The Quark Side - Quantum Physics Podcast

A theoretical study by Rodrigo Berté proposes a surprising connection between nanophotonics and gravitational waves. Using the concept of bound states in the continuum (BICs), researchers explore whether gravitational energy could become localized within spacetime rather than propagating freely.

If these states can be converted into quasi-BICs, they could open new possibilities for detecting subtle gravitational signals and probing the high-frequency behavior of gravity.

New research in Physical Review Letters challenges assumptions about how dark photons interacted with the early universe.

Computer simulations show that nonlinear effects may have stopped their energy conversion far earlier than expected, meaning the cosmos may not have been heated as previously thought. The result reopens a broad range of dark matter possibilities and could reshape future searches for these elusive particles.

Modern physics may need to move beyond the idea of point-like particles to reconcile quantum mechanics with general relativity.

A new non-local approach replaces isolated points with extended topological structures, potentially avoiding the infinities that arise at extreme scales. By treating spacetime as an emergent phenomenon rooted in quantum entanglement, researchers are exploring a radically different picture of reality.

Scientists at Lawrence Berkeley National Laboratory have created a stable Bose-Einstein condensate in an ultrathin solid-state device. Using excitons, the quantum fluid can exist at much higher temperatures than traditional condensates and can be controlled with electric voltage or magnetic fields.

The breakthrough could make exotic quantum phenomena easier to study while opening new possibilities for optoelectronics, quantum simulation, and future quantum technologies.

The XENONnT experiment has pushed the search for dark matter to unprecedented sensitivity.

Using a massive liquid-xenon detector and machine learning, researchers found no definitive signal but set powerful new limits on axion-like particles and dark photons. Reaching the “neutrino fog” also marks a major milestone, helping guide the next generation of dark matter experiments.

Researchers have uncovered a striking irreversibility gap in quantum entanglement using so-called flower states.

The study shows that creating these states can require vastly more entanglement than can be recovered, while challenging the role of squashed entanglement as a reliable measure under non-entangling operations. The results also reveal exact distillation limits and a surprisingly simple communication protocol that reaches them.

Researchers have uncovered new insights into the irreversibility of quantum entanglement using a special class of quantum states called flower states.

The study reveals a significant gap between the entanglement that can be extracted and the resources needed to create it, establishing new limits on how quantum entanglement can be manipulated. The findings could deepen our understanding of quantum information and resource theory.

Researchers at the Tokyo University of Science have discovered microscopic particles that can behave in ways that appear to violate Newton’s third law.

Under electric fields, unequal particle interactions create a self-sustaining “chasing” motion, preventing static clusters and producing dynamic structures that constantly break apart and reorganize. The discovery could help explain collective behavior in biological systems and enable new generations of microrobots.

MIT physicists have observed, for the first time, how different electron phases emerge and coexist in a quantum material. Laser pulses revealed two distinct transition mechanisms: one phase returns uniformly, while another forms isolated pockets that expand like ice in water.

The discovery could help scientists control complex electronic properties and advance quantum devices and next-generation superconductors.

Scientists have developed a groundbreaking method to visualize molecular orbitals in 3D, revealing the quantum wave functions of molecules with unprecedented detail.

Using photoelectron spectroscopy, advanced algorithms, and a lab-based soft X-ray source, the technique eliminates the need for massive synchrotron facilities. With femtosecond resolution, it could enable scientists to watch chemical reactions unfold in real time, opening a new era of molecular imaging.
