Friction force: from mechanics to thermodynamics
Christian Ferrari, Christian Gruber
We study some mechanical problems in which a friction force is acting on the system. Using the fundamental concepts of state, time evolution and energy conservation we explain how…
Entanglement, which-way measurements, and a quantum erasure
Christian Ferrari, Bernd Braunecker
We present a didactical approach to the which-way experiment and the counterintuitive effect of the quantum erasure for one-particle quantum interferences. The fundamental concept…
Resonances Width in Crossed Electric and Magnetic Fields
Christian Ferrari, Hynek Kovarik
We study the spectral properties of a charged particle confined to a two-dimensional plane and submitted to homogeneous magnetic and electric fields and an impurity potential. We u…
On the Exponential Decay of Magnetic Stark Resonances
Christian Ferrari, Hynek Kovarik
We study the time decay of magnetic Stark resonant states. As our main result we prove that for sufficiently large time these states decay exponentially with the rate given by the…
Extended Edge States in Finite Hall Systems
Christian Ferrari, Nicolas Macris
We study edge states of a random Schroedinger operator for an electron submitted to a magnetic field in a finite macroscopic two dimensional system of linear dimensions equal to L.…
Spectral Properties of Finite Quantum Hall Systems
Christian Ferrari, Nicolas Macris
In this note we review spectral properties of magnetic random Schroedinger operators H_omega=H_0+V_omega + U_l + U_r defined on L^2(R x [-L/2,L/2],dx dy) with periodic boundary con…
