Finite temperature crossovers and the quantum Widom line near the Mott transition
J. Vucicevic, H. Terletska, D. Tanaskovic +1
The experimentally established phase diagram of the half-filled Hubbard model features the existence of three distinct finite-temperature regimes, separated by extended crossover r…
Self-Organized Criticality in Glassy Spin Systems Requires a Diverging Number of Neighbors
Juan Carlos Andresen, Zheng Zhu, Ruben S. Andrist +3
We investigate the conditions required for general spin systems with frustration and disorder to display self-organized criticality, a property which so far has been established on…
Universal quantum criticality at the Mott-Anderson transition
M. C. O. Aguiar, V. Dobrosavljevic
We present a large N solution of a microscopic model describing the Mott-Anderson transition on a finite-coordination Bethe lattice. Our results demonstrate that strong spatial flu…
The effect of disorder on quantum phase transition in the double layered ruthenates (Sr1-xCax)3Ru2O7
Zhe Qu, Jin Peng, Tijiang Liu +4
(Sr1-xCax)3Ru2O7 is characterized by complex magnetic states, spanning from a long-range antiferromagnetically ordered state over an unusual heavy-mass nearly ferromagnetic (NFM) s…
Universality of modulation length (and time) exponents
Saurish Chakrabarty, Vladimir Dobrosavljevic, Alexander Seidel +1
We study systems with a crossover parameter lambda, such as the temperature T, which has a threshold value lambda* across which the correlation function changes from exhibiting fix…
