Elastic Coupling between Nonferroelastic Domain Walls

Nava Setter, Alexander Tagantsev, Petr Yudin, Konstantin Shapovalov

We reveal a strong elastic interaction between nonferroelastic domain walls in ferroelectric thin films. This interaction, having no analogue in bulk materials, is governed by elastic fields that are associated with the domain walls and extends to distance ...

HFI energetic particle effects: characterization, removal, and simulation

Julien Lesgourgues, Fabio Finelli

We describe the detection, interpretation, and removal of the signal resulting from interactions of high energy particles with the Planck High Frequency Instrument (HFI). There are two types of interactions: heating of the 0.1 K bolometer plate; and glitch ...

Glassy low-energy spin fluctuations and anisotropy gap in La1.88Sr0.12CuO4

Henrik Moodysson Rønnow, Joël Mesot, Johan Juul Chang

We present high-resolution triple-axis neutron scattering studies of the high-temperature superconductor La1.88Sr0.12CuO4 (Tc=27 K). The temperature dependence of the low-energy incommensurate magnetic fluctuations reveals distinctly glassy features. The g ...

Plasmon evolution and charge-density wave suppression in potassium intercalated 2H-TaSe2

Helmuth Berger

We have investigated the influence of potassium intercalation on the formation of the charge-density wave (CDW) instability in 2H-TaSe2 by means of electron energy-loss spectroscopy and density functional theory. Our observations are consistent with a fill ...

Interface-confined mixing and buried partial dislocations for Ag bilayer on Pt(111)

Harald Brune, Daniele Passerone

The trigonal strain-relief pattern formed by an Ag bilayer on Pt(111) is a prominent example for dislocation networks and their use as nanotemplates. However, its atomic structure has not been solved. Combining scanning tunneling microscopy, low-energy ion ...

Can a Metal Surface Repel Electric Charges?

Primoz Rebernik Ribic

We show that the interaction between a surface and a charge packet moving parallel to it can become repulsive above a critical relativistic energy. We find that this is true for a lossless dielectric surface and also for a Drude metallic surface-in apparen ...

Classical and Quantum Critical Phenomena in the Dipolar Antiferromagnet LiErF4

Neda Nikseresht Ghanepour

The collective behavior of systems consisting of interacting dipoles is a subject of considerable studies. The anisotropic nature of such interactions opens an arena to explore fundamental questions in correlated electron physics, ranging from quantum enta ...

Theory of inelastic light scattering in spin-1 systems: Resonant regimes and detection of quadrupolar order

Frédéric Mila, Frédéric Alexis Michaud, François Vernay

Motivated by the lack of an obvious spectroscopic probe to investigate nonconventional order such as quadrupolar orders in spin S > 1/2 systems, we present a theoretical approach to inelastic light scattering for spin-1 quantum magnets in the context of a ...

Influence of the elastic properties of the phases on the coefficient of thermal expansion of a metal matrix composite

Martin Vetterli, Ludger Weber, Reza Tavangar Hamzehkolaei

Copper matrix composites reinforced with low thermal expansion ceramic particles, i.e. SiO2, AIN and diamond, in the range of ceramic volume fractions between 0.55 and 0.85 have been prepared by gas pressure infiltration and are characterized by their coef ...
