Three robust temperature-drift compensation strategies for a MEMS gravimeter
Victor M. Valenzuela, Daniel Teran, Alejandro Sandoval +4
Gravimeters fabricated with MEMS suffer from temperature-dependent drifts in their long-term stability. We analyze the thermal contributions to the signal, and we propose three mec…
Deviations from Poisson statistics in the spectra of free rectangular thin plates
J. L. López-González, J. A. Franco-Villafañe, R. A. Méndez-Sánchez +4
The counterintuitive fact that wave chaos appears in the bending spectrum of free rectangular thin plates is presented. After extensive numerical simulations, varying the ratio bet…
Quantum gravimetry in the same internal state using composite light Raman pulses
G. A. Olivares-Rentería, D. A. Lancheros-Naranjo, E. Gomez +1
We introduce an atomic gravimetric sequence using Raman-type composite light pulses that excites a superposition of two momentum states with the same internal level. The scheme all…
Photonic realization of the kappa-deformed Dirac equation
Parisa Majari, Emerson Sadurni, Mohammad Reza Setare +2
We show an implementation of a kappa-deformed Dirac equation in tight-binding arrays of photonic waveguides. This is done with a special configuration of couplings extending to sec…
Sound field radiated by a rod
L. A. Razo-López, V. Domínguez-Rocha, John A. Franco-Villafañe +2
We study the acoustical intensity field radiated by a thin cylindrical rod vibrating in its lowest compressional mode. Due to the cylindrical symmetry, the emitted field is measure…
Current vortices in aromatic carbon molecules
Thomas Stegmann, John A. Franco-Villafañe, Yenni P. Ortiz +6
The local current flow through three small aromatic carbon molecules, namely benzene, naphthalene and anthracene, is studied. Applying density functional theory and the non-equilib…
Experimental generation of a flat-top beam profile in a stable ring cavity
A. López-Vázquez, Y. M. Torres, M. S. Billión +3
We create a spatially homogeneous field inside of a ring cavity by combining two transverse modes generated by a single laser through modulation. The interference term between the…
Stern-Gerlach splitters for lattice quasispin
A. S. Rosado, J. A. Franco-Villafañe, C. Pineda +1
We design a Stern-Gerlach apparatus that separates quasispin components on the lattice, without the use of external fields. The effect is engineered using intrinsic parameters, suc…
In-plane vibrations of a rectangular plate: plane wave expansion modelling and experiment
A. Arreola-Lucas, J. A. Franco-Villafañe, G. Báez +1
Theoretical and experimental results for in-plane vibrations of a uniform rectangular plate with free boundary conditions are obtained. The experimental setup uses electromagnetic-…
Microwave emulations and tight-binding calculations of transport in polyacetylene
Thomas Stegmann, John A. Franco-Villafañe, Yenni P. Ortiz +3
A novel approach to investigate the electron transport of cis- and trans-polyacetylene chains in the single-electron approximation is presented by using microwave emulation measure…
Testing quantum transport without decoherence
E. Flores-Olmedo, A. M. Martínez-Argüello, M. Martínez-Mares +3
The coherent electronic transport phenomena through quantum devices is difficult to observe due to thermal smearing and dephasing, the latter induced by inelastic scattering by pho…
On the accuracy of the Timoshenko beam theory above the critical frequency: best shear coefficient
J. A. Franco-Villafañe, R. A. Méndez-Sánchez
We obtain values for the shear coefficient both below and above the critical frequency by comparing the results of the Timoshenko beam theory with experimental data published recen…
Acoustic resonance spectroscopy for the advanced undergraduate laboratory
J. A. Franco-Villafañe, E. Flores-Olmedo, G. Báez +2
We present a simple experiment that allows advanced undergraduates to learn the principles and applications of spectroscopy. The technique, known as acoustic resonance spectroscopy…
Schematic baryon models, their tight binding description and their microwave realization
E. Sadurní, J. A. Franco-Villafañe, U. Kuhl +2
A schematic model for baryon excitations is presented in terms of a symmetric Dirac gyroscope, a relativistic model solvable in closed form, that reduces to a rotor in the non-rela…
First experimental realization of the Dirac oscillator
J. A. Franco-Villafañe, E. Sadurní, S. Barkhofen +3
We present the first experimental microwave realization of the one-dimensional Dirac oscillator, a paradigm in exactly solvable relativistic systems. The experiment relies on a rel…
Doorway States and Billiards
J. A. Franco-Villafañe, J. Flores, J. L. Mateos +3
Whenever a distinct state is immersed in a sea of complicated and dense states, the strength of the distinct state, which we refer to as a doorway, is distributed in their neighbor…
