Triatomic Molecules

In the simplest molecues, diatomic molecules made form two atoms, the vibration and rotation degrees of freedom gives rise to new features such as strong long-range dipolar interactions between molecules, a key ingredient in many quantum simulation and quantum computing proposals. Polyatomic molecules are an exciting new research frontier, as these molecules offer an even...

Atomically Thin Mirrors Made from a Monolayer Semiconductor

Conventional mirrors have fundamental thickness limitations: the skin depth for metallic mirrors, and the wavelength of light for dielectric mirrors. Recently, the Park Group has demonstrated that these limitations can be overcome with the atomically thin semiconductor molybdenum diselenide [1]. To understand how this can be achieved, one has to consider how light is reflected...

Ultracold molecules hold promise for quantum computing

Researchers have taken an important step toward the long-sought goal of a quantum computer, which in theory should be capable of vastly faster computations than conventional computers, for certain kinds of problems. The new work shows that collections of ultracold molecules can retain the information stored in them, for hundreds of times longer than researchers have previously achieved in these materials.

Quantum Nanophotonic Phase Switch with a Single Atom

In analogy to transistors in classical electronic circuits, a quantum optical switch is an important element of quantum circuits and quantum networks. Operated at the fundamental limit where a single quantum of light or matter controls another field or material system, it may enable fascinating applications such as long-distance quantum communication, distributed quantum information processing and...

Scattering Resonances and Bound States for Strongly Interacting Rydberg Polaritons

We provided a theoretical framework, which described slow-light polaritons interacting via atomic Rydberg states. We used a diagrammatic method to analytically derive the scattering properties of two polaritons. We identified new parameter regimes where polariton-polariton interactions were repulsive. Furthermore, in the regime of attractive interactions, we identified multiple two-polariton bound states, calculated their dispersion, and...

Interferometric Probes of Many-body Localization

We proposed a method for detecting many-body localization (MBL) in disordered spin systems. The method involved pulsed, coherent spin manipulations that probed the dephasing of a given spin due to its entanglement with a set of distant spins. It allowed one to distinguish the MBL phase from a non-interacting localized phase and a delocalized phase....
