Quantum quench in two dimensions using the variational Baeriswyl wave function
(American Physical Society, 2016)By combining the Baeriswyl wave function with equilibrium and timedependent variational principles, we develop a nonequilibrium formalism to study quantum quenches for twodimensional spinless fermions with nearestneighbor ... 
Quantum size effect on the phononinduced Zeeman splitting in a GaAs quantum dot with Gaussian and parabolic confining potentials
(Elsevier B.V., 2008)The Zeeman splitting of the ground and the first excited level of a Gaussian GaAs quantum dot is studied in the presence of electronlongitudinaloptical (LO)phonon interaction incorporating the spin of the electron and ... 
Quantum stereographic projection and the homographic oscillator
(American Physical Society, 1996)The quantum deformation created by the stenographic mapping from S2 to C is studied. It is shown that the resulting algebra is locally isomorphic to su(2) and is an unconventional deformation of which the undeformed limit ... 
Quantum transport through onedimensional aluminum wires
(American Vacuum Society, 2002)Quantum conductance in narrow channels has been well understood by using the twodimensional electron gas, a model system which has been realized in semiconductor heterojunctions. An essential property of this electron ... 
Quantum turnstile operation of singlemolecule magnets
(Institute of Physics Publishing, 2015)The timedependent transport through singlemolecule magnets coupled to magnetic or nonmagnetic electrodes is studied in the framework of the generalized master equation method. We investigate the transient regime induced ... 
Quantum turnstile regime of nanoelectromechanical systems
(American Physical Society, 2020)The effects of a turnstile operation on the currentinduced vibron dynamics in nanoelectromechanical systems (NEMS) are analyzed in the framework of the generalized master equation. In our simulations each turnstile cycle ... 
Quantum Zeno Suppression of Intramolecular Forces
(American Physical Society, 2017)We show that BornOppenheimer surfaces can intrinsically decohere, implying loss of coherence among constituent electronic basis states. We consider the example of interatomic forces due to resonant dipoledipole interactions ... 
Quantumstatistical properties of a Ramantype model
(American Physical Society, 1993)A model describing three boson fields with the decay of Rayleigh mode into the Stokes and vibration (phonon) modes is examined. The problem of exact eigenvalues and eigenstates is reduced to the calculation of zeros of new ... 
Quarter wave Fresnel rhomb with colinear output beam
(Optical Society of America Inc., Washington, DC, United States, 1999)A standard quarter wave (λ/4) Fresnel rhomb laterally displaces the output beam with respect to the input beam. This lateral displacement can cause problems when inserting the rhomb in an already aligned optical setup. ... 
Quasi lumpability, lowerbounding coupling matrices, and nearly completely decomposable Markov chains
(SIAM, 1997)In this paper, it is shown that nearly completely decomposable (NCD) Markov chains are quasilumpable. The state space partition is the natural one, and the technique may be used to compute lower and upper bounds on the ... 
Quasibirthanddeath processes with levelgeometric distribution
(SIAM, 2003)A special class of homogeneous continuoustime quasibirthanddeath (QBD) Markov chains (MCS) which possess levelgeometric (LG) stationary distribution is considered. Assuming that the stationary vector is partitioned ... 
The quasiequivalence problem for a class of köthe spaces
(1997)We consider a subclass of the class of stable nuclear FréchetKöthe spaces, and show that quasiequivalence property holds in this subclass. 
Quasiparticle properties in a quasitwodimensional electron liquid
(Indian Academy of Sciences, 2008)We consider the quasiparticle properties such as the effective mass and spin susceptibility of quasitwodimensional electron systems. The finite quantum well width effects are incorporated into the localfield factors ... 
Quasiparticle properties of a onedimensional electron system interacting with a shortrange potential
(Wiley, 2000)We study the quasiparticle properties of a onedimensional electron gas interacting via a shortrange electronelectron interaction. The electron selfenergy is calculated using the leadingorder dynamicalscreening ... 
Quasitwodimensional Feynman bipolarons
(American Physical Society, 1999)We study the stability criterion for the formation of twodimensionally confined large bipolarons. The electrons are treated as bounded within a parabolic potential well while being coupled to one another via the Fröhlich ... 
Quasilinear actions on products of spheres
(WileyBlackwell Publishing Ltd., 2010)For some small values of f, we prove that if G is a group having a complex (real) representation with fixity f, then it acts freely and smoothly on a product of f+1 spheres with trivial action on homology. © 2010 London ... 
Quasimetallic silicon micromachined photonic crystals
(American Institute of Physics, 2001)We report on fabrication of a layerbylayer photonic crystal using highly doped silicon wafers processed by semiconductor micromachining techniques. The crystals, built using (100) silicon wafers, resulted in an upper ... 
Quaternionic Hilbert spaces and a von Neumann inequality
(Taylor & Francis, 2012)We show that Drury's proof of the generalisation of the von Neumann inequality to the case of contractive rows of Ntuples of commuting operators still holds in the quaternionic case. The arguments require a seemingly new ... 
Queerly Turkish: queer masculinity and national belonging in the image of Zeki Müren
(Routledge, 2018)This article offers an explanation for the lasting appeal of Turkish crossdressing singer Zeki Müren (1931–96). His performances on stage, film, and television interweave avantgarde, modern, and oldfashioned elements. ...
