International Symposium on Intertwined Order and Fluctuations in Quantum Materials
International Symposium Intertwined Order and Fluctuations in Quantum Materials
2017/1/12
Understanding quantum materials is one of the major outstanding challenges of contemporary condensed matter physics, with implications for both technology and fundamental science. A ubiquitous feature...
Percolation in Interdependent and Interconnected Networks: Abrupt Change from Second to First Order Transition
Cascading failures, Percolation, Coupled networks, Phase transition
2011/6/21
Robustness of two coupled networks system has been studied only for dependency coupling (S. Buldyrev et. al., Nature, 2010) and only for connectivity coupling (E. A. Leicht and R. M. D’Souza, arxiv:09...
Diagnosing Deconfinement and Topological Order
Diagnosing Deconfinement Topological Order
2010/11/30
Topological or deconfined phases are characterized by emergent, weakly fluctuating, gauge fields. In condensed matter settings they inevitably come coupled to excitations that carry the corresponding...
Knotting and higher order linking in physical systems
Knotting higher order linking physical systems
2010/10/28
We discuss physical systems with topologies more complicated than simple gaussian linking. Our examples of these higher topologies are in non-relativistic quantum mechanics and in QCD.
Emergence of Complex Spatio-Temporal Order in Nonlinear Field Theories
Phase transitions Solitons Symmetry breaking Nucleation
2006/12/31
We investigate the emergence of time-dependent nonperturbative configurations during the evolution of nonlinear scalar field models with symmetric and asymmetric double-well potentials. Complex spatio...
On the One-loop Yukowa Coupling Beta Function to Order Yg2 in a General a Gauge and Its Gauge Indepence
one-loop Yukawa Gauge Indepence Order Yg2
1997/6/30
We present the calculation of the one-loop Yukawa coupling beta function to order Yg2 in a general a gauge, where Y and g are Yukawa and gauge couplings. We show explicitly how the gauge parameter a c...
A Mean Field Model With Two Order Parameters for Three-Phase Coexistence Near the Tricritical Point
Two Order Parameters Three-Phase Coexistence Tricritical Point
1996/6/30
This study gives a mean field model with two order parameters for three-phase coexistence near the multicritical point. The critical exponents calculated from our model are the tricritical exponents f...
