Spin glasses at imaginary temperature
D. B. Saakian
We consider spherical p-spin glass and p-spin glass models at imaginary temperatures. Imaginary temperatures are special case, when order parameters are real value numbers. Here th…
Imitation of 2d quantum field theory by means of REM like models
D. B. Saakian
An imitation of 2d field theory is formulated by means of a model on the hierarchic tree (with branching number close to one) with the same potential and the free correlators ident…
8 levels of harmony and 8 concepts of Complex Systems
D. B. Saakian
A set of general physical principles is proposed as the structural basis for the theory of complex systems. First the concept of harmony is analyzed and its different aspects are u…
The harmony, reflection and other principles of complex systems
D. B. Saakian
A set of general physical principles is proposed as the structural basis for the theory of complex systems. First the concept of harmony is analyzed and its different aspects are u…
Multiscaling at ferromagnetic-spin glass transition point of Random Energy Model and complexity
D. B. Saakian
We calculate moments of free energy's finite size correction for the transition point between ferromagnetic and spin glass phases. We find, that those moments scale with the number…
Ultrametric space cut instead of 2d one in 2d quantum field models
D. B. Saakian
It is possible to formulate 2d field theory on the ultrametric space with the free correlators identical to 2d correlators and the same potential. Such model should carry some feat…
