Mixed-order phase transition of the contact process near multiple junctions
R. Juhász, F. Iglói
We have studied the phase transition of the contact process near a multiple junction of semi-infinite chains by Monte Carlo simulations. As opposed to the continuous transition…
Domain wall profiles in Co/Ir/Pt(111) ultrathin films: influence of the Dzyaloshinskii-Moriya interaction
Gy. J. Vida, E. Simon, L. Rózsa +2
We perform a study of domain walls in Co/Ir/Pt(111) (n = 0,1,...,6) films by a combined approach of first-principles calculations and spin dynamics simulations. We determine th…
Ultrasensitive 1D field-effect phototransistor: CHNHPbI nanowire sensitized individual carbon nanotube
M. Spina, B. Náfrádi, H. M. Tóháti +4
Field-effect phototransistors were fabricated based on individual carbon nanotubes (CNTs) sensitized by CHNHPbI nanowires (MAPbINW). These devices represent light r…
Optical phonons for Peierls chains with long-range Coulomb interactions
Máté Timár, Gergely Barcza, Florian Gebhard +1
We consider a chain of atoms that are bound together by a harmonic force. Spin-1/2 electrons that move between neighboring chain sites (Hückel model) induce a lattice dimerization…
Giant magnetoresistance in electrodeposited Co-Cu/Cu multilayers: origin of absence of oscillatory behaviour
I. Bakonyi, E. Simon, B. G. Tóth +2
A detailed study of the evolution of the magnetoresistance was performed on electrodeposited Co/Cu multilayers with Cu layer thicknesses ranging from 0.5 nm to 4.5 nm. For thin Cu…
Spontaneous generation of a temperature anisotropy in a strongly coupled magnetized plasma
T. Ott, M. Bonitz, P. Hartmann +1
A magnetic field was recently shown to enhance field-parallel heat conduction in a strongly correlated plasma whereas cross-field conduction is reduced. Here we show that in such p…
