Symmetry-adapted formulation of the combined G-particle-hole Hypervirial equation and Hermitian Operator method
Diego R. Alcoba, Gustavo E. Massaccesi, Ofelia B. Oña +3
High accuracy energies of low-lying excited states, in molecular systems, have been determined by means of a procedure which combines the G-particle-hole Hypervirial (GHV) equation…
Additive consistency of risk measures and its application to risk-averse routing in networks
Roberto Cominetti, Alfredo Torrico
This paper investigates the use of risk measures and theories of choice for modeling risk-averse route choice and traffic network equilibrium with random travel times. We interpret…
Planning the electron traffic in semiconductor networks: A mesoscopic analog of the Braess paradox encountered in road networks
S. Huant, S. Baltazar, P. Liu +7
By combining quantum simulations of electron transport and scanning-gate microscopy, we have shown that the current transmitted through a semiconductor two-path rectangular network…
Nonlinear supersymmetry in the quantum Calogero model
Francisco Correa, Olaf Lechtenfeld, Mikhail Plyushchay
It is long known that the rational Calogero model describing n identical particles on a line with inverse-square mutual interaction potential is quantum superintegrable. We review…
Meron-cluster simulation of the quantum antiferromagnetic Heisenberg model in a magnetic field in one- and two-dimensions
G. Palma, A. Riveros
Motivated by the numerical simulation of systems which display quantum phase transitions, we present a novel application of the meron-cluster algorithm to simulate the quantum anti…
On the ergodic theory of free group actions by real-analytic circle diffeomorphisms
Bertrand Deroin, Victor Kleptsyn, Andrés Navas
We consider finitely generated groups of real-analytic circle diffeomorphisms. We show that if such a group admits an exceptional minimal set (i.e., a minimal invariant Cantor set)…
Self-generated interior blow-up solutions in fractional elliptic equation with absorption
Huyuan Chen, Patricio Felmer, Alexander Quaas
In this paper we study positive solutions to problem involving the fractional Laplacian , subject to the conditions…
The size of quadratic -adic linearization disks
Karl-Olof Lindahl
We find the exact radius of linearization disks at indifferent fixed points of quadratic maps in . We also show that the radius is invariant under power series pertur…
Particle in a self-dual dyon background: hidden free nature, and exotic superconformal symmetry
Mikhail S. Plyushchay, Andreas Wipf
We show that a non-relativistic particle in a combined field of a magnetic monopole and 1/r^2 potential reveals a hidden, partially free dynamics when the strength of the central p…
The Boulware-Deser mode in Zwei-Dreibein gravity
Máximo Bañados, Cedric Deffayet, Miguel Pino
Massive gravity in three dimensions accepts several different formulations. Recently, the 3-dimensional bigravity dRGT model in first order form, Zwei-Dreibein gravity, was conside…
Infinitely many positive solutions of nonlinear Schrödinger equations with non-symmetric potentials
Manuel del Pino, Juncheng Wei, Wei Yao
We consider the standing-wave problem for a nonlinear Schrödinger equation, corresponding to the semilinear elliptic problem \begin{equation*} -Δu+V(x)u=|u|^{p-1}u,\ u\in H^1(\math…
Chaos and Unpredictability in Evolution
Iaroslav Ispolatov, Michael Doebeli
The possibility of complicated dynamic behaviour driven by non-linear feedbacks in dynamical systems has revolutionized science in the latter part of the last century. Yet despite…
Zahir: a Object-Oriented Framework for Computer Graphics
Eduardo Graells-Garrido, María Cecilia Rivara
In this article we present Zahir, a framework for experimentation in Computer Graphics that provides a group of object-oriented base components that take care of common tasks in re…
A model for the self-organization of vesicular flux and protein distributions in the Golgi apparatus
Iaroslav Ispolatov, Anne Muesch
The generation of two non-identical membrane compartments via exchange of vesicles is considered to require two types of vesicles specified by distinct cytosolic coats that selecti…
Cosmic Neutrino Background as a Ferromagnet
Paola Arias, Jorge Gamboa, Justo Lopez-Sarrion
If cosmic background neutrinos interact very weakly with each other, through spin-spin interactions, then they may have experienced a phase transition, leading to a ferromagnetic o…
Fermion in a multi-kink-antikink soliton background, and exotic supersymmetry
Adrian Arancibia, Juan Mateos Guilarte, Mikhail S. Plyushchay
We construct a fermion system in a multi-kink-antikink soliton background, and present in an explicit form all its trapped configurations (bound state solutions) as well as scatter…
DGP Cosmological model with generalized Ricci dark energy
Yeremy Aguilera, Arturo Avelino, Norman Cruz +2
The braneworld model proposed by Dvali, Gabadadze and Porrati (DGP) leads to an accelerated universe without cosmological constant or other form of dark energy for the positive bra…
On the variational structure of breather solutions
Miguel A. Alejo, Claudio Muñoz, José M. Palacios
In this paper we give a systematic and simple account that put in evidence that many breather solutions of integrable equations satisfy suitable variational elliptic equations, whi…
On the long time behavior of stochastic vortices systems
Joaquin Fontbona, Benjamin Jourdain
In this paper, we are interested in the long-time behaviour of stochastic systems of n interacting vortices: the position in R2 of each vortex evolves according to a Brownian motio…
Comparison of the Mechanical Properties of Self-Assembled Langmuir Monolayers of Nanoparticles and Phospholipids
Siheng Sean You, Rossen Rashkov, Pongsakorn Kanjanaboos +4
Nanoparticles with hydrophobic capping ligands and amphiphilic phospholipids are both found to self-assemble into monolayer films when deposited on the air water interface. By sepa…
Asymptotically flat spacetimes in three-dimensional higher spin gravity
Hernan A. Gonzalez, Javier Matulich, Miguel Pino +1
A consistent set of asymptotic conditions for higher spin gravity in three dimensions is proposed in the case of vanishing cosmological constant. The asymptotic symmetries are foun…

E. R. P. Novais, S. Allende, D. Altbir +3
The magnetic vortex structure, that is present in several nanoscopic systems, is stable and can be manipulated through the application of a magnetic field or a spin polarized curre…
Non-topological condensates for the self-dual Chern-Simons-Higgs model
Manuel del Pino, Pierpaolo Esposito, Pablo Figueroa +1
For the abelian self-dual Chern-Simons-Higgs model we address existence issues of periodic vortex configurations -- the so-called condensates-- of non-topological type as …
