Vortices in the Ocean of Vacuum: How Spin Dictates the Birth of Matter ⚡ экспресс
Original: "Vortex structures in electron-positron pair production by two-colored fields"
Collisions of laser flashes give birth to vortices in the vacuum, whose shape is determined by spin — the intrinsic rotation of particles.

In empty vacuum, strong electromagnetic fields can birth electron-positron pairs. New research shows: the delay between laser pulses turns these particles sometimes into chaos, sometimes into ordered vortices. The pattern is dictated by spin — like a dance with strict rules. This effect provides an ultra-precise tool for studying the quantum world.
🎯 The most powerful lasers still can't reach the Schwinger limit — the field capable of birthing pairs from absolute emptiness. However, the trick of colliding pulses lets us see this effect without waiting for record-breaking powers.
