Down the rabbit hole: how electrons travel through exotic new material
Down the rabbit hole electrons travel exotic new material
2016/3/21
Researchers at Princeton University have observed a bizarre behavior in a strange new crystal that could hold the key for future electronic technologies. Unlike most materials in which elec...
Cosmological multi-black-hole solutions
Einstein Maxwell equation the charged black holes time and space actively the cosmological constant a black hole
2014/12/23
We present simple, analytic solutions to the Einstein-Maxwell equation, which describe an arbitrary number of charged black holes in a spacetime with a positive cosmological constant Λ. In the limit Λ...
Testing cosmic censorship with black hole collisions
Quality of the hole the cosmological constant total quality extreme limit
2014/12/23
There exists an upper limit on the mass of black holes when the cosmological constant Λ is positive. We study the collision of two black holes whose total mass exceeds this limit. Our investigation is...
U duality, D-branes, and black hole emission rates: Agreements and disagreements
Absorption coefficient five dimensions scalar field a black hole the parameter space
2014/12/22
An expression for the spacetime absorption coefficient of a scalar field in a five-dimensional, near-extremal black hole background is derived, which has the same form as that presented by Maldacena a...
Single-hole spectral function and spin-charge separation in the t-J model
Worm hole green's function monte carlo simulation spectral analysis spectral function thermodynamics
2014/12/22
Worm algorithm Monte Carlo simulations of the hole Green function with subsequent spectral analysis were performed for 0.1<~J/t<~0.4 on lattices with up to L×L=32×32 sites at a temperature as low as T...
Hole digging in ensembles of tunneling molecular magnets
Quantum tunneling magnetic molecules monte carlo simulation tunnel lorentz line shape crystal
2014/12/20
The nuclear spin-mediated quantum relaxation of ensembles of tunneling magnetic molecules causes a “hole” to appear in the distribution of internal fields in the system. The form of this hole and its ...

Bias magnetization the molecular rotation the monte carlo simulation magnetization relaxation lattice
2014/12/20
Our work has argued for a particular scaling form governing the distribution M(ξ,t) of magnetization over bias ξ, for a system of dipolar-interacting molecular spins. This form, which was found in Mon...
The thermodynamics of Kaluza–Klein black hole/bubble chains
Bubble surface black holes time and space exchange said sex black hole static
2014/12/19
A Killing bubble is a minimal surface that arises as the fixed surface of a spacelike Killing field. We compute the bubble contributions to the Smarr relations and the mass and tension first laws for ...
Searches For Gravitational Waves From Binary Black Hole Coalescences With Ground-based Laser Interferometers Across a Wide Parameter Space
Binary Black Hole Data Analysis Gravitational-Waves LIGO NINJA Signal Processing
2014/11/20
This is an exciting time for Gravitational Wave (GW) theory and observations. From a theoretical standpoint, the grand-challenge problem of the full evolution of a Binary Black Hole (BBH) system has b...
A new study shows what happens during the destruction of a star as it falls into a black hole, contradicting a 2012 report of the disruption of an exotic helium star.
Is it possible to create a quantum electromagnetic "black hole" at the Large Hadron Collider?

Modeling core-hole screening jellium clusters density functional theory
2012/2/28
The screening of a 2p core-hole in Na clusters is investigated using density functional theory applied to an extended jellium model with an all-electron atom in the center. The study is related to rec...
