Two-magnon bound state causes ultrafast thermally induced magnetisation switching
(Nature Publishing Group, 2013-11)
There has been much interest recently in the discovery of thermally induced magnetisation switching using femtosecond laser excitation, where a ferrimagnetic system can be switched deterministically without an applied ...
Nonperturbative dynamical decoupling with random control
(Nature Publishing Group, 2014-08-29)
Parametric fluctuations or stochastic signals are introduced into the rectangular pulse sequence to investigate the feasibility of random dynamical decoupling. In a large parameter region, we find that the out-of-order ...
New generation of two-dimensional spintronic systems realized by coupling of Rashba and Dirac fermions
(Nature Publishing Group, 2015-08-04)
Intriguing phenomena and novel physics predicted for two-dimensional (2D) systems formed by electrons in Dirac or Rashba states motivate an active search for new materials or combinations of the already revealed ones. Being ...
Higher order vortex gyrotropic modes in circular ferromagnetic nanodots
(Nature Publishing Group, 2014-04-25)
Magnetic vortex that consists of an in-plane curling magnetization configuration and a needle-like core region with out-of-plane magnetization is known to be the ground state of geometrically confined submicron soft magnetic ...
Efficient Gate-tunable light-emitting device made of defective boron nitride nanotubes: from ultraviolet to the visible
(Nature Publishing Group, 2013-09)
Boron nitride is a promising material for nanotechnology applications due to its two-dimensional graphene-like, insulating, and highly-resistant structure. Recently it has received a lot of attention as a substrate to grow ...
Analysis of SUMOylated proteins using SUMO-traps
(Nature Publishing Group, 2013-04-22)
SUMO-modified proteins are recognized by SUMO interacting motifs (SIMs), thus triggering diverse cellular responses. Here SIMs were used to develop SUMO-traps to capture endogenous SUMOylated proteins. Our results show ...
Fault-tolerant almost exact state transmission
(Nature Publishing Group, 2013-11)
We show that a category of one-dimensional XY-type models may enable high-fidelity quantum state transmissions, regardless of details of coupling configurations. This observation leads to a fault-tolerant design of a state ...
Time-dependent electron phenomena at surfaces
(US National Academy of Sciences, 2011-01)
Femtosecond and subfemtosecond time scales typically rule electron dynamics at metal surfaces. Recent advance in experimental techniques permits now remarkable precision in the description of these processes. In particular, ...
Spin-helical Dirac states in graphene induced by polar-substrate surfaces with giant spin-orbit interaction: a new platform for spintronics
(Nature Publishing Group, 2014-11-04)
Spintronics, or spin electronics, is aimed at efficient control and manipulation of spin degrees of freedom in electron systems. To comply with demands of nowaday spintronics, the studies of electron systems hosting giant ...
Symmetry restoration and quantumness reestablishment
(Nature Publishing Group, 2014-09-18)
A realistic quantum many-body system, characterized by a generic microscopic Hamiltonian, is accessible only through approximation methods. The mean field theories, as the simplest practices of approximation methods, ...
