Quantum Physics Breakthrough: Filipino Physicist Captures ‘Birth of a Torus’ in Quantum System for the First Time

Wazzup Pilipinas!?

In a groundbreaking moment that rewrites the boundaries of quantum science, a team of physicists led by Dr. Jayson Cosme of the University of the Philippines has achieved what was once only a tantalizing theory — the first experimental observation of the "birth of a torus" in a quantum system. This historic scientific milestone, published in the prestigious journal Physical Review Letters, marks a pivotal leap forward in our understanding of how complex quantum behaviors emerge — with implications that stretch from theoretical physics to next-generation technology.

From Heartbeats to Donuts: Understanding the Torus Transition

Imagine a heartbeat rhythm — the steady lub-dub — drawn as a simple loop in a mathematical model called phase space. But when that rhythm becomes erratic or more complex, the simple loop fails. That’s when nature upgrades its metaphor: from a rubber band to a donut — or in scientific terms, a torus. This geometric transformation isn't just a visual curiosity; it's how physicists model systems as they undergo transitions into more intricate, dynamic states.

In classical systems — from the flow of air in a jet engine to the orbits of planets — this “birth of a torus” has been observed and mapped. But in the chaotic, jittery domain of quantum physics, it remained a phantom—predicted, but never seen. Until now.

Time Crystals: Beating Hearts of Quantum Systems

Central to the experiment is a strange but real phenomenon known as the time crystal. Unlike ordinary crystals like diamonds or snowflakes, which are repetitive in space, time crystals exhibit repetition in time. They “tick” back and forth between quantum states, acting like quantum pendulums — beating not because of an internal clock, but because of precise external stimulation, like lasers.

In 2016, time crystals were created by firing rhythmic laser pulses at ultra-cold atoms. But in 2022, Dr. Cosme and his collaborators pushed the envelope further — discovering that even without pulsed lasers, time crystals could emerge. By trapping rubidium atoms between mirrors and bathing them in a continuous laser beam, they saw spontaneous oscillations emerge — giving birth to what they called a continuous time crystal.

Cranking Up the Quantum Heat: From Loop to Torus

Now, in their latest and most daring experiment yet, the team turned the dial even further.

“We showed that cranking up the intensity of light to even brighter or stronger levels will lead to another critical transition,” said Dr. Cosme. And what a transition it was.

As the laser intensity increased, the atoms began behaving erratically — oscillating in a complex, less predictable way. Their movement in phase space shifted from a simple loop to something far more intricate — a torus. The “birth of a torus” was no longer theoretical; it had been captured in real-time.

This wasn’t just a mathematical flourish. It was a revelation. What once existed only in equations and simulations had now been seen in the lab — a cosmic choreography of light and matter at the smallest scales.

The Quantum Future: Detectors, Predictions, and New Frontiers

Why does this matter beyond pure scientific curiosity?

Because systems like these — hovering delicately at the edge of transition — are incredibly sensitive. According to Dr. Cosme, “A system operating close to this transition point can be used as a sensitive detector for light or electromagnetic fields.” In essence, future technology could harness this torus transition to create detectors that are exponentially more responsive to environmental changes.

The team is already preparing their next quantum expedition: exploring whether such dramatic bifurcations in quantum systems can be predicted before they happen — a pursuit that could lead to quantum forecasting tools. They also have their sights on another exotic quantum phenomenon known as the Kibble-Zurek mechanism, which they examined in an earlier publication and now hope to probe more deeply.

A Filipino First, A Global Impact

Dr. Cosme, based at the National Institute of Physics at UP Diliman, has not only brought international acclaim to Filipino science but also placed the Philippines on the quantum map with this unprecedented experiment.

“This is a significant contribution to the global quantum research community,” said peers in the field. Indeed, the breakthrough is a testament to Filipino ingenuity and perseverance in pushing the limits of what is measurable, knowable, and ultimately, possible.

As the quantum world slowly reveals its secrets, the birth of a torus stands as a symbol of how far we’ve come — and a doorway into how much more lies ahead. The rubber band has snapped. The donut has formed. And the universe, in its quantum whisper, has just told us a new story — one that began in the lab of a Filipino physicist, with lasers, mirrors, time crystals, and the courage to imagine the impossible.
