Quantum circuit refrigerator based on quantum dots coupled to normal-metal and superconducting electrodes
S. Mojtaba Tabatabaei, Neda Jahangiri
In quantum dot junctions capacitively coupled to a resonator, electron tunneling through the quantum dot can be used to transfer heat between different parts of the system. This in…
Nonlocal quantum heat engines made of hybrid superconducting devices
S. Mojtaba Tabatabaei, David Sanchez, Alfredo Levy Yeyati +1
We discuss a quantum thermal machine that generates power from a thermally driven double quantum dot coupled to normal and superconducting reservoirs. Energy exchange between the d…
Nanometer-Scale Nuclear Magnetic Resonance Diffraction with Sub-Ångstrom Precision
Holger Haas, Sahand Tabatabaei, William Rose +9
Achieving atomic resolution is the ultimate limit of magnetic resonance imaging (MRI), and attaining this capability offers enormous technological and scientific opportunities, fro…
Andreev-Coulomb Drag in Coupled Quantum Dots
S. Mojtaba Tabatabaei, David Sanchez, Alfredo Levy Yeyati +1
The Coulomb drag effect has been observed as a tiny current induced by both electron-hole asymmetry and interactions in normal coupled quantum dot devices. In the present work we s…
Lasing in a coupled hybrid double quantum dot-resonator system
S. Mojtaba Tabatabaei, Neda Jahangiri
We theoretically investigate the possibility of lasing in an electromagnetic resonator coupled to a voltage-biased hybrid double quantum dot comprised of a double quantum dot tunne…
Andreev reflection assisted lasing in an electromagnetic resonator coupled to a hybrid-quantum-dot
S. Mojtaba Tabatabaei, Farshad Ebrahimi
A single mode electromagnetic resonator coupled to a two-level hybrid-quantum-dot(hQD) is studied theoretically as a laser(maser), when the hQD is driven out of equilibrium with ex…
Perturbative approach to the capacitive interaction between a sensor quantum dot and a charge qubit
S. Mojtaba Tabatabaei
We consider the capacitive interaction between a charge qubit and a sensor quantum dot(SQD) perturbatively to the second order of their coupling constant at zero temperature by uti…
