Direct observation of Higgs mode oscillations in the pump-probe photoemission spectra of electron-phonon mediated superconductors
A. F. Kemper, M. A. Sentef, B. Moritz +2
Using the non-equilibrium Keldysh formalism, we solve the equations of motion for electron-phonon superconductivity, including an ultrafast pump field. We present results for time-…
MilkyWay@home: Harnessing volunteer computers to constrain dark matter in the Milky Way
Heidi Jo Newberg, Matthew Newby, Travis Desell +3
MilkyWay@home is a volunteer computing project that allows people from every country in the world to volunteer their otherwise idle processors to Milky Way research. Currently, mor…
More chips off of Asteroid (4) Vesta: characterization of eight Vestoids and their HED meteorite analogs
Paul S. Hardersen, Vishnu Reddy, Rachel Roberts +1
This work reports high quality NIR spectra, and their respective interpretations, for eight Vp type asteroids, as defined by Carvano et al. (2010), that were observed at the NASA I…
Numerical exploration of spontaneous broken symmetries in multi-orbital Hubbard models
Y. F. Kung, C. -C. Chen, B. Moritz +3
We study three proposals for broken symmetry in the cuprate pseudogap - oxygen antiferromagnetism, orbital loop currents, and circulating currents involving apex oxygens -…
Direct spectroscopic evidence for phase competition between the pseudogap and superconductivity in BiSrCaCuO
Makoto Hashimoto, Elizabeth A. Nowadnick, Rui-Hua. He +16
In the high-temperature () cuprate superconductors, increasing evidence suggests that the pseudogap, existing below the pseudogap temperature *, has a distinct broken ele…
Early Observations and Analysis of the Type Ia SN 2014J in M82
G. H. Marion, D. J. Sand, E. Y. Hsiao +23
We present optical and near infrared (NIR) observations of the nearby Type Ia SN 2014J. Seventeen optical and twenty-three NIR spectra were obtained from 10 days before (10d) to…
Stellar rotational periods in the planet hosting open cluster Praesepe
Geza Kovacs, Joel D. Hartman, Gaspar A. Bakos +6
By using the dense coverage of the extrasolar planet survey project HATNet, we Fourier analyze 381 high-probability members of the nearby open cluster Praesepe (Beehive/M44/NGC 263…
The Brightest Cluster Galaxy in Abell 85: The Largest Core Known so far
O. López-Cruz, C. Añorve, M. Birkinshaw +5
We have found that the brightest cluster galaxy (BCG) in Abell~85, Holm 15A, displays the largest core so far known. Its cusp radius, kpc ($4.26^{\prime\prime…
Chelyabinsk meteorite explains unusual spectral properties of Baptistina Asteroid Family
Vishnu Reddy, Juan Sanchez, William Bottke +8
We investigated the spectral and compositional properties of Chelyabinsk meteorite to identify its possible parent body in the main asteroid belt. Our analysis shows that the meteo…
Dynamic competition between spin density wave order and superconductivity in underdoped
M. Yi, Y. Zhang, Z. -K. Liu +13
An intriguing aspect of unconventional superconductivity is that it always appears in the vicinity of other competing phases, whose suppression brings the full emergence of superco…
HAT-P-54b: A hot jupiter transiting a 0.64 Msun star in field 0 of the K2 mission
G. Á. Bakos, J. D. Hartman, W. Bhatti +22
We report the discovery of HAT-P-54b, a planet transiting a late K dwarf star in field 0 of the NASA K2 mission. We combine ground-based photometric light curves with radial veloci…
Effect of dynamical spectral weight redistribution on effective interactions in time-resolved spectroscopy
A. F. Kemper, M. A. Sentef, B. Moritz +2
The redistribution of electrons in an ultrafast pump-probe experiment causes significant changes to the effective interaction between electrons and bosonic modes. We study the infl…
The rich frequency spectrum of the triple-mode variable AC And
G. Kovacs, G. A. Bakos, J. D Hartman
Fourier analysis of the light curve of AC And from the HATNet database reveals the rich frequency structure of this object. Above 30 components are found down to the amplitude of 3…
HAT-P-49b: A 1.7 M_J Planet Transiting a Bright 1.5 M_S F-Star
A. Bieryla, J. D. Hartman, G. A. Bakos +18
We report the discovery of the transiting extrasolar planet HAT-P-49b. The planet transits the bright (V = 10.3) slightly evolved F-star HD 340099 with a mass of 1.54M_S and a radi…
Theory of pump-probe photoemission in graphene: Ultrafast tuning of Floquet bands and local pseudospin textures
M. A. Sentef, M. Claassen, A. F. Kemper +4
The control of physical properties of solids with short laser pulses is an intriguing prospect of ultrafast materials science. Continuous-wave high-frequency laser driving with cir…
