Abelian and non-Abelian geometric phases in adiabatic open quantum systems
M. S. Sarandy, D. A. Lidar
We introduce a self-consistent framework for the analysis of both Abelian and non-Abelian geometric phases associated with open quantum systems, undergoing cyclic adiabatic evoluti…
Quantum Phase Transitions and Bipartite Entanglement
Lian-Ao Wu, Marcelo S. Sarandy, Daniel A. Lidar
We develop a general theory of the relation between quantum phase transitions (QPTs) characterized by nonanalyticities in the energy and bipartite entanglement. We derive a functio…
Consistency of the Adiabatic Theorem
M. S. Sarandy, L. -A. Wu, D. A. Lidar
We review the quantum adiabatic approximation for closed systems, and its recently introduced generalization to open systems (M.S. Sarandy and D.A. Lidar, e-print quant-ph/0404147)…
Adiabatic approximation in open quantum systems
M. S. Sarandy, D. A. Lidar
We generalize the standard quantum adiabatic approximation to the case of open quantum systems. We define the adiabatic limit of an open quantum system as the regime in which its d…
Nonrenormalization theorems for N=2 Super Yang-Mills
V. E. R. Lemes, N. Maggiore, M. S. Sarandy +3
The BRST algebraic proofs of the the nonrenormalization theorems for the beta functions of N=2 and N=4 Super Yang-Mills theories are reviewed.
