Floquet engineering tunes ultracold molecule interactions and produces two-axis twisting dynamics

Posted by in categories: engineering, quantum physics

The interactions between quantum spins underlie some of the universe’s most interesting phenomena, such as superconductors and magnets. However, physicists have difficulty engineering controllable systems in the lab that replicate these interactions.

Do we live in a shell universe?

Posted by in categories: cosmology, quantum physics

A small black hole must work harder against gravity to keep from collapsing. In rapidly rotating black holes, the Ni shell would collapse to a torus, as possibly reflected in the dramatic photos of .

At a deeper level, the gravity/Λ mechanism might be seen as a kind of quantum overlay of the Ni solutions, a possible step towards reconciliation of the quantum gravity and general relativity perspectives.

Cosmologists will not be quick to endorse a shell universe. There is still much heavy lifting still to do, for instance, in matching the Ni solutions to the observed universe. Dark matter and dark energy will not lightly be cast aside. But if I am right, the universe is not as you may always have thought.

FBI: Reported cryptocurrency losses reached $5.6 billion in 2023

Posted by in categories: cryptocurrencies, government, internet

The FBI says that 2023 was a record year for cryptocurrency fraud, with total losses exceeding $5.6 billion, based on nearly 70,000 reports received through the Internet Crime Complaint Center (IC3).

This marks a 45% increase in losses compared to the previous year, driven primarily by investment fraud, which accounted for 71% of the total cryptocurrency losses. Other types of fraud contributing to the statistics include tech support scams, call center fraud, and government impersonation.

The vast majority of the reported losses ($4.8 billion) were incurred by U.S. citizens, followed by Cayman Islands ($196M), Mexico ($127M), Canada ($72M), the UK ($59M), India ($44M), and Australia ($25M).

New PIXHELL acoustic attack leaks secrets from LCD screen noise

Posted by in categories: cybercrime/malcode, mobile phones

A novel acoustic attack named ‘PIXHELL’ can leak secrets from air-gapped and audio-gapped systems, and without requiring speakers, through the LCD monitors they connect to.

In a PIXHELL attack, malware modulates the pixel patterns on LCD screens to induce noise in the frequency range of 0–22 kHz, carrying encoded signals within those acoustic waves that can be captured by nearby devices such as smartphones.

The researchers’ tests showed that data exfiltration is possible at a maximum distance of 2 meters (6.5 ft), achieving a data rate of 20 bits per second (bps).
