We study Majorana chain with the shortest possible interaction term and in the presence of
hop** alternation. When formulated in terms of spins the model corresponds to the …

The cluster mean-field with density matrix renormalization (CMFT+ DMRG) method which
combines the simplicity of the mean-field theory and the numerical power of the density …

We study the effect of antiferromagnetic longitudinal coupling on the one-dimensional
transverse field Ising model with nearest-neighbor couplings. In the topological phase …

Here we present experimental evidence of the pseudo-doublet ground state of the non-
Kramers compound SrTm2O4, based on specific heat, magnetic entropy and electron …

The phase diagram of the quantum Axial Next-Nearest Neighbour Ising model is studied
with and without transverse field, in order to locate the maximally frustrated point …

The thesis contains theoretical study of number of systems in low dimension, which are
related to quantum Ising model. The main results are emergence of Majorana fermions in …
