Singularities of the Partition Function for the Ising Model Coupled to 2d Quantum Gravity [PDF]

, 1997
We study the zeros in the complex plane of the partition function for the Ising model coupled to 2d quantum gravity for complex magnetic field and real temperature, and for complex temperature and real magnetic field, respectively.

An efficient algorithm for critical plane factors evaluation

International Journal of Mechanical Sciences, 2023
Fatigue of structural components is a widely discussed subject on which extensive research is still being carried out, both in the scientific and industrial communities. Fatigue damage still represents a major issue for both metallic and non-metallic components, sometimes leading to unforeseen failures for in-service parts.

Fatigue assessment of a FSAE car rear upright by a closed form solution of the critical plane method

Fracture and Structural Integrity
Material fatigue is extensively discussed and researched within scientific and industrial communities. Fatigue damage poses a significant challenge for both metallic and non-metallic components, often resulting in unexpected failures of in-service parts.

Anomalous Superconducting Properties and Field Induced Magnetism in CeCoIn5

, 2001
In the heavy fermion superconductor CeCoIn5 (Tc=2.3K) the critical field is large, anisotropic and displays hysteresis. The magnitude of the critical-field anisotropy in the a-c plane can be as large as 70 kOe and depends on orientation.

Partition function zeros of the Q-state Potts model on the simple-cubic lattice

, 2002
The $Q$-state Potts model on the simple-cubic lattice is studied using the zeros of the exact partition function on a finite lattice. The critical behavior of the model in the ferromagnetic and antiferromagnetic phases is discussed based on the ...
