On a cepstrum-based speech detector robust to white noise
Sergei Skorik, Frederic Berthommier
We study effects of additive white noise on the cepstral representation of speech signals. Distribution of each individual cepstrum coefficient of speech is shown to depend strongl…
Exactly unsolved problems of interacting 1D fermions
Sergei Skorik
Applications of the integrable system techniques to the non-equilibrium transport problems are discussed. We describe one-dimensional electrons tunneling through a point-like defec…
Comment on ``Exact non-equilibrium transport through point contacts in quantum wires and fractional quantum Hall devices''
Sergei Skorik
Fendley, Ludwig and Saleur [Phys. Rev. B52 (1995) 8934] have obtained an expression for the non-equilibrium current through a constriction in the quantum Hall bar based on the Beth…
Exact non-equilibrium current from the partition function for impurity transport problems
Sergei Skorik
We study the partition functions of quantum impurity problems in the domain of complex applied bias for its relation to the non-equilibrium current suggested by Fendley, Lesage and…
Exact current-current Green functions in strongly correlated 1D systems with impurity
Sergei Skorik
We derive an exact expression for the Kubo conductunce in the Quantum Hall device with the point-like intra-edge backscattering. This involves the calculation of current-current co…
Topics in 2D integrable field theories with boundary interactions
Sergei Skorik
We study different aspects of integrable boundary quantum field theories, focusing mostly on the ``boundary sine-Gordon model'' and its applications to condensed matter physics. Th…
