Dissipative quantum mechanics and Kondo-like impurities on noncommutative two-tori

Patrizia Iacomino, Vincenzo Marotta, Adele Naddeo

In a recent paper, by exploiting the notion of Morita equivalence for field theories on noncommutative tori and choosing rational values of the noncommutativity parameter (in a…

One-loop Effective Action of the Holographic Antisymmetric Wilson Loop

Alberto Faraggi, Wolfgang Mueck, Leopoldo A. Pando Zayas

We systematically study the spectrum of excitations and the one-loop determinant of holographic Wilson loop operators in antisymmetric representations of supersymme…

An introduction to quantum gravity

Giampiero Esposito

Quantum gravity was born as that branch of modern theoretical physics that tries to unify its guiding principles, i.e., quantum mechanics and general relativity. Nowadays it is pro…

Spectral action, Weyl anomaly and the Higgs-Dilaton potential

A. A. Andrianov, M. A. Kurkov, Fedele Lizzi

We show how the bosonic spectral action emerges from the fermionic action by the renormalization group flow in the presence of a dilaton and the Weyl anomaly. The induced action co…

Non-commutative Einstein equations and Seiberg-Witten map

Paolo Aschieri, Elisabetta Di Grezia, Giampiero Esposito

The Seiberg--Witten map is a powerful tool in non-commutative field theory, and it has been recently obtained in the literature for gravity itself, to first order in non-commutativ…

Second order invariants and holography

Luca Bonanno, Gerardo Iannone, Orlando Luongo

Motivated by recent works on the role of the Holographic principle in cosmology, we relate a class of second order Ricci invariants to the IR cutoff characterizing the holographic…

The Polyakov Loop of Anti-symmetric Representations as a Quantum Impurity Model

Wolfgang Mueck

The Polyakov loop of an operator in the anti-symmetric representation in N=4 SYM theory on spacial R^3 is calculated, to leading order in 1/N and at large 't Hooft coupling, by sol…
