Parametrically amplified Josephson plasma waves in YBa_2Cu_3O_(6+x): evidence for local superconducting fluctuations up to the pseudogap temperature
Marios H. Michael, Eugene Demler, Patrick Lee
Experiments that subject underdoped (YBCO) to intense terahertz pulses at temperatures between the transition temperature and the pseudogap scale $T^*…
The Ultrafast Superconducting Diode Effect
E. Wang, M. Chavez-Cervantes, J. Satapathy +8
Nonreciprocal transport is generally observed in superconductors in which time reversal and inversion symmetries are simultaneously broken. This effect, which may become one of the…
Universal magnetic energy scale in the doped Fermi-Hubbard model
Radu Andrei, Ivan Morera, Jonathan B. Curtis +2
Magnetic correlations of doped Mott insulators hold the key to the unusual characteristics of many quantum materials. Recent experiments with ultracold atoms in optical lattices ha…
Theory of Two-Qubit Spectroscopy of Quantum Many-Body Systems
Hossein Hosseinabadi, Pavel E. Dolgirev, Sarang Gopalakrishnan +3
Multi-qubit quantum sensors are rapidly emerging as platforms that extend the capabilities of conventional single-qubit sensing. In this work we show how suitable pulse sequences a…
Color Centers and Hyperbolic Phonon Polaritons in Hexagonal Boron Nitride: A New Platform for Quantum Optics
Jie-Cheng Feng, Johannes Eberle, Sambuddha Chattopadhyay +3
Hyperbolic phonon polaritons (HPPs) in hexagonal boron nitride (hBN) confine mid-infrared light to deep-subwavelength scales and may offer a powerful route to strong light-matter i…
Enhancing superconductivity using thermal bosons
Ekaterina Vlasiuk, Manfred Salmhofer, Eugene Demler +1
We investigate how the strong coupling of a superconductor to thermal bosons can enhance its superconducting critical temperature. To tackle this problem, we use a renormalization…
