Electron Structure Near Abrupt Edges in 2DEG under Strong Magnetic Field
I. Bartos, B. Rosenstein
Energies and wave functions of edge states in twodimensional electron gas are evaluated for a finite step potential barrier model. The spectrum, instead of smooth bending of Landau…
Coarse-grained entropy rates for characterization of complex time series
Milan Palus
A method for classification of complex time series using coarse-grained entropy rates (CER's) is presented. The CER's, which are computed from information-theoretic functionals --…
Weakly coupled states on branching graphs
Pavel Exner
We consider a Schrödinger particle on a graph consisting of links joined at a single point. Each link supports a real locally integrable potential ; the self--adjo…
A Search for Leptoquarks at HERA
H1 Collaboration, S. Aid et al
A search for leptoquarks at HERA was performed in H1 using 1994 data corresponding to an integrated luminosity of about $3 \pb^{-1}$. Single leptoquarks were searched for i…
Jets and Energy Flow in Photon-Proton Collisions at HERA
H1-Collaboration, S. Aid et al
Properties of the hadronic final state in photoproduction events with large transverse energy are studied at the electron-proton collider HERA. Distributions of the transverse ener…
New Incommensurate Elongated-Triangle Phase in Quartz
P. Saint-Gregoire, I. Luk'yanchuk, E. Snoeck +2
We present for the first time the evidence for a thermodynamically stable incommensurate elongated-triangle () phase in quartz observed by transmission electron microscopy at…
