We consider a biased quantum point contact between two Luttinger liquids measuring a quantum-mechanical system (oscillator). There are three main physical results. First, we find that for voltages higher than the oscillator level spacing, the effect of the measurement is equivalent to coupling to a heat bath, with an effective temperature that only depends on the device $I\ensuremath{-}V$ characteristic. Second, we find that this heating changes the $I\ensuremath{-}V$ characteristics on the… 
Nonequilibrium quantum dissipation in spin-fermion systems
Dissipative processes in nonequilibrium many-body systems are fundamentally different than their equilibrium counterparts. Such processes are of great importance for the understanding of relaxation
Chain-boson model for the decoherence and relaxation of a few coupled SQUIDs in a phonon bath
We develop a "chain-boson model" master equation, within the Born-Markov approximation, for a few superconducting quantum interference devices (SQUIDs) coupled into a chain and exchanging their
Shot noise of a tunnel junction displacement detector
We study quantum-mechanically the frequency-dependent current noise of a tunnel-junction coupled to a nanomechanical oscillator. The cases of both dc and ac voltage bias are considered, as are the
Spin Dynamics in a Tunnel Junction between Ferromagnets
The dynamics of a single spin embedded in the tunnel junction (quantum point contact) between ferromagnets is addressed. Using the Keldysh technique, we derive a quantum Langevin equation. As a
Molecular transport junctions: vibrational effects
Transport of electrons in a single molecule junction is the simplest problem in the general subject area of molecular electronics. In the past few years, this area has been extended to probe beyond

Quantum-classical transition induced by electrical measurement.
TLDR
A model of an electrical tunnel junction coupled to a mechanical system (oscillator) is studied to simulate the dephasing effect of measurement on a quantum system and it is found that the oscillator dynamics becomes damped, with the effective temperature determined by the voltage drop across the junction.
Tunneling and quantum noise in one-dimensional Luttinger liquids.
TLDR
Non-equilibrium noise in the transmission current through barriers in 1-D Luttinger liquids and in the tunneling current between edges of fractional quantum Hall liquids is studied and it is shown that contributions from terms of order higher than the dipole-dipole interaction should only affect the strength of the $|\omega|$ singularity.
Coherent control of macroscopic quantum states in a single-Cooper-pair box
A nanometre-scale superconducting electrode connected to a reservoir via a Josephson junction constitutes an artificial two-level electronic system: a single-Cooper-pair box. The two levels consist
Transport in a one-channel Luttinger liquid.
TLDR
It is shown that for repulsive electron interactions, the electrons are completely reflected by even the smallest scatterer, leading to a truly insulating weak link, in striking contrast to that for noninteracting electrons.
CONTINUOUS QUANTUM MEASUREMENT OF A DOUBLE DOT
We consider the continuous measurement of a double quantum dot by a weakly coupled detector ~tunnel point contact nearby!. While the conventional approach describes the gradual system decoherence due
Measurements with a noninvasive detector and dephasing mechanism
We study the dynamics of the measurement process in quantum-dot systems, where a particular state out of coherent superposition is observed. The ballistic point contact placed near one of the dots is

TLDR
An exact mapping between two-dimensional quantum Hall systems and one-dimensional electron models is found and a narrow-band noise is found in the dc transport of the FQH states, which can be used to directly measure the fractional charge of the quasiparticles.
