Teaching ideal quantum measurement, from dynamics to interpretation

Armen E. Allahverdyan, Roger Balian, Theo M. Nieuwenhuizen

We present a graduate course on ideal measurements, analyzed as dynamical processes of interaction between the tested system S and an apparatus A, described by quantum statistical…

The most likely common cause

A. Hovhannisyan, A. E. Allahverdyan

The common cause principle for two random variables and is examined in the case of causal insufficiency, when their common cause is known to exist, but only the joint p…

Determining a quantum state by means of a single apparatus

A. E. Allahverdyan, R. Balian, Th. M. Nieuwenhuizen

The unknown state $\hrho$ of a quantum system S is determined by letting it interact with an auxiliary system A, the initial state of which is known. A one-to-one mapping can thus…

Reply on Comment on ``Extraction of work from a single thermal bath in the quantum regime''

A. E. Allahverdyan, Th. M. Nieuwenhuizen

In our recent letter [1] we discussed that thermodynamics is violated in quantum Brownian motion beyond the weak coupling limit. In his comment, Tasaki [2] derives an inequality fo…

Singularites at a Dense Set of Temperature in Husimi Tree

A. E. Alahverdian, N. S. Ananikian, S. K. Dallakian

We investigate complex temperature singularities of the three-site interacting Ising model on the Husimi tree in the presentce of magnetic field. We show that at certain magnetic f…
