Tight-binding dispersion of the prismatic pentagonal lattice
Susobhan Paul, Asim Kumar Ghosh
Tight-binding Hamiltonian on the prismatic pentagonal lattice is exactly solved to obtain the analytic expressions of dispersion relations and eigenvectors. This lattice is made of…

Thermally stable multipartite entanglements in the frustrated Heisenberg hexagon
Moumita Deb, Asim Kumar Ghosh
Thermally stable quantum states with multipartite entanglements led by frustration are found in the antiferromagnetic spin-1/2 Heisenberg hexagon. The model has been solved exactly…

Field-induced disorder in a gapped spin system with non-magnetic impurities
H. -J. Mikeska, Asimkumar Ghosh, A. K. Kolezhuk
We study S=1/2 dimers which are weakly coupled by three-dimensional antiferromagnetic interactions J'. It is commonly known that doping with non-magnetic impurities immediately ind…
