Competition of fermion pairing, magnetism, and charge order in the spin-doped attractive Hubbard gas
Thomas Hartke, Botond Oreg, Chunhan Feng +7
The tension between fermion pairing and magnetism affects numerous strongly correlated electron systems, from high-temperature cuprates to twisted bilayer graphene. Exotic forms of…
In search of exotic pairing in the Hubbard model: many-body computation and quantum gas microscopy
Chunhan Feng, Thomas Hartke, Yuan-Yao He +5
Pair density waves and exotic superconductivity have long been of strong interest, and have attracted much recent attention. We present a joint theoretical and experimental explora…
Direct observation of non-local fermion pairing in an attractive Fermi-Hubbard gas
Thomas Hartke, Botond Oreg, Carter Turnbaugh +2
Pairing of fermions lies at the heart of superconductivity, the hierarchy of nuclear binding energies and superfluidity of neutron stars. The Hubbard model of attractively interact…
Quantum Register of Fermion Pairs
Thomas Hartke, Botond Oreg, Ningyuan Jia +1
Fermions are the building blocks of matter, forming atoms and nuclei, complex materials and neutron stars. Our understanding of many-fermion systems is however limited, as classica…
Doublon-hole correlations and fluctuation thermometry in a Fermi-Hubbard gas
Thomas Hartke, Botond Oreg, Ningyuan Jia +1
We report on the single atom and single site-resolved detection of the total density in a cold atom realization of the 2D Fermi-Hubbard model. Fluorescence imaging of doublons is a…
Spin Transport in a Mott Insulator of Ultracold Fermions
Matthew A. Nichols, Lawrence W. Cheuk, Melih Okan +6
Strongly correlated materials are expected to feature unconventional transport properties, such that charge, spin, and heat conduction are potentially independent probes of the dyn…
On-Chip Quantum Dot Light Source for Quantum State Readout
Y. -Y. Liu, J. Stehlik, X. Mi +2
We use microwave radiation generated by a semiconductor double quantum dot (DQD) micromaser for charge state detection. A cavity is populated with n_c ~ 6000 photons by driving a c…
Phase locking of a semiconductor double quantum dot single atom maser
Y. -Y. Liu, T. Hartke, J. Stehlik +1
We experimentally study the phase stabilization of a semiconductor double quantum dot (DQD) single atom maser by injection locking. A voltage-biased DQD serves as an electrically t…
Threshold Dynamics of a Semiconductor Single Atom Maser
Y. -Y. Liu, J. Stehlik, C. Eichler +5
We demonstrate a single-atom maser consisting of a semiconductor double quantum dot (DQD) that is embedded in a high quality factor microwave cavity. A finite bias drives the DQD o…
Fast charge sensing of a cavity-coupled double quantum dot using a Josephson parametric amplifier
J. Stehlik, Y. -Y. Liu, C. M. Quintana +3
We demonstrate fast readout of a double quantum dot (DQD) that is coupled to a superconducting resonator. Utilizing parametric amplification in a nonlinear operational mode, we imp…
