The production of entropy, which means increasing the degree of disorder in a system, is an inexorable tendency in the macroscopic world owing to the second law of thermodynamics. This makes the processes described by classical ...
An undesirable trait found in traditionally processed superalloys does not exist in a 3-D-printed, nickel-based superalloy, according to a team of materials scientists who think this could lead to new manufacturing techniques ...
An international team of scientists developed the world's first anti-laser for a nonlinear Bose-Einstein condensate of ultracold atoms. For the first time, scientists have demonstrated that it is possible to absorb the selected ...
In an inertial frame of reference, a body with zero net force acting on it does not accelerate. When scientists speak of inertial frames of reference, they're invoking a coordinate system with no external influences, and ...
Potentially paving the way toward advanced computers, lasers or optical devices, University of Wisconsin-Madison researchers have revealed new effects in tiny electronic devices called quantum dots.
An international group of physicists managed for the first time to experimentally observe the transition between two states of matter, propagating polariton-solitons and a Bose-Einstein condensate. Furthermore, physicists ...
Heisenberg's uncertainty principle, the fundamental impossibility of simultaneously measuring properties such as position and momentum, is at the heart of quantum theory. Â鶹ÒùÔºicists at ETH Zurich have now demonstrated an ...
The behavior of electrons in a material is typically difficult to predict. Novel insight comes now from experiments and simulations performed by a team led by ETH physicists who have studied electronic transport properties ...
An international research team produced an analog of a solid-body crystal lattice from polaritons, hybrid photon-electron quasiparticles. In the resulting polariton lattice, the energy of certain particles does not depend ...
With the help of electronic microscopy, scientists have tracked defects in the surface of two-dimensional photonic crystals. But there are difficulties with bulk photonic crystals. There is no way for scientists to research ...
