Evidence for Merger-Driven Growth in Luminous, High-z, Obscured AGN in the CANDELS/COSMOS Field
J. L. Donley, J. Kartaltepe, D. Kocevski +27
While major mergers have long been proposed as a driver of both AGN activity and the M-sigma relation, studies of moderate to high redshift Seyfert-luminosity AGN hosts have found…
Anomalous and regular transport in spin 1/2 chains: AC conductivity
Ramsés J. Sánchez, Vipin Kerala Varma, Vadim Oganesyan
We study magnetization transport in anisotropic spin- chains governed by the integrable XXZ model with and without integrability-breaking perturbations at high temperatures ($…
Linear Progress with Exponential Decay in Weakly Hyperbolic Groups
Matt Sunderland
A random walk on a separable, geodesic hyperbolic metric space converges to the boundary with probability one when the step distribution supports two indepen…
Noise-tolerant quantum speedups in quantum annealing without fine tuning
Eliot Kapit, Vadim Oganesyan
Quantum annealing is a powerful alternative model for quantum computing, which can succeed in the presence of environmental noise even without error correction. However, despite gr…
SDSS-IV MaNGA: Evidence of the importance of AGN feedback in low-mass galaxies
Samantha J. Penny, Karen L. Masters, Rebecca Smethurst +15
We present new evidence for AGN feedback in a subset of 69 quenched low-mass galaxies ( M, ) selected from the first t…
Two-dimensional anisotropic random walks: fixed versus random column configurations for transport phenomena
Endre Csáki, Miklós Csörgő, Antónia Földes +1
We consider random walks on the square lattice of the plane along the lines of Heyde (1982, 1993) and den Hollander (1994), whose studies have in part been inspired by the so-calle…
Inner-model reflection principles
Neil Barton, Andrés Eduardo Caicedo, Gunter Fuchs +3
We introduce and consider the inner-model reflection principle, which asserts that whenever a statement in the first-order language of set theory is true in the set-theoreti…
Intertwined and vestigial order with ultracold atoms in multiple cavity modes
Sarang Gopalakrishnan, Yulia E. Shchadilova, Eugene Demler
Atoms in transversely pumped optical cavities "self-organize" by forming a density wave and emitting superradiantly into the cavity mode(s). For a single-mode cavity, the propertie…
Thermalization near integrability in a dipolar quantum Newton's cradle
Yijun Tang, Wil Kao, Kuan-Yu Li +5
Isolated quantum many-body systems with integrable dynamics generically do not thermalize when taken far from equilibrium. As one perturbs such systems away from the integrable poi…
MBL-mobile: Quantum engine based on many-body localization
Nicole Yunger Halpern, Christopher David White, Sarang Gopalakrishnan +1
Many-body-localized (MBL) systems do not thermalize under their intrinsic dynamics. The athermality of MBL, we propose, can be harnessed for thermodynamic tasks. We illustrate this…
Optical fluxes in coupled -symmetric photonic structures
Li Ge, Konstantinos G. Makris, Lingxuan Zhang
In this work we first examine transverse and longitudinal fluxes in a -symmetric photonic dimer using a coupled-mode theory. Several surprising understandings are obtained…
Dynamical Masses of Low Mass Stars in the Taurus and Ophiuchus Star Forming Regions
M. Simon, S. Guilloteau, E. di Folco +8
We report new dynamical masses for 5 pre-main sequence (PMS) stars in the L1495 region of the Taurus star-forming region (SFR) and 6 in the L1688 region of the Ophiuchus SFR. Since…
Recurrence of quadratic differentials for harmonic measure
Vaibhav Gadre, Joseph Maher
We consider random walks on the mapping class group that have finite first moment with respect to the word metric, whose support generates a non-elementary subgroup and contains a…
State observation and sensor selection for nonlinear networks
Aleksandar Haber, Ferenc Molnar, Adilson E. Motter
A large variety of dynamical systems, such as chemical and biomolecular systems, can be seen as networks of nonlinear entities. Prediction, control, and identification of such nonl…
Self-dual quasiperiodic systems with power-law hopping
Sarang Gopalakrishnan
We introduce and explore a family of self-dual models of single-particle motion in quasiperiodic potentials, with hopping amplitudes that fall off as a power law with exponent .…
A model of the generic Vopěnka principle in which the ordinals are not Mahlo
Victoria Gitman, Joel David Hamkins
The generic Vopěnka principle, we prove, is relatively consistent with the ordinals being non-Mahlo. Similarly, the generic Vopěnka scheme is relatively consistent with the ordinal…
Anomalous Transport Properties of Dense QCD in a Magnetic Field
Vivian de la Incera
Despite recent advancements in the study and understanding of the phase diagram of strongly interacting matter, the region of high baryonic densities and low temperatures has remai…
Probing Slow Relaxation and Many-Body Localization in Two-Dimensional Quasi-Periodic Systems
Pranjal Bordia, Henrik Lüschen, Sebastian Scherg +4
In a many-body localized (MBL) quantum system, the ergodic hypothesis breaks down completely, giving rise to a fundamentally new many-body phase. Whether and under which conditions…
Massively parallel implementation and approaches to simulate quantum dynamics using Krylov subspace techniques
Marlon Brenes, Vipin Kerala Varma, Antonello Scardicchio +1
We have developed an application and implemented parallel algorithms in order to provide a computational framework suitable for massively parallel supercomputers to study the unita…
Defect states emerging from a non-Hermitian flat band of photonic zero modes
Bingkun Qi, Lingxuan Zhang, Li Ge
We show the existence of a flat band consisting of photonic zero modes in a gain and loss modulated lattice system, as a result of the underlying non-Hermitian particle-hole symmet…
Finite-size anomalies of the Drude weight: role of symmetries and ensembles
Ramsés J. Sánchez, Vipin Kerala Varma
We revisit the subtelties of computing the high temperature spin stiffness of the spin- XXZ chain using exact diagonalization to analyze its dependence on system symmetrie…

R. Nilsson, A. Veicht, P. A. Giorla Godfrey +23
The nearby Sun-like star GJ 758 hosts a cold substellar companion, GJ 758 B, at a projected separation of 30 AU, previously detected in high-contrast multi-band photometr…
Surface Gravities for 228 M, L, and T Dwarfs in the NIRSPEC Brown Dwarf Spectroscopic Survey
Emily C. Martin, Gregory N. Mace, Ian S. McLean +6
We combine 131 new medium-resolution (R~2000) J-band spectra of M, L, and T dwarfs from the Keck NIRSPEC Brown Dwarf Spectroscopic Survey (BDSS) with 97 previously published BDSS s…
Fractality in nonequilibrium steady states of quasiperiodic systems
Vipin Kerala Varma, Clélia de Mulatier, Marko Znidaric
We investigate the nonequilibrium response of quasiperiodic systems to boundary driving. In particular we focus on the Aubry-André-Harper model at its metal-insulator transition an…
