High-Precision Thermodynamic and Critical Properties from Tensor Renormalization-Group Flows
Michael Hinczewski, A. Nihat Berker
The recently developed tensor renormalization-group (TRG) method provides a highly precise technique for deriving thermodynamic and critical properties of lattice Hamiltonians. The…
Quantum-Mechanically Induced Asymmetry in the Phase Diagrams of Spin-Glass Systems
C. Nadir Kaplan, A. Nihat Berker
The spin-1/2 quantum Heisenberg model is studied in all spatial dimensions d by renormalization-group theory. Strongly asymmetric phase diagrams in temperature and antiferromagneti…
Excitation Spectrum Gap and Spin-Wave Stiffness of XXZ Heisenberg Chains: Global Renormalization-Group Calculation
Ozan S. Sariyer, A. Nihat Berker, Michael Hinczewski
The anisotropic XXZ spin-1/2 Heisenberg chain is studied using renormalization-group theory. The specific heats and nearest-neighbor spin-spin correlations are calculated thoughout…
Field-Driven Hysteresis of the d=3 Ising Spin Glass: Hard-Spin Mean-Field Theory
Burcu Yücesoy, A. Nihat Berker
Hysteresis loops are obtained in the Ising spin-glass phase in d=3, using frustration-conserving hard-spin mean-field theory. The system is driven by a time-dependent random magnet…
Bose-Einstein condensate in a harmonic trap decorated with Dirac delta functions
Haydar Uncu, Devrim Tarhan, Ersan Demiralp +1
We study Bose-Einstein condensation in a harmonic trap with a dimple potential. We specifically consider the case of a tight and deep dimple potential which is modelled by a Dirac…
Griffiths singularities and algebraic order in the exact solution of an Ising model on a fractal modular network
Michael Hinczewski
We use an exact renormalization-group transformation to study the Ising model on a complex network composed of tightly-knit communities nested hierarchically with the fractal scali…
