Quantum dynamics show ‘memory’ depends on whether states or observables evolve

by quasarn01 | Mar 2, 2026 | Latest in Physics

An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings show that a quantum process can appear memoryless from one perspective while retaining memory from another. The discovery opens new research...

Research reveals cosmic tug-of-war behind the Crab Pulsar’s zebra stripes

The Western Stone, Jerusalem, Israel. 1.2 million pounds. The Ramesseum statue, Thebes, Egypt. Two million pounds. The Trilithon at the Temple of Jupiter, Baalbek, Lebanon. 4.8 million pounds. So basically spread all over our planet, ancient sites reveal engineering...

How to weigh a killer asteroid at 22 kilometers per second

by quasarn01 | Mar 2, 2026 | Astronomy

Estimating a mass for a potentially hazardous asteroid (PHA) is perhaps the single most important thing to understand about it, after its trajectory. Actually doing so isn’t easy though, as the mass for objects in the tens to hundreds of kilometers in size are...

Mott and Kondo insulators—how external stimuli can modify electronic energy bands

by quasarn01 | Mar 2, 2026 | Latest in Physics

A study from the Research Center for Materials Nanoarchitectonics (MANA) has uncovered a theoretical mechanism showing how the electronic band structures of strongly correlated insulators can be reshaped by spin and charge perturbations, opening up new possibilities...
