Variational order for forced Lagrangian systems
D. Martín de Diego, R. Sato Martín de Almagro
We are able to derive the equations of motion for forced mechanical systems in a purely variational setting, both in the context of Lagrangian or Hamiltonian mechanics, by duplicat…
On the distribution of the eigenvalues of the area operator in loop quantum gravity
J. Fernando Barbero, Juan Margalef-Bentabol, Eduardo J. S. Villaseñor
We study the distribution of the eigenvalues of the area operator in loop quantum gravity concentrating on the part of the spectrum relevant for isolated horizons. We first show th…
The CARMENES search for exoplanets around M dwarfs - HD 147379b: A nearby Neptune in the temperate zone of an early-M dwarf
A. Reiners, I. Ribas, M. Zechmeister +169
We report on the first star discovered to host a planet detected by radial velocity (RV) observations obtained within the CARMENES survey for exoplanets around M dwarfs. HD 147379…
Two dimensional collective electron magnetotransport, oscillations and chaos in a semiconductor superlattice
L. L. Bonilla, M. Carretero, A. Segura
When quantized, traces of classically chaotic single particle systems include eigenvalue statistics and scars in eigenfuntions. Since 2001, many theoretical and experimental works…
Duality and the universality class of the three-state Potts antiferromagnet on plane quadrangulations
Jian-Ping Lv, Youjin Deng, Jesper Lykke Jacobsen +2
We provide a new criterion based on graph duality to predict whether the 3-state Potts antiferromagnet on a plane quadrangulation has a zero- or finite-temperature critical point,…
Asymptotic decay and non-rupture of viscous sheets
Marco A. Fontelos, G. Kitavtsev, R. M. Taranets
For a nonlinear system of coupled PDEs, that describes evolution of a viscous thin liquid sheet and takes account of surface tension at the free surface, we show exponential $(H^1,…
Correlation-induced refrigeration with superconducting single-electron transistors
Rafael Sánchez
A model of a superconducting tunnel junction which refrigerates a nearby metallic island without any particle exchange is presented. Heat extraction is mediated by charge fluctuati…
Geometrical Structures for Classical and Quantum Probability Spaces
Florio M. Ciaglia, Alberto Ibort, Giuseppe Marmo
On the affine space containing the space of quantum states of finite-dimensional systems there are contravariant tensor fields by means of which it is possible to def…
Transient effects in the translation of bubbles insonated with acoustic pulses of finite duration
Elena Igualada-Villodre, Ana Medina-Palomo, Patricia Vega-Martínez +1
The translation of a bubble under the action of an acoustic forcing finds applications in fields ranging from drug delivery to sonoluminesce. This phenomenon has been widely studie…
Differential characters and cohomology of the moduli of flat Connections
Marco Castrillón López, Roberto Ferreiro Pérez
Let be a principal bundle and an invariant polynomial of degree r on the Lie algebra of the structure group. The theory of Chern-Simons differential characters…
Geometric integrators and the Hamiltonian Monte Carlo method
Nawaf Bou-Rabee, Jesús María Sanz-Serna
This paper surveys in detail the relations between numerical integration and the Hamiltonian (or hybrid) Monte Carlo method (HMC). Since the computational cost of HMC mainly lies i…
Operator inequalities implying similarity to a contraction
Glenier Bello-Burguet, Dmitry Yakubovich
Let be a bounded linear operator on a Hilbert space such that \[ α[T^*,T]:=\sum_{n=0}^\infty α_n T^{*n}T^n\ge 0. \] where is a suitable ana…
Assessing Information Transmission in Data Transformations with the Channel Multivariate Entropy Triangle
Francisco J. Valverde-Albacete, Carmen Peláez-Moreno
Data transformation, e.g. feature transformation and selection, is an integral part of any machine learning procedure. In this paper we introduce an information-theoretic model and…
Characteristic distribution: An application to material bodies
V. M. Jiménez, M. de León, M. Epstein
Associated to each material body there exists a groupoid consisting of all the material isomorphisms connecting the points of $\mathcal{…
The CARMENES search for exoplanets around M dwarfs: High-resolution optical and near-infrared spectroscopy of 324 survey stars
A. Reiners, M. Zechmeister, J. A. Caballero +170
The CARMENES radial velocity (RV) survey is observing 324 M dwarfs to search for any orbiting planets. In this paper, we present the survey sample by publishing one CARMENES spectr…
Fundamental groups of formal Legendrian and horizontal embedding spaces
Eduardo Fernández, Javier Martínez-Aguinaga, Francisco Presas
We compute the fundamental group of each connected component of the space of formal Legendrian embeddings in R3. We use it to show that previous examples in the literature of non t…
Entanglement manipulation and distillability beyond LOCC
Eric Chitambar, Julio I. de Vicente, Mark W. Girard +1
When a quantum system is distributed to spatially separated parties, it is natural to consider how the system evolves when the parties perform local quantum operations with classic…
Tunable Resonance Coupling in Single Si Nanoparticle-Monolayer WS2 Structures
Sergey Lepeshov, Mingsong Wang, Alex Krasnok +8
Two-dimensional semiconducting transition metal dichalcogenides (TMDCs) are extremely attractive materials for optoelectronic applications in the visible and near-IR range. Here, w…
Boundedness results for commutators with BMO functions via weighted estimates: a comprehensive approach
Árpád Bényi, José María Martell, Kabe Moen +2
We present a unified method to obtain weighted estimates of linear and multilinear commutators with BMO functions, that is amenable to a plethora of operators and functional settin…
Boundedness of averaging operators on geometrically doubling metric spaces
J. M. Aldaz
We prove that averaging operators are uniformly bounded on for all geometrically doubling metric measure spaces, with bounds independent of the measure. From this result, the…
Analyzing gender inequality through large-scale Facebook advertising data
David Garcia, Yonas Mitike Kassa, Angel Cuevas +4
Online social media are information resources that can have a transformative power in society. While the Web was envisioned as an equalizing force that allows everyone to access in…
On the pointwise domination of a function by its maximal function
J. M. Aldaz
We show that under rather general circumstances, the almost everywhere pointwise inequality is equivalent to a weak form of the Lebesgue density theorem, for to…
The CARMENES search for exoplanets around M dwarfs. First visual-channel radial-velocity measurements and orbital parameter updates of seven M-dwarf planetary systems
T. Trifonov, M. Kürster, M. Zechmeister +166
Context: The main goal of the CARMENES survey is to find Earth-mass planets around nearby M-dwarf stars. Seven M-dwarfs included in the CARMENES sample had been observed before wit…
Spectral gaps and discrete magnetic Laplacians
John Stewart Fabila-Carrasco, Fernando Lledó, Olaf Post
The aim of this article is to give a simple geometric condition that guarantees the existence of spectral gaps of the discrete Laplacian on periodic graphs. For proving this, we an…
