Pathology of Schwinger boson mean field theory for Heisenberg spin models [PDF]

, 2002
We have re-analyze the Schwinger boson mean field theory (SBMFT) for Heisenberg spin models on the cubic lattice. We find that the second order phase transition point for magnetic ordering previously reported corresponds to a local maximum of the free ...

Noncommutative generalizations of theorems of Cohen and Kaplansky [PDF]

, 2011
This paper investigates situations where a property of a ring can be tested on a set of "prime right ideals." Generalizing theorems of Cohen and Kaplansky, we show that every right ideal of a ring is finitely generated (resp.

Some identities for enumerators of circulant graphs

, 2001
We establish analytically several new identities connecting enumerators of different types of circulant graphs of prime, twice prime and prime-squared orders.

THE CHEMICAL TOPOLOGICAL GRAPH ASSOCIATED WITH THE NILPOTENT GRAPH OF A MODULO RING OF PRIME POWER ORDER

Journal of Fundamental Mathematics and Applications (JFMA)
Chemical topological graph theory constitutes a subdomain within mathematical chemistry that leverages graph theory to model chemical molecules.  In this context, a chemical graph serves as a graphical representation of molecular structures. Specifically,

Hyperon Nonleptonic Weak Decays Revisited

, 2000
We first review the current algebra - PCAC approach to nonleptonic octet baryon 14 weak decay B (\to) (B^{\prime})(\pi) amplitudes. The needed four parameters are independently determined by (\Omega \to \Xi \pi),(\Lambda K) and (\Xi ^{-}\to \Sigma ...

The Open String Regge Trajectory and Its Field Theory Limit [PDF]

, 2011
We study the properties of the leading Regge trajectory in open string theory including the open string planar one-loop corrections. With SU(N) Chan-Paton factors, the sum over planar open string multi-loop diagrams describes the 't Hooft limit N\to ...

Symmetric chain decomposition for cyclic quotients of Boolean algebras and relation to cyclic crystals

, 2011
The quotient of a Boolean algebra by a cyclic group is proven to have a symmetric chain decomposition. This generalizes earlier work of Griggs, Killian and Savage on the case of prime order, giving an explicit construction for any order, prime or ...

Primordial black holes as a probe of strongly first-order electroweak phase transition [PDF]

, 2021
Primordial black holes can be produced by density fluctuations generated from delayed vacuum decays of first-order phase transition. The primordial black holes generated at the electroweak phase transition have masses of about 10 − 5 solar mass.
