On Two-Loop Effective Action of 2D Sigma Model
P. V. Akacevich, A. V. Ivanov
In this paper, we study two-loop contribution to the effective action of a two-dimensional sigma model. We derive a new formula, which can be applicable to a regularization of gene…
Anomaly inflow for local boundary conditions
A. V. Ivanov, D. V. Vassilevich
We study the -invariant of a Dirac operator on a manifold with boundary subject to local boundary conditions with the help of heat kernel methods. In even dimensions, we relate…
Formula for two-loop divergent part of 4-D Yang-Mills effective action
A. V. Ivanov, N. V. Kharuk
In the paper, we study the two-loop contribution to the effective action of the four-dimensional quantum Yang-Mills theory. We derive a new formula for the contribution in terms of…
Extension of the Nakajima-Zwanzig approach to multitime correlation functions of open systems
Anton Ivanov, Heinz-Peter Breuer
We extend the Nakajima-Zwanzig projection operator technique to the determination of multitime correlation functions of open quantum systems. The correlation functions are expresse…
Quantum corrections of the truncated Wigner approximation applied to an exciton transport model
Anton Ivanov, Heinz-Peter Breuer
We modify the path integral representation of exciton transport in open quantum systems such that an exact description of the quantum fluctuations around the classical evolution of…
Bosonic transport through a chain of quantum dots
Anton Ivanov, Georgios Kordas, Andreas Komnik +1
The particle transport through a chain of quantum dots coupled to two bosonic reservoirs is studied. For the case of reservoirs of non-interacting bosonic particles, we derive an e…
