Simultaneous Sequential Detection of Multiple Interacting Faults
Ram Rajagopal, XuanLong Nguyen, Sinem Coleri Ergen +1
Single fault sequential change point problems have become important in modeling for various phenomena in large distributed systems, such as sensor networks. But such systems in man…
Pseudoduality and Complex Geometry in Sigma Models
Mustafa Sarisaman
We study the pseudoduality transformations in two dimensional N = (2, 2) sigma models on Kähler manifolds. We show that structures on the target space can be transformed into the p…
Born-Infeld Axion-Dilaton Electrodynamics and Electromagnetic Confinement
D. A. Burton, T. Dereli, R. W. Tucker
A generalization of Born-Infeld non-linear vacuum electrodynamics involving axion and dilaton fields is constructed with couplings dictated by electromagnetic duality and SL(2,R) s…
Mean-field theory for the Mott insulator-paired superfluid transition in the two-species Bose-Hubbard model
M. Iskin
The standard mean-field theory for the Mott insulator-superfluid phase transition is not sufficient to describe the Mott insulator-paired superfluid phase transition. Therefore, by…
Tensor Renormalization Group: Local Magnetizations, Correlation Functions, and Phase Diagrams of Systems with Quenched Randomness
Can Güven, Michael Hinczewski, A. Nihat Berker
The tensor renormalization-group method, developed by Levin and Nave, brings systematic improvability to the position-space renormalization-group method and yields essentially exac…
Isothermal sweep theorems for ultra-cold quantum gases in a canonical ensemble
M. Iskin
After deriving the isothermal Hellmann-Feynman theorem (IHFT) that is suitable for mixed states in a canonical ensemble, we use this theorem to obtain the isothermal magnetic-field…
