We show that the discrete set of pair amplitudes $A_m$ introduced by Haldane are an angular-momentum resolved generalization Tan two-body contact, which parametrizes universal short-range correlations in atomic quantum gases. The provide a complete description translation-invariant and rotation-invariant states lowest Landau level (LLL), both compressible incompressible. To leading nontrivial o...

The equivalence between neutral particles under rotation and charged in a magnetic field relates phenomena as diverse spinning atomic nuclei, weather patterns, the quantum Hall effect. In their descriptions, translations along different directions do not commute, implying Heisenberg uncertainty relation spatial coordinates. Here, we exploit ability to squeeze non-commuting variables dynamically...

We demonstrate that, contrary to standard wisdom, the lowest-order Josephson coupling is possible between odd- and even-frequency superconductors. The origin of this effect is the induced odd- (even-)frequency pairing component at the interface of bulk even- (odd-)frequency superconductors. The resulting current-phase relation is found to be proportional to cosphi, where phi is the macroscopic ...

A prototype for a dual-band metamaterial-inspired antenna is presented. The antenna consists of a dual-band dipole placed between two meta-surfaces, which are tuned to operate at both dipole bands. In this way, the dipole radiates at a different half-space at each frequency band. Antenna gains as high as 6.1dB and 7.6dB have been measured at the lowand high-frequency bands, respectively, while ...

We use ultrafast X-ray pulses to characterize the lattice response of SrTiO3 when driven by strong terahertz fields. We observe transient changes in the diffraction intensity with a delayed onset with respect to the driving field. Fourier analysis reveals two frequency components corresponding to the two lowest energy zone-center optical modes in SrTiO3. The lower frequency mode exhibits clear ...
