the dynamical stability phase diagrams of QBHs. The first key observation is that boundaries separating...

Dimensional reduction of Courant sigma models and Lie theory of Poisson groupoids
We show that the 2d Poisson Sigma Model on a Poisson groupoid arises as an effective theory of the 3d Courant Sigma Model associated with the double...

Non-Abelian T-dualities in two dimensional (0, 2) gauged linear sigma models
We consider two dimensional (2D) gauged linear sigma models (GLSMs) with (0, 2) supersymmetry and U(1) gauge group which posses global symmetries. We...
