Regularity properties of Schrödinger integral operators and general oscillatory integrals
Alejandro J. Castro, Anders Israelsson, Wolfgang Staubach +1
We introduce the notion of Schrödinger integral operators and prove sharp local and global regularity results for these (including propagators for the quantum mechanical harmonic o…
Isomorphism types of Rogers semilattices in the analytical hierarchy
Nikolay Bazhenov, Sergey Ospichev, Mars Yamaleev
A numbering of a countable family is a surjective map from the set of natural numbers onto . A numbering is reducible to a numbering if there is an effective pro…
Spinning test particles in the spacetime
Bobir Toshmatov, Daniele Malafarina
We consider the motion of spinning particles in the field of a well known vacuum static axially-symmetric spacetime, known as metric, that can be interpreted as a generalizatio…
Complementarity of Peculiar Velocity Surveys and Redshift Space Distortions for Testing Gravity
Alex G. Kim, Eric V. Linder
Peculiar-velocity surveys of the low-redshift universe have significant leverage to constrain the growth rate of cosmic structure and test gravity. Wide-field imaging surveys combi…
Radically Tunable Ultrafast Photonic Oscillators via Differential Pumping
Yannis Kominis, Anastassios Bountis, Vassilios Kovanis
We present the controllability capabilities for the limit cycles of an extremely tunable photonic oscillator, consisting of two coupled semiconductor lasers. We show that this syst…
Pole Dark Energy
Eric V. Linder
Theories with a pole in the kinetic term have been used to great effect in studying inflation, owing to their quantum stability and attractor properties. We explore the use of such…
The impact of progenitor asymmetries on the neutrino-driven convection in core-collapse supernovae
Rémi Kazeroni, Ernazar Abdikamalov
The explosion of massive stars in core-collapse supernovae may be aided by the convective instabilities that develop in their innermost nuclear burning shells. The resulting fluctu…
Strong resonances at high excitation energy in 17O+alpha resonance scattering
D. K. Nauruzbayev, A. K. Nurmukhanbetova, V. Z. Goldberg +11
The Thick Target Inverse Kinematic (TTIK) approach was used to measure excitation functions for the elastic 17O (α, α) scattering at the initial 17O beam energy of 54.4 MeV. We obs…
Variation-aware Binarized Memristive Networks
Corey Lammie, Olga Krestinskaya, Alex James +1
The quantization of weights to binary states in Deep Neural Networks (DNNs) can replace resource-hungry multiply accumulate operations with simple accumulations. Such Binarized Neu…
Quasinormal modes of magnetized black hole
Bobur Turimov, Bobir Toshmatov, Bobomurat Ahmedov +1
We investigate charged, massive scalar field around static, spherically symmetric black hole immersed into an external asymptotically uniform magnetic field . It is shown that f…
Wigner instability analysis of the damped Hirota equation
Al-Tarazi Assaubay, Alejandro J. Castro, Antonio A. Valido
We address the modulation instability of the Hirota equation in the presence of stochastic spatial incoherence and linear time-dependent amplification/attenuation processes via the…
A Critique of the Smooth Inverse Frequency Sentence Embeddings
Aidana Karipbayeva, Alena Sorokina, Zhenisbek Assylbekov
We critically review the smooth inverse frequency sentence embedding method of Arora, Liang, and Ma (2017), and show inconsistencies in its setup, derivation, and evaluation.
Robust Utility Maximization with Drift and Volatility Uncertainty
Kerem Ugurlu
We give explicit solutions for utility maximization of terminal wealth problem in the presence of Knightian uncertainty in continuous time in a complete market. We…
Global well-posedness for the nonlinear wave equation in analytic Gevrey spaces
Daniel Oliveira da Silva, Alejandro J. Castro
We obtain an asymptotic rate of decay for the radius of spatial analyticity of solutions to the nonlinear wave equation with initial data in the analytic Gevrey spaces.
Static and rotating white dwarfs at finite temperatures
Kuantay Boshkayev
Static and uniformly rotating, cold and hot white dwarfs are investigated both in Newtonian gravity and general theory of relativity, employing the well-known Chandrasekhar equatio…
A toy model for a baby universe inside a black hole
Hrishikesh Chakrabarty, Ahmadjon Abdujabbarov, Daniele Malafarina +1
We present a dynamical toy model for an expanding universe inside a black hole. The model is built by matching a spherically symmetric collapsing matter cloud to an expanding Fried…
Remnant-free Moving Mirror Model for Black Hole Radiation Field
Michael R. R. Good, Eric V. Linder, Frank Wilczek
We analyze the flow of energy and entropy emitted by a class of moving mirror trajectories which provide models for the radiation fields produced by black hole evaporation. The mir…
Characterization of a silicon photomultiplier for the Ultra-Fast Astronomy telescope
Siyang Li, George F. Smoot
We characterized the S13360-3050CS Multi-Pixel Photon Counter (MPPC), a silicon photomultiplier (SiPM) manufactured by Hamamatsu Photonics K.K.. Measurements were obtained inside a…
Enhanced stability, bistability, and exceptional points in saturable active photonic couplers
Yertay Zhiyenbayev, Yannis Kominis, Constantinos Valagiannopoulos +2
A generic photonic coupler with active and lossy parts, gain saturation and asymmetric characteristics is examined. Saturable activity is shown to be able to enhance the overall st…
Color-Coded Fiber-Optic Tactile Sensor for an Elastomeric Robot Skin
Zhanat Kappassov, Daulet Baimukashev, Zharaskhan Kuanyshuly +3
The sense of touch is essential for reliable mapping between the environment and a robot which interacts physically with objects. Presumably, an artificial tactile skin would facil…
