Collective modes in a bilayer dipolar fermi gas and the dissipationless drag effect
(Springer, 2013)We consider the collective modes of a bilayer dipolar Fermi system in which the particles interact via long range (∼1/r 3) interaction. Assuming that each layer has a background flow which varies little and that the dynamics ... 
Disorderfree localization around the conduction band edge of crossing and kinked silicon nanowires
(A I P Publishing LLC, 2015)We explore ballistic regime quantum transport characteristics of oxideembedded crossing and kinked silicon nanowires (NWs) within a largescale empirical pseudopotential electronic structure framework, coupled to the ... 
Electroluminescence efficiency enhancement in quantum dot lightemitting diodes by embedding a silver nanoisland layer
(WileyVCH Verlag, 2015)A colloidal quantum dot lightemitting diode (QLED) is reported with substantially enhanced electroluminescence by embedding a thin layer of Ag nanoislands into hole transport layer. The maximum external quantum efficiency ... 
Enhanced nonvolatile memory characteristics with quattrolayer graphene nanoplatelets vs. 2.85nm Si nanoparticles with asymmetric Al2O3/HfO2 tunnel oxide
(Springer New York LLC, 2015)In this work, we demonstrate a nonvolatile metaloxide semiconductor (MOS) memory with Quattrolayer graphene nanoplatelets as charge storage layer with asymmetric Al2O3/HfO2 tunnel oxide and we compare it to the ... 
Exciton induced directed motion of unconstrained atoms in an ultracold gas
(Institute of Physics Publishing, 2017)We demonstrate that through localised Rydberg excitation in a threedimensional cold atom cloud atomic motion can be rendered directed and nearly confined to a plane, without spatial constraints for the motion of individual ... 
Fano effect in a double Tshaped interferometer
(Springer, 2009)We study the coherent transport in a onedimensional lead with two sidecoupled quantum dots using the Keldysh's Green function formalism.The effect of the interdot Coulomb interaction is taken into account by computing ... 
Quantum marginal problem and Nrepresentability
(IOP, 2006)A fermionic version of the quantum marginal problem was known from the early sixties as Nrepresentability problem. In 1995 it was mentioned by the National Research Council of the USA as one of ten most prominent research ... 
Role of the environmental spectrum in the decoherence and dephasing of multilevel quantum systems
(The American Physical Society, 2005)We examine the effect of multilevels on decoherence and dephasing properties of a quantum system consisting of a nonideal two level subspace, identified as the qubit, and a finite set of higher energy levels above this ... 
Rydberg aggregates
(Institute of Physics Publishing, 2018)We review Rydberg aggregates, assemblies of a few Rydberg atoms exhibiting energy transport through collective eigenstates, considering isolated atoms or assemblies embedded within clouds of cold groundstate atoms. We ... 
Spintronic properties of zigzagedged triangular graphene flakes
(AIP Publishing LLC, 2010)We investigate quantum transport properties of triangular graphene flakes with zigzag edges by using first principles calculations. Triangular graphene flakes have large magnetic moments which vary with the number of ... 
Strongly ScaleDependent Charge Transport From Interconnections of Silicon Quantum Dots and Nanowires
(Cambridge University Press, 2017)We present the first characterization of strongly scaledependent charge transport of a unique, hierarchical complex topology: an interconnected random network of silicon quantum dots (QDs) and nanowires. We show that this ... 
Tuning the degree of oxidation and electron delocalization of poly(3,4ethylenedioxythiophene):poly(styrenesulfonate) with solidelectrolyte
(Elsevier, 201710)We report on the effects of ionic interaction on the electronic structure of PEDOT:PSS where the oxidation state of PEDOT is an import aspect for various applications. Additional ionic interactions are introduced and ...
