Tunable Quantum Phase Transitions in a Resonant Level Coupled to Two Dissipative Baths
Dong E. Liu, Huaixiu Zheng, Gleb Finkelstein +1
We study tunneling through a resonant level connected to two dissipative bosonic baths: one is the resistive environment of the source and drain leads, while the second comes from…
One-Dimensional Waveguide Coupled to Multiple Qubits: Photon-Photon Correlations
Yao-Lung L. Fang, Huaixiu Zheng, Harold U. Baranger
For a one-dimensional (1D) waveguide coupled to two or three qubits, we show that the photon-photon correlations have a wide variety of behavior, with structure that depends sensit…
Stabilizing Spin Coherence Through Environmental Entanglement in Strongly Dissipative Quantum Systems
Soumya Bera, Serge Florens, Harold U. Baranger +3
The key feature of a quantum spin coupled to a harmonic bath---a model dissipative quantum system---is competition between oscillator potential energy and spin tunneling rate. We s…
Zigzag Phase Transition in Quantum Wires
Abhijit C. Mehta, C. J. Umrigar, Julia S. Meyer +1
We study the quantum phase transition of interacting electrons in quantum wires from a one-dimensional (1D) linear configuration to a quasi-1D zigzag arrangement using quantum Mont…
Unveiling environmental entanglement in strongly dissipative qubits
Soumya Bera, Serge Florens, Harold Baranger +3
The coupling of a qubit to a macroscopic reservoir plays a fundamental role in understanding the complex transition from the quantum to the classical world. Considering a harmonic…
