Multidimensional persistence behaviour in an Ising system
Anjan Kumar Chandra, Subinay Dasgupta
We consider a periodic Ising chain with nearest-neighbour and -th neighbour interaction and quench it from infinite temperature to zero temperature. The persistence probability…
Floating Phase in 2D ANNNI Model
Anjan Kumar Chandra, Subinay Dasgupta
We investigate whether the floating phase (where the correlation length is infinite and the spin-spin correlation decays algebraically with distance) exists in the temperature()…
Spin-spin Correlation in Some Excited States of Transverse Ising Model
Anjan Kumar Chandra, Subinay Dasgupta
We consider the transverse Ising model in one dimension with nearest-neighbour interaction and calculate exactly the longitudinal spin-spin correlation for a class of excited state…
Floating Phase in 1D Transverse ANNNI Model
Anjan Kumar Chandra, Subinay Dasgupta
To study the ground state of ANNNI chain under transverse field as a function of frustration parameter and field strength , we present here two different perturbative analys…
