Today’s information technology relies on electronics that consumes a huge amount of energy, the electrons within electric currents can also transfer a form of angular momentum called spin. Spin-based electronics or spintronics, that exploits spin current, has the potential to …
Peak laser intensity demonstrations have occurred on specific Nd:glass-based lasers: * the Vulcan PW in the UK at 1 × 10^21 W/cm2 (2004); * the Ti:sapphirebased HERCULES laser at the University of Michigan, USA at 1 × 10^22 W/cm2 (2004) …
Canadian researchers at the Advanced Laser Light Source (ALLS) facility at INRS, generated 300 terawatt laser pulses (3 joules for a 10-femtosecond pulse). They plan to repeat the experiment with an energy of 3 petawatts (3000 trillion Watts – 13 …
Dr. Steven Howe identified an antimatter niche for the acceleration of small unmanned interstellar probes. Small amounts of antimatter can be used to initiate fission events whose daughters provided thrust. * use a dedicated customer $670 million accelerator to produce …
Exotic states called Kohn anomalies been found for the first time in an unexpected type of material and this could lead to new quantum devices. The researchers induced a Kohn anomaly, which was previously thought to exist only in metals, …
Honeywell has released access to its trapped ion quantum computer with a quantum volume of 64. The previous best quantum computers were IBM and Google at a quantum volume of 32. Honeywell claims to have the most powerful quantum computer …
A personal, handheld device emitting high-intensity ultraviolet light to disinfect areas by killing the novel coronavirus is now feasible, according to researchers at Penn State, the University of Minnesota and two Japanese universities. Finding a new material with the right …
LPP fusion discovered the FF-2Bs prototype anode was cracked. They have used the shutdown time, necessitated by both the crack and the coronavirus, to complete the design of our new switches, and to redesign the anode. They are aiming to …
New simulations by a research team led by UC San Diegos Alexey Arefiev point the way toward making matter from light. The process starts by aiming a high-power laser at a target to generate a magnetic field as strong as …
Acta Astronautica – Future interstellar rockets may use laser-induced annihilation reactions for relativistic drive Until now, no technology was known that would be able to give rocket exhaust at relativistic speed and a high enough momentum for relativistic travel. Here, …
