Quantum Resistance Paradox of Low-Dimensional Superfluids
Simon Wili, Meng-Zi Huang, Tommaso Bonaccorsi +7
Resistance in standard conductors decreases with increasing cross-section. Yet, in low-dimensional superconductors and superfluids residual resistance arises from topological fluct…
Variational approach to the dynamics of dissipative quantum impurity models
Yi-Fan Qu, Martino Stefanini, Tao Shi +4
Recent experiments with quantum simulators using ultracold atoms and superconducting qubits have demonstrated the potential of controlled dissipation as a versatile tool for realiz…
Dissipative realization of Kondo models
Martino Stefanini, Yi-Fan Qu, Tilman Esslinger +3
We demonstrate that the Kondo effect can be induced through non-linear dissipative channels, without requiring any coherent interaction on the impurity site. Specifically, we consi…
Galilei covariance of the theory of Thouless pumps
Tilman Esslinger, Gian Michele Graf, Filippo Santi
The Thouless theory of quantum pumps establishes the conditions for quantized particle transport per cycle, and determines its value. When describing the pump from a moving referen…
