Gapless points of dimerized quantum spin chains: analytical and numerical studies
V. Ravi Chandra, Diptiman Sen, Naveen Surendran
We study the locations of the gapless points which occur for quantum spin chains of finite length (with a twisted boundary condition) at particular values of the nearest neighbor d…

Infinite-range Ising ferromagnet in a time-dependent transverse field: quench and ac dynamics near the quantum critical point
Arnab Das, K. Sengupta, Diptiman Sen +1
We study an infinite range ferromagnetic Ising model in the presence of a transverse magnetic field which exhibits a quantum paramagnetic-ferromagnetic phase transition at a critic…
