### Best of Last Week – Detecting dark matter with GPS, a gel that stops bleeding and the benefits of fasting

### Physicists study magnetism with the roles of position and momentum reversed

(Phys.org) —Normally, the strength of a magnetic field increases as you get closer to a magnet and decreases as you move further away—a concept easily understood when placing magnets near a refrigerator, for instance. ...

### Majorana fermion: Physicists observe elusive particle that is its own antiparticle

Princeton University scientists have observed an exotic particle that behaves simultaneously like matter and antimatter, a feat of math and engineering that could yield powerful computers based on quantum mechanics.

### Most experiments that claim to show the quantum Zeno paradox fall short, study says

(Phys.org) —By their very nature, unstable particles will eventually decay, some faster than others. But according to the quantum Zeno paradox (QZP), an unstable particle that is observed continuously has been said to never ...

### Uncertainty revisited: Novel tradeoffs in quantum measurement

(Phys.org) —There is, so to speak, uncertainty about uncertainty – that is, over the interpretation of how Heisenberg's uncertainty principle describes the extent of disturbance to one observable when measuring another. ...

### Physicists propose measure of macroscopicity; Schrodinger's cat scores a 57

(Phys.org) —The size of an object can be measured in many ways, such as by its mass, volume, or even the number of atoms it contains. And when it comes to quantum physics, "macroscopic" objects are considered to be larger ...

### On the origins of the Schrodinger equation

(Phys.org) —One of the cornerstones of quantum physics is the Schrödinger equation, which describes what a system of quantum objects such as atoms and subatomic particles will do in the future based on its current state. ...

### Ex nihilo: Dynamical Casimir effect in metamaterial converts vacuum fluctuations into real photons

(Phys.org) —In the strange world of quantum mechanics, the vacuum state (sometimes referred to as the quantum vacuum, simply as the vacuum) is a quantum system's lowest possible energy state. While not containing physical ...
