Orthogonality catastrophe and Kondo effect in graphene [PDF]

, 2007
Anderson's orthogonality catastrophe in graphene, at energies close to the Dirac point, is analyzed. It is shown that, in clean systems, the orthogonality catastrophe is suppressed, due to the vanishing density of states at the Dirac point.

Black Holes at the LHC [PDF]

, 2001
If the scale of quantum gravity is near a TeV, the LHC will be producing one black hole (BH) about every second. The BH decays into prompt, hard photons and charged leptons is a clean signature with low background.

Scanning Tunneling Microscopy/Spectroscopy of Vortices in LiFeAs

, 2012
We investigate vortices in LiFeAs using scanning tunneling microscopy/spectroscopy. Zero-field tunneling spectra show two superconducting gaps without detectable spectral weight near the Fermi energy, evidencing fully-gapped multi-band superconductivity.

Double diffractive cross-section measurement in the forward region at LHC

, 2013
The first double diffractive cross-section measurement in the very forward region has been carried out by the TOTEM experiment at the LHC with center-of-mass energy of sqrt(s)=7 TeV. By utilizing the very forward TOTEM tracking detectors T1 and T2, which

Excitonic condensation in a double-layer graphene system

, 2009
The possibility of excitonic condensation in a recently proposed electrically biased double-layer graphene system is studied theoretically. The main emphasis is put on obtaining a reliable analytical estimate for the transition temperature into the ...

Thermal diffractive corrections to Casimir energies

, 2011
We study the interplay of thermal and diffractive effects in Casimir energies. We consider plates with edges, oriented either parallel or perpendicular to each other, as well as a single plate with a slit.

The sub-arcsecond hard X-ray structure of loop footpoints in a solar flare

, 2010
The newly developed X-ray visibility forward fitting technique is applied to Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) data of a limb flare to investigate the energy and height dependence on sizes, shapes, and position of hard X-ray ...

Adlayer core-level shifts of admetal monolayers on transition metal substrates and their relation to the surface chemical reactivity

, 1995
Using density-functional-theory we study the electronic and structural properties of a monolayer of Cu on the fcc (100) and (111) surfaces of the late 4d transition metals, as well as a monolayer of Pd on Mo bcc(110).

Dirac Nodes and Quantized Thermal Hall Effect in the Mixed State of d-wave Superconductors

, 2001
We consider the vortex state of d-wave superconductors in the clean limit. Within the linearized approximation the quasiparticle bands obtained are found to posess Dirac cone dispersion (band touchings) at special points in the Brillouin zone.
