The Mass of the Black Hole in the X-ray Binary Nova Muscae 1991
Jianfeng Wu, Jerome A. Orosz, Jeffrey E. McClintock +4
The optical counterpart of the black-hole soft X-ray transient Nova Muscae 1991 has brightened by mag since its return to quiescence 23 years ago. We present the f…
Charge Puddles in Graphene Near the Dirac Point
S. Samaddar, I. Yudhistira, S. Adam +2
The charge carrier density in graphene on a dielectric substrate such as SiO displays inhomogeneities, the so-called charge puddles. Because of the linear dispersion relation i…
Leading gradient correction to the kinetic energy for two-dimensional fermion gases
Martin-Isbjörn Trappe, Yink Loong Len, Hui Khoon Ng +2
Density functional theory (DFT) is notorious for the absence of gradient corrections to the two-dimensional (2D) Thomas-Fermi kinetic-energy functional; it is widely accepted that…
The topology of large Open Connectome networks for the human brain
Michael T. Gastner, Géza Ódor
The structural human connectome (i.e.\ the network of fiber connections in the brain) can be analyzed at ever finer spatial resolution thanks to advances in neuroimaging. Here we a…
String Solving with Word Equations and Transducers: Towards a Logic for Analysing Mutation XSS (Full Version)
Anthony W. Lin, Pablo Barcelo
We study the fundamental issue of decidability of satisfiability over string logics with concatenations and finite-state transducers as atomic operations. Although restricting to o…
Regular Symmetry Patterns (Technical Report)
Anthony W. Lin, Truong Khanh Nguyen, Philipp Rümmer +1
Symmetry reduction is a well-known approach for alleviating the state explosion problem in model checking. Automatically identifying symmetries in concurrent systems, however, is c…
Local spectroscopy of moiré-induced electronic structure in gate-tunable twisted bilayer graphene
Dillon Wong, Yang Wang, Jeil Jung +16
Twisted bilayer graphene (tBLG) forms a quasicrystal whose structural and electronic properties depend on the angle of rotation between its layers. Here we present a scanning tunne…
Least-bias state estimation with incomplete unbiased measurements
J. Rehacek, Z. Hradil, Y. S. Teo +4
Measuring incomplete sets of mutually unbiased bases constitutes a sensible approach to the tomography of high-dimensional quantum systems. The unbiased nature of these bases optim…
The initial system-bath state via the maximum-entropy principle
Jibo Dai, Yink Loong Len, Hui Khoon Ng
The initial state of a system-bath composite is needed as the input for prediction from any quantum evolution equation to describe subsequent system-only reduced dynamics or the no…
The Linear KdV Equation with an Interface
Bernard Deconinck, Natalie E. Sheils, David A. Smith
The interface problem for the linear Korteweg-de Vries (KdV) equation in one-dimensional piecewise homogeneous domains is examined by constructing an explicit solution in each doma…
THz conductivity of graphene on boron nitride
Ashley M. DaSilva, Jeil Jung, Shaffique Adam +1
The conductivity of graphene on a boron nitride substrate exhibits features in the terahertz (THz) and infrared (IR) frequency regimes that are associated with the periodic moiré p…
Expressive Path Queries on Graph with Data
Pablo Barcelo, Gaelle Fontaine, Anthony Widjaja Lin
Graph data models have recently become popular owing to their applications, e.g., in social networks and the semantic web. Typical navigational query languages over graph databases…
L-groups and parameters for covering groups
Martin H. Weissman
We incorporate covers of quasisplit reductive groups into the Langlands program, defining an L-group associated to such a cover. We work with all covers that arise from extensions…
Interaction driven metal-insulator transition in strained graphene
Ho-Kin Tang, E. Laksono, J. N. B. Rodrigues +3
The question of whether electron-electron interactions can drive a metal to insulator transition in graphene under realistic experimental conditions is addressed. Using three repre…
Graded Betti numbers of cycle graphs and standard Young tableaux
Steven Klee, Matthew T. Stamps
We give a bijective proof that the Betti numbers of a minimal free resolution of the Stanley-Reisner ring of a cycle graph (viewed as a one-dimensional simplicial complex) are give…
Tunable room-temperature ferromagnet using an iron-oxide and graphene oxide nanocomposite
Aigu L. Lin, J. N. B. Rodrigues, Chenliang Su +7
Magnetic materials have found wide application ranging from electronics and memories to medicine. Essential to these advances is the control of the magnetic order. To date, most ro…
Transport and particle-hole asymmetry in graphene on boron nitride
Ashley M. DaSilva, Jeil Jung, Shaffique Adam +1
All local electronic properties of graphene on a hexagonal boron nitride (hBN) substrate exhibit spatial moiré patterns related to lattice constant and orientation differences betw…
Quantum transport and observation of Dyakonov-Perel spin-orbit scattering in monolayer MoS
H. Schmidt, I. Yudhistira, L. Chu +4
Monolayers of group 6 transition metal dichalcogenides are promising candidates for future spin-, valley-, and charge-based applications. Quantum transport in these materials refle…
The SMARTS Multi-epoch Optical Spectroscopy Atlas (SAMOSA): Using Emission Line Variability to Probe the Location of the Blazar Gamma-emitting Region
Jedidah C. Isler, C. M. Urry, C. Bailyn +6
We present multi-epoch optical spectroscopy of seven southern Fermi-monitored blazars from 2008 - 2013 using the Small and Medium Aperture Research Telescope System (SMARTS), with…
Transport and magnetotransport in 3D Weyl Semimetals
Navneeth Ramakrishnan, Mirco Milletari, Shaffique Adam
We theoretically investigate the transport and magnetotransport properties of three-dimensional Weyl semimetals. Using the RPA-Boltzmann transport scattering theory for electrons s…
