13.12.2016 by Kaido Reivelt

Author(s): Cunfeng Cheng, Aernout P. P. van der Poel, Paul Jansen, Marina Quintero-Pérez, Thomas E. Wall, Wim Ubachs, and Hendrick L. Bethlem

Gas molecules can be slowed down, cooled, and made to erupt like a fountain using electric fields, enabling their study over unprecedentedly long time scales.

Experimental Demonstration of a Resonator-Induced Phase Gate in a Multiqubit Circuit-QED System

13.12.2016 by Kaido Reivelt

Author(s): Hanhee Paik, A. Mezzacapo, Martin Sandberg, D. T. McClure, B. Abdo, A. D. Córcoles, O. Dial, D. F. Bogorin, B. L. T. Plourde, M. Steffen, A. W. Cross, J. M. Gambetta, and Jerry M. Chow

A quantum phase gate that reduces the need for frequency matching is implemented using four superconducting qubits in a three-dimensional architecture, overcoming a scaling hurdle for these devices.

Comment on ‘Lorentz covariance ‘almost’ implies electromagnetism and more’

13.12.2016 by Kaido Reivelt

It is shown that the theory presented in a recently published paper by Sobouti (2015 Eur. J. Phys.
36 [http://dx.doi.org/10.1088/0143-0807/36/6/065036] 065036 ) allows for a straightforward
development of Maxwell’s equations from Coulomb’s law. T…

Spatial variation of the magnetic field inside laminar flows of a perfect conductive fluid

13.12.2016 by Kaido Reivelt

The steady state of a perfect conductive fluid in laminar flow resulting from the ‘Hall effect’ is
studied. Using the Maxwell equations, the spatial variation of the magnetic field in the steady
state is calculated for three cases of different fl…

The macroscopic pancake bounce

13.12.2016 by Kaido Reivelt

We demonstrate that the so-called pancake bounce of millimetric water droplets on surfaces patterned
with hydrophobic posts (Liu et al 2014 Nat. Phys. 10 [http://https://doi.org/10.1038/nphys2980] 515
) can be reproduced on larger scales. In our expe…

Combinatorial approach to exactly solve the 1D Ising model

13.12.2016 by Kaido Reivelt

The Ising model is a well known statistical model which can be solved exactly by various methods.
The most familiar one is the transfer matrix method. Sometimes it can be difficult to approach the
open boundary case rather than periodic boundary ones…

Earth’s Magnetic Fields Could Track Ocean Heat: NASA

12.12.2016 by Kaido Reivelt

As Earth warms, much of the extra heat is stored in the planet’s ocean — but monitoring the magnitude of that heat content is a difficult task.
