Coherent edge mixing and interferometry in quantum Hall bilayers
Stefano Roddaro, Luca Chirolli, Fabio Taddei +2
We discuss the implementation of a beam splitter for electron waves in a quantum Hall bilayer. Our architecture exploits inter-layer tunneling to mix edge states belonging to diffe…
Higher-derivative massive actions from dimensional reduction
Euihun Joung, Karapet Mkrtchyan
A procedure to obtain higher-derivative free massive actions is proposed. It consists in dimensional reduction of conventional two-derivative massless actions, where solutions to c…
A vanishing result for strictly p-convex domains
Daniele Angella, Simone Calamai
In view of A. Andreotti and H. Grauert's vanishing theorem for q-complete domains in C^n, (Théorème de finitude pour la cohomologie des espaces complexes, Bull. Soc. Math. France 9…
Evidence of inter-layer interaction in magneto-luminescence spectra of electron bilayers
Ilirjan Aliaj, Vittorio Pellegrini, Andrea Gamucci +4
Magneto-luminescence studies in electron bilayers reveal the hallmarks of the even-denominator and other quantum Hall states in the intensities and energies of the inter-band optic…
A 125 GeV composite Higgs boson versus flavour and electroweak precision tests
Riccardo Barbieri, Dario Buttazzo, Filippo Sala +2
A composite Higgs boson of 125 GeV mass, only mildly fine-tuned, requires top partners with a semi-perturbative coupling and a mass not greater than about a TeV. We analyze the str…
Measurement of the t t-bar production cross section in pp collisions at sqrt(s) = 7 TeV with lepton + jets final states
CMS Collaboration
A measurement of the t t-bar production cross section in pp collisions at sqrt(s) = 7 TeV is presented. The results are based on data corresponding to an integrated luminosity of 2…
