Experimental studies of topological phenomena for interacting quantum systems are challenging. Here, the authors exploit the analogy between a quantum two-body problem in one dimension and a classical two-dimensional problem, emulating two-photon top

Currently, human magnetic resonance (MR) examinations are becoming highly specialized with a pre-defined and often relatively small target in the body. Conventionally, clinical MR equipment is designed to be universal that compromises its efficiency

In the present work, we study the formation of topological edge states of bound photon pairs, doublons. We consider a one-dimensional array of optical microresonators with tunneling nearest-neighbor couplings, with two photons traveling along the arr

In the present paper, we experimentally study the diffusive dynamics in ensembles of self-propelled and self-rotating bristle-bots. Considering the dependence of the system dynamics on the packing density of robots as well as on the friction between

Magnetic resonance image quality directly depends on the signal-to-noise ratio provided by the receive coil. It was recently shown that wire metasurface can enhance the signal-to-noise ratio of the commercial scanner due to the spatial redistribution

The metasurfaces concept allows developing and advancing the methods to control the near electromagnetic field pattern in almost arbitrary ways. This property, among other things, is making them an essential platform for useful applications, for exam

The sensitivity of magnetic resonance imaging (MRI) is dictated by the signal-to-noise ratio. It was recently noted that the signal-to-noise ratio could be substantially increased via excitation of certain metasurface eigenmodes. Here, we provide a d
