A Degenerate Singlet-Triplet Qubit with All-Electrical Orthogonal Control
Phuong X. Nguyen, Konstantinos Tsoukalas, Jann H. Ungerer +8
Singlet-triplet qubits offer an attractive encoding for semiconductor quantum computing, combining ancilla-free readout, reduced sensitivity to common-mode noise, and baseband volt…
Trion Hall effect in electron-hole double layers
Raghav Chaturvedi, Phuong X. Nguyen, Patrick Knüppel +4
The realization of Coulomb coupled electron-hole double layers in 2D semiconductor heterostructures has enabled the thermodynamic and transport studies of equilibrium exciton fluid…
Quantum oscillations in a dipolar excitonic insulator
Phuong X. Nguyen, Raghav Chaturvedi, Bo Zou +5
Quantum oscillations in magnetization or resistivity are a defining feature of metals subject to an external magnetic field. The phenomenon is generally not expected in insulators…
Relativistic Mott transition in strongly correlated artificial graphene
Liguo Ma, Raghav Chaturvedi, Phuong X. Nguyen +4
The realization of graphene has provided a bench-top laboratory for quantum electrodynamics. The low-energy excitations of graphene are two-dimensional massless Dirac fermions with…
A degenerate trion liquid in atomic double layers
Phuong X. Nguyen, Raghav Chaturvedi, Liguo Ma +5
Trions are a three-particle bound state of electrons and holes. Experimental realization of a trion liquid in the degenerate quantum limit would open a wide range of phenomena in q…
