Coulomb blockade in a non-thermalized quantum dot
George McArdle, Rose Davies, Igor V. Lerner +1
We investigate non-equilibrium transport properties of a quantum dot in the Coulomb blockade regime under the condition of negligible inelastic scattering during the dwelling time…
Coulomb staircase in an asymmetrically coupled quantum dot
George McArdle, Rose Davies, Igor V. Lerner +1
We investigate the Coulomb blockade in quantum dots asymmetrically coupled to the leads for an arbitrary voltage bias focusing on the regime where electrons do not thermalise durin…
Electron-Phonon Decoupling in Two Dimensions
George McArdle, Igor V. Lerner
In order to observe many-body localisation in electronic systems, decoupling from the lattice phonons is required, which is possible only in out-of-equilibrium systems. We show tha…
The Interplay of Charge and Spin in Quantum Dots: The Ising Case
Boaz Nissan-Cohen, Yuval Gefen, Mikhail N. Kiselev +1
The physics of quantum dots is succinctly depicted by the {\it Universal Hamiltonian}, where only zero mode interactions are included. In the case where the latter involve charging…
Quantum transport thermometry for electrons in graphene
K. Kechedzhi, D. W. Horsell, F. V. Tikhonenko +4
We propose a method of measuring the electron temperature in mesoscopic conductors and demonstrate experimentally its applicability to micron-size graphene devices in the lin…
Low temperature decoherence and relaxation in charge Josephson-junction qubits
Alex Grishin, Igor V. Yurkevich, Igor V. Lerner
In this lectures, we have described some essential features of loss of coherence by a qubit coupled to the environment. We have first presented well known semiclassical arguments t…
Tunnelling density of states at Coulomb blockade peaks
Nicholas Sedlmayr, Igor V. Yurkevich, Igor V. Lerner
We calculate the tunnelling density of states (TDoS) for a quantum dot in the Coulomb blockade regime, using a functional integral representation with allowing correctly for the ch…
Low-Temperature Decoherence of Qubit Coupled to Background Charges
Alex Grishin, Igor V. Yurkevich, Igor V. Lerner
We have found an exact expression for the decoherence rate of a Josephson charge qubit coupled to fluctuating background charges. At low temperatures the decoherence rate i…
Nonlinear Sigma Model for Normal and Superconducting Systems: A Pedestrian Approach
Igor V. Lerner
The nonlinear sigma model (NLSM) epitomises a field-theoretical approach to (interacting) electrons in disordered media. These lectures are aimed at the audience who might have vag…
Anderson Orthogonality Catastrophe in Disordered Systems
Yuval Gefen, Richard Berkovits, Igor V. Lerner +1
We study the Anderson orthogonality catastrophe (AOC) in finite conductors with diffusive disorder. The disorder averaged logarithm of , the overlap between the ground states be…
Can the trace formula describe weak localisation?
Robert S. Whitney, Igor V. Lerner, Robert A. Smith
We attempt to systematically derive perturbative quantum corrections to the Berry diagonal approximation of the two-level correlation function (TLCF) for chaotic systems. To this e…
Spectral statistics in disordered metals: a trajectories approach
Robert A. Smith, Igor V. Lerner, Boris L. Altshuler
We show that the perturbative expansion of the two-level correlation function, , in disordered conductors can be understood semiclassically in terms of self-intersecting part…
