One-Sign Order Parameter in Iron Based Superconductor
The onset of superconductivity at the transition temperature is marked by the onset of order, which is characterized by an energy gap. Most models of the iron-based superconductors find a sign-changing (s±) order parameter [1-6], with the physical implication that pairing is driven by spin fluctuations. Recent work, however, has indicated that LiFeAs has a simple isotropic order parameter [7-9]...
متن کاملGlassiness and exotic entropy scaling induced by quantum fluctuations in a disorder-free frustrated magnet
When spins are arranged in a lattice of triangular motif, the phenomenon of frustration leads to numerous energetically equivalent ground states, and results in exotic states such as spin liquid and spin ice. Here we report an alternative situation: a system, classically a liquid, freezes in the clean limit into a glassy state induced by quantum fluctuations. We call such glassy state a spin ja...
متن کاملComplexity as the driving force for glassy transitions
The glass transition is considered within two toys models, a mean field spin glass and a directed polymer in a correlated random potential. In the spin glass model there occurs a dynamical transition, where the the system condenses in a state of lower entropy. The extensive entropy loss, called complexity or information entropy, is calculated by analysis of the metastable (TAP) states. This yie...
متن کاملInhomogeneous low frequency spin dynamics in La(1.65)Eu(0.2)Sr(0.15)CuO(4).
We report Cu and La nuclear magnetic resonance measurements in the title compound that reveal an inhomogeneous glassy behavior of the spin dynamics. A low temperature peak in the La spin lattice relaxation rate and the "wipeout" of Cu intensity both arise from these slow electronic spin fluctuations that reveal a distribution of activation energies. Inhomogeneous slowing of spin fluctuations ap...
متن کاملQuantum Monte Carlo study of the infinite-range Ising spin glass in a transverse field
We study the zero-temperature behaviour of the infinite-ranged Ising spin glass in a transverse field. Using spin summation and Monte Carlo methods we characterize the zerotemperature quantum transition. Our results are well compatible with a value ν = 4 for the correlation length exponent, z = 4 for the dynamical exponent and an algebraic decay t−1 for the imaginary-time correlation function. ...
