Unlike conventional phases of matter, the so-called non-equilibrium quantum phases are defined by their dynamical and time-evolving properties — a behavior that cannot be captured by traditional equilibrium thermodynamics. One particularly rich class of non-equilibrium states arises in Floquet systems — quantum systems that are periodically driven in time. This rhythmic driving can give rise to entirely new forms of order that cannot exist under any equilibrium conditions, re

Researchers at The City College of New York have shown how a quantum emitter, the nitrogen-vacancy (NV) center in diamond, interacts in unexpected ways with a specially engineered photonic structure when moved around with a scanning tip. The study, led by Carlos A. Meriles, Martin and Michele Cohen Professor of Physics in the Division of Science and entitled “Emission of Nitrogen–Vacancy Centres in Diamond Shaped by Topological Photonic Waveguide Modes,” appears in the journa

Researchers from Delft University of Technology in The Netherlands have been able to see the magnetic nucleus of an atom switch back and forth in real time. They read out the nuclear ‘spin’ via the electrons in the same atom through the needle of a scanning tunneling microscope. To their surprise, the spin remained stable for several seconds, offering prospects for enhanced control of the magnetic nucleus. The research, published in Nature Communications, is a step forward fo

Nearly a decade after they first demonstrated that soft materials could guide the formation of superconductors, Cornell researchers have achieved a one-step, 3D printing method that produces superconductors with record properties. The advance, detailed Aug. 19 in Nature Communications, builds on years of interdisciplinary work led by Ulrich Wiesner, the Spencer T. Olin Professor in the Department of Materials Science and Engineering, and could improve technologies such as

Three nano glass spheres cling to one another. They form a tower-like cluster, similar to when you pile three scoops of ice cream on top of one another – only much smaller. The diameter of the nano cluster is ten times smaller than that of a human hair. With the help of an optical device and laser beams, researchers at ETH Zurich have succeeded in keeping such objects almost completely motionless in levitation. This is significant when it comes to the future development of qu

The research team studied how phonons interfere with each other by looking at the shape of their signal in Raman spectroscopy, a technique that measures the vibrational modes of a material. The spectrum revealed a sharply asymmetric line shape and in some cases showed a complete dip, forming an antiresonance pattern characteristic of intense interference. The effect proved highly sensitive to the specificities of the silicon carbide surface. The comparison between three diffe
