Quantum Chemistry in the Age of Quantum Computing
Yudong Cao, Jonathan Romero, Jonathan P. Olson +10
Practical challenges in simulating quantum systems on classical computers have been widely recognized in the quantum physics and quantum chemistry communities over the past century…
Simultaneous X-ray and Infrared Observations of Sagittarius A*'s Variability
H. Boyce, D. Haggard, G. Witzel +11
Emission from Sgr A* is highly variable at both X-ray and infrared (IR) wavelengths. Observations over the last ~20 years have revealed X-ray flares that rise above a quiescent the…
Non-local String Order Parameter in the Kitaev-Heisenberg Ladder
Andrei Catuneanu, Erik S. Sørensen, Hae-Young Kee
We study the spin- Kitaev-Heisenberg (KJ) model in a two-leg ladder. Without a Heisenberg interaction, the Kitaev phase in the ladder model has Majorana fermions with…
Self-correction in Wegner's 3D Ising lattice gauge theory
David Poulin, Roger G. Melko, Matthew B. Hastings
Motivated by the growing interest in self-correcting quantum memories, we study the feasibility of self-correction in classical lattice systems composed of bounded degrees of freed…
Multiple Parameter Dynamic Photoresponse Microscopy for data-intensive optoelectronic measurements of van der Waals heterostructures
Trevor B. Arp, Nathaniel M. Gabor
Quantum devices made from van der Waals (vdW) heterostructures of two dimensional (2D) materials may herald a new frontier in designer materials that exhibit novel electronic prope…
Dipole Distortions in the Intergalactic Medium
Derek Inman, Ue-Li Pen, Francisco Villaescusa-Navarro
Baryonic feedback can significantly modify the spatial distribution of matter on small scales and create a bulk relative velocity between the dominant cold dark matter and the hot…
Local magnetism, magnetic order and spin freezing in the 'nonmetallic metal' FeCrAs
B. M. Huddart, M. T. Birch, F. L. Pratt +7
We present the results of x-ray scattering and muon-spin relaxation (SR) measurements on the iron-pnictide compound FeCrAs. Polarized non-resonant magnetic x-ray scattering…
-epistemic interpretations of quantum theory have a measurement problem
Joshua B. Ruebeck, Piers Lillystone, Joseph Emerson
-epistemic interpretations of quantum theory maintain that quantum states only represent incomplete information about the physical states of the world. A major motivation for th…
Deconfined criticality in the QED Gross-Neveu-Yukawa model: The expansion revisited
Rufus Boyack, Ahmed Rayyan, Joseph Maciejko
The critical properties of the QED Gross-Neveu-Yukawa (GNY) model in 2+1 dimensions with flavors of two-component Dirac fermions are computed to first order in the …
Cluster Cosmology Constraints from the 2500 deg SPT-SZ Survey: Inclusion of Weak Gravitational Lensing Data from Magellan and the Hubble Space Telescope
S. Bocquet, J. P. Dietrich, T. Schrabback +77
We derive cosmological constraints using a galaxy cluster sample selected from the 2500~deg SPT-SZ survey. The sample spans the redshift range and contains 343 c…
Logarithmic Upturn in Low-Temperature Electronic Transport as a Signature of d-Wave Order in Cuprate Superconductors
Xiaoqing Zhou, D. C. Peets, Benjamin Morgan +12
In cuprate superconductors, high magnetic fields have been used extensively to suppress superconductivity and expose the underlying normal state. Early measurements revealed insula…
Planning in Dynamic Environments with Conditional Autoregressive Models
Johanna Hansen, Kyle Kastner, Aaron Courville +1
We demonstrate the use of conditional autoregressive generative models (van den Oord et al., 2016a) over a discrete latent space (van den Oord et al., 2017b) for forward planning w…
Control and Coherence Time Enhancement of the 0- Qubit
Agustin Di Paolo, Arne L. Grimsmo, Peter Groszkowski +2
Kitaev's 0- qubit encodes quantum information in two protected, near-degenerate states of a superconducting quantum circuit. In a recent work, we have shown that the coherence t…
Quantum communication with time-bin encoded microwave photons
Philipp Kurpiers, Marek Pechal, Baptiste Royer +10
Heralding techniques are useful in quantum communication to circumvent losses without resorting to error correction schemes or quantum repeaters. Such techniques are realized, for…
Unusual rotating magnetocaloric effect in the hexagonal ErMnO3 single crystal
M. Balli, S. Jandl, P. Fournier +2
It is known that orthorhombic RMnO3 multiferroics (R = magnetic rare earth) with low symmetry exhibit a large rotating magnetocaloric effect because of their strong magnetocrystall…
Optimization of neutron diffraction from phase-gratings
B. Heacock, D. Sarenac, D. G. Cory +6
The recent development of phase-grating moiré neutron interferometry promises a wide range of impactful experiments from dark-field imaging of material microstructure to precise me…
Blindfold Baselines for Embodied QA
Ankesh Anand, Eugene Belilovsky, Kyle Kastner +2
We explore blindfold (question-only) baselines for Embodied Question Answering. The EmbodiedQA task requires an agent to answer a question by intelligently navigating in a simulate…
The Cross-correlation of KSZ Effect and 21 cm Intensity Mapping with Tidal Reconstruction
Dongzi Li, Hong-Ming Zhu, Ue-Li Pen
We discuss the possibility of studying diffuse baryon distributions with kinematic Sunyaev-Zel'dovich (kSZ) effect by correlating cosmic microwave background (CMB) temperature fluc…
