Higher harmonics of the magnetoplasmon in strongly coupled Coulomb and Yukawa systems
T. Ott, M. Bonitz, P. Hartmann +1
The generation of higher harmonics of the magnetoplasmon frequency which has recently been reported in strongly coupled two-dimensional Yukawa systems is investigated in detail and…
Effects of disorder on the transmission of nodal fermions through a d-wave superconductor
J. K. Asboth, A. R. Akhmerov, M. V. Medvedyeva +1
The bulk microwave conductivity of a dirty d-wave superconductor is known to depend sensitively on the range of the disorder potential: long-range scattering enhances the conductiv…
Full-revivals in 2-D Quantum Walks
M. Stefanak, B. Kollar, T. Kiss +1
Recurrence of a random walk is described by the Polya number. For quantum walks, recurrence is understood as the return of the walker to the origin, rather than the full-revival of…
A Microscopic View on the Mott transition in Chromium-doped V2O3
S. Lupi, L. Baldassarre, B. Mansart +18
V2O3 is the prototype system for the Mott transition, one of the most fundamental phenomena of electronic correlation. Temperature, doping or pressure induce a metal to insulator t…
Quantum relaxation after a quench in systems with boundaries
Ferenc Iglói, Heiko Rieger
We study the time-dependence of the magnetization profile, m_l(t), of a large finite open quantum Ising chain after a quench. We observe a cyclic variation, in which starting with…
Griffiths phases in the contact process on complex networks
Géza Ódor, Róbert Juhász, Claudio Castellano +1
Dynamical processes occurring on top of complex networks have become an exciting area of research. Quenched disorder plays a relevant role in general dynamical processes and phase…
