Solution of an associating lattice gas model with density anomaly on a Husimi lattice
T. J. Oliveira, J. F. Stilck, M. A. A. Barbosa
We study a model of a lattice gas with orientational degrees of freedom which resemble the formation of hydrogen bonds between the molecules. In this model, which is the simplified…
Universal Bounds for Eigenvalues of the Polyharmonic Operators
Jürgen Jost, Xianqing Li-Jost, Qiaoling Wang +1
We study eigenvalues of polyharmonic operators on compact Riemannian manifolds with boundary (possibly empty). In particular, we prove a universal inequality for the eigenvalues of…
Universal Inequalities for Eigenvalues of the Buckling Problem of Arbitrary Order
Jürgen Jost, Xianqing Li-Jost, Qiaoling Wang +1
We investigate the eigenvalues of the buckling problem of arbitrary order on compact domains in Euclidean spaces and spheres. We obtain universal bounds for the th eigenvalue in…
An Euler-type formula for and closed-form expressions for a class of zeta series
F. M. S. Lima
In a recent work, Dancs and He found an Euler-type formula for , being a positive integer, which contains a series they could not reduce to a finite closed-f…
Thermal Effects on the Stability of Excited Atoms in Cavities
F. C. Khanna, A. P. C. Malbouisson, J. M. C. Malbouisson +1
An atom, coupled linearly to an environment, is considered in a harmonic approximation in thermal equilibrium inside a cavity. The environment is modeled by an infinite set of harm…
Finite-size effects on the chiral phase diagram of four-fermion models in four dimensions
L. M. Abreu, A. P. C. Malbouisson, J. M. C. Malbouisson +1
We study the size dependence of the dynamical symmetry breaking in the four-dimensional Nambu-Jona-Lasinio model. We show that the presence of boundaries reduces the chiral breakin…
