Attosecond time-scale multi-electron collisions in the Coulomb four-body problem: traces in classical probability densities
Agapi Emmanouilidou, Jan Michael Rost
In the triple ionization of the Li ground state by single photon absorption the three electrons escape to the continuum mainly through two collision sequences with individual colli…
Theory of tunneling spectroscopy in UPd2Al3
David Parker, Peter Thalmeier
There is still significant debate about the symmetry of the order parameter in the heavy-fermion superconductor UPdAl, with proposals for cos(k3), cos(2k3), sin(k3),and…
Comparison of Ising magnet on directed versus undirected Erdos-Renyi and scale-free network
M. A. Sumour, A. H. El-Astal, F. W. S. Lima +2
Scale-free networks are a recently developed approach to model the interactions found in complex natural and man-made systems. Such networks exhibit a power-law distribution of nod…
The concept of correlated density and its application
Klaus Morawetz, Pavel Lipavský, Jan Koláček +2
The correlated density appears in many physical systems ranging from dense interacting gases up to Fermi liquids which develop a coherent state at low temperatures, the superconduc…
Intra-cellular transport by single-headed kinesin KIF1A: effects of single-motor mechano-chemistry and steric interactions
Philip Greulich, Ashok Garai, Katsuhiro Nishinari +2
In eukaryotic cells, many motor proteins can move simultaneously on a single microtubule track. This leads to interesting collective phenomena like jamming. Recently we reported ({…
Optimal Stochastic Enhancement of Photoionization
Kamal P. Singh, Jan M. Rost
The effect of noise on the nonlinear photoionization of an atom due to a femtosecond pulse is investigated in the framework of the stochastic Schrödinger equation. A modest amount…
Universal properties of highly frustrated quantum magnets in strong magnetic fields
Oleg Derzhko, Johannes Richter, Andreas Honecker +1
The purpose of the present paper is two-fold. On the one hand, we review some recent studies on the low-temperature strong-field thermodynamic properties of frustrated quantum spin…
Relation between the one-particle spectral function and dynamic spin susceptibility in superconducting BiSrCaCuO
D. Inosov, S. Borisenko, I. Eremin +9
Angle resolved photoemission spectroscopy (ARPES) provides a detailed view of the renormalized band structure and, consequently, is a key to the self-energy and the single-particle…
Break-down of the density-of-states description of scanning tunneling spectroscopy in supported metal clusters
Mario De Menech, Ulf Saalmann, Martin E. Garcia
Low-temperature scanning tunneling spectroscopy allows to probe the electronic properties of clusters at surfaces with unprecedented accuracy. By means of quantum transport theory,…
Renormalization of the quasiparticle hopping integrals by spin interactions in layered copper oxides
L. Hozoi, S. Nishimoto, C. de Graaf
Holes doped within the square CuO2 network specific to the cuprate superconducting materials have oxygen 2p character. We investigate the basic properties of such oxygen holes by w…
New critical behavior in unconventional ferromagnetic superconductors
Dimo I. Uzunov
New critical behavior in unconventional superconductors and superfluids is established and described by the Wilson-Fisher renormalization-group method. For certain ordering symmetr…
Ratcheting up energy by means of measurement
L. S. Schulman, B. Gaveau
The destruction of quantum coherence can pump energy into a system. For our examples this is paradoxical since the destroyed correlations are ordinarily considered negligible. Math…
DNA: From rigid base-pairs to semiflexible polymers
Nils B. Becker, Ralf Everaers
The sequence-dependent elasticity of double-helical DNA on a nm length scale can be captured by the rigid base-pair model, whose strains are the relative position and orientation o…
Liquid transport generated by a flashing field-induced wettability ratchet
Karin John, Uwe Thiele
We develop and analyze a model for ratchet-driven macroscopic transport of a continuous phase. The transport relies on a field-induced dewetting-spreading cycle of a liquid film wi…
Spin susceptibility in bilayered cuprates: resonant magnetic excitations
Ilya Eremin, Dirk K. Morr, Andrey V. Chubukov +1
We study the momentum and frequency dependence of the dynamical spin susceptibility in the superconducting state of bilayer cuprate superconductors. We show that there exists a res…
Ferromagnetism in the t-t' Hubbard model: interplay of lattice, band dispersion, and interaction effects studied within a Goldstone-mode preserving scheme
Sudhakar Pandey, Avinash Singh
Ferromagnetism in the Hubbard model is investigated on sc, bcc, and fcc lattices using a systematic inverse-degeneracy () expansion which incorporates self-energy and v…
Fano resonance in discrete lattice models: controlling lineshapes with impurities
Arunava Chakrabarti
The possibility of controlling Fano lineshapes in the electronic transmission is addressed in terms of a simple discrete model within a tight binding framework, in which a finite s…
An {\it ab initio} relativistic coupled-cluster theory of dipole and quadrupole polarizabilities: Applications to a few alkali atoms and alkaline earth ions
B. K. Sahoo
We present a general approach within the relativistic coupled-cluster theory framework to calculate exactly the first order wave functions due to any rank perturbation operators. U…
Nematic order in the multiple-spin exchange model on the triangular lattice
Tsutomu Momoi, Nic Shannon
We discuss the possibility of finding n-type nematic order in the vicinity of a FM phase in the multiple--spin exchange model on the triangular lattice. We study this problem both…
How random is your heart beat?
K. Urbanowicz, J. J. Zebrowski, R. Baranowski +1
We measure the content of random uncorrelated noise in heart rate variability using a general method of noise level estimation using a coarse grained entropy. We show that usually…
Random matrix analysis of network Laplacians
Sarika Jalan, Jayendra N. Bandyopadhyay
We analyze eigenvalues fluctuations of the Laplacian of various networks under the random matrix theory framework. Analyses of random networks, scale-free networks and small-world…
Heat conduction through a trapped solid: effect of structural changes on thermal conductance
Debasish Chaudhuri, Abhishek Chaudhuri, Surajit Sengupta
We study the conduction of heat across a narrow solid strip trapped by an external potential and in contact with its own liquid. Structural changes, consisting of addition and dele…
