Theory of Bubble Nucleation and Cooperativity in DNA Melting
S. Ares, N. K. Voulgarakis, K. O. Rasmussen +1
The onset of intermediate states (denaturation bubbles) and their role during the melting transition of DNA are studied using the Peyrard-Bishop-Daxuois model by Monte Carlo simula…
Covariance for Conic and Wedge Complete Filling
C. Rascon, A. O. Parry
Interfacial phenomena associated with fluid adsorption in two dimensional systems has recently been shown to exhibit hidden symmetries, or covariances, which precisely relate local…
Asymptotics of Regulated Field Commutators for Einstein-Rosen Waves
J. Fernando Barbero G., Guillermo A. Mena Marugán, Eduardo J. S. Villaseñor
We discuss the asymptotic behavior of regulated field commutators for linearly polarized, cylindrically symmetric gravitational waves and the mathematical techniques needed for thi…
Igniting homogeneous nucleation
J. C. Neu, L. L. Bonilla, A. Carpio
Transient homogeneous nucleation is studied in the limit of large critical sizes. Starting from pure monomers, three eras of transient nucleation are characterized in the classic B…
Theory of charge fluctuations and domain relocation times in semiconductor superlattices
L. L. Bonilla
Shot noise affects differently the nonlinear electron transport in semiconductor superlattices depending on the strength of the coupling among the superlattice quantum wells. Stron…
Effect of particle geometry on phase transitions in two-dimensional liquid crystals
Yuri Martinez-Raton, Enrique Velasco, Luis Mederos
Using a version of density-functional theory which combines Onsager approximation and fundamental-measure theory for spatially nonuniform phases, we have studied the phase diagram…
Length scale competition in soliton bearing equations: A collective coordinate approach
Sara Cuenda, Angel Sanchez
We study the phenomenon of length scale competition, an instability of solitons and other coherent structures that takes place when their size is of the same order of some characte…
Ratchet behavior in nonlinear Klein-Gordon systems with point-like inhomogeneities
Luis Morales-Molina, Franz G. Mertens, Angel Sanchez
We investigate the ratchet dynamics of nonlinear Klein-Gordon kinks in a periodic, asymmetric lattice of point-like inhomogeneities. We explain the underlying rectification mechani…
Interactions, disorder and local defects in graphite
M. A. H. Vozmediano, F. Guinea, M. P. Lopez-Sancho
Recent experiments report the existence of ferromagnetic and superconducting fluctuations in graphite at unexpectedly high temperatures. The interplay of disorder and interactions…
Postnikov pieces and BZ/p-homotopy theory
Natalia Castellana, Juan A. Crespo, Jerome Scherer
We present a constructive method to compute the cellularization with respect to K(Z/p, m) for any integer m > 0 of a large class of H-spaces, namely all those which have a finite n…
Theoretical approach to micro wave radiation-induced zero-resistance states in 2D electron systems
Jesus Inarrea, Gloria Platero
We present a theoretical model in which the existence of radiation-induced zero-resistance states is analyzed. An exact solution for the harmonic oscillator wave function in the pr…
Nonlinear excitations in DNA: Aperiodic models vs actual genome sequences
Sara Cuenda, Angel Sanchez
We study the effects of the sequence on the propagation of nonlinear excitations in simple models of DNA in which we incorporate actual DNA sequences obtained from human genome dat…
Many body effects on - axis properties: out of plane coherence and bilayer splitting
F. Guinea, M. P. Lopez-Sancho, M. A. H. Vozmediano
The out-of-plane hopping in layered metals with strong electronic correlation is analyzed theoretically. By studying the effects of in-plane interactions on the interlayer tunnelli…
Influence of Collision Cascade Statistics on Pattern Formation of Ion-Sputtered Surfaces
M. Feix, A. K. Hartmann, R. Kree +2
Theoretical continuum models that describe the formation of patterns on surfaces of targets undergoing ion-beam sputtering, are based on Sigmund's formula, which describes the spat…
Transfer Matrices and Partition-Function Zeros for Antiferromagnetic Potts Models. IV. Chromatic polynomial with cyclic boundary conditions
Jesper Lykke Jacobsen, Jesus Salas
We study the chromatic polynomial P_G(q) for m \times n square- and triangular-lattice strips of widths 2\leq m \leq 8 with cyclic boundary conditions. This polynomial gives the ze…
Particles and vacuum for perturbative and non-perturbative Einstein-Rosen gravity
J. Fernando Barbero G., Guillermo A. Mena Marugan, Eduardo J. S. Villaseñor
We discuss the connection between the Fock space introduced by Ashtekar and Pierri for Einstein-Rosen waves and its perturbative counterpart based on the concept of particle that a…
Equilibrium roughening transition in a 1D modified sine-Gordon model
Saul Ares, Angel Sanchez
We present a modified version of the one-dimensional sine-Gordon that exhibits a thermodynamic, roughening phase transition, in analogy with the 2D usual sine-Gordon model. The mod…
Asymptotic Analysis of Field Commutators for Einstein-Rosen Gravitational Waves
J. Fernando Barbero G., Guillermo A. Mena Marugán, Eduardo J. S. Villaseñor
We give a detailed study of the asymptotic behavior of field commutators for linearly polarized, cylindrically symmetric gravitational waves in different physically relevant regime…
A Generalization of Chetaev's Principle for a Class of Higher Order Non-holonomic Constraints
Hernan Cendra, Alberto Ibort, Manuel de Leon +1
The constraint distribution in non-holonomic mechanics has a double role. On one hand, it is a kinematic constraint, that is, it is a restriction on the motion itself. On the other…
Deconstructing Hopf spaces
Natalia Castellana, Juan A. Crespo, Jerome Scherer
We characterize Hopf spaces with finitely generated cohomology as an algebra over the Steenrod algebra. We "deconstruct" the original space into an H-space Y with finite mod p coho…
Numerical schemes for continuum models of reaction-diffusion systems subject to internal noise
Esteban Moro
We present new numerical schemes to integrate stochastic partial differential equations which describe the spatio-temporal dynamics of reaction-diffusion (RD) problems under the ef…
Global Theory of Quantum Boundary Conditions and Topology Change
M. Asorey, A. Ibort, G. Marmo
We analyze the global theory of boundary conditions for a constrained quantum system with classical configuration space a compact Riemannian manifold with regular boundary $Γ=\…
Altruism may arise from individual selection
Angel Sanchez, Jose A. Cuesta
The fact that humans cooperate with non-kin in large groups, or with people they will never meet again, is a long-standing evolutionary puzzle with profound implications. Cooperati…
Disorder and fluctuations in nonlinear excitations in DNA
Sara Cuenda, Angel Sanchez
We study the effects of the sequence on the propagation of nonlinear excitations in simple models of DNA, and how those effects are modified by noise. Starting from previous result…
