Emergence of a molecular quantum liquid in one dimension
Rajashri Parida, Biswajit Paul, Harish S. Adsule +4
We investigate the fate of a one-dimensional lattice superfluid formed by hard-core bosons, aka `atoms' (alternatively, a free spinless Fermi sea) subjected to nearest-neighbor att…
Engineering edge states in two-leg SSH ladder and their topoelectric circuit realization
Anish Kuanr, Rajashri Parida, Saralasrita Mohanty +2
We study the topological phase transition in a two-leg Su-Schrieffer-Heeger (SSH) ladder by redefining the unit-cell structure. For both identical hopping dimerization pattern (uni…
Coupling induced emergent topology in a two-leg fermionic ladder
Rajashri Parida, Biswajit Paul, Soumya Ranjan Padhi +1
We investigate the ground state properties of spinless fermions on a two leg ladder, by allowing the nearest-neighbour hopping dimerization in one leg and uniform hopping in the ot…
Topological phase transition through tunable nearest-neighbor interactions in a one-dimensional lattice
Rajashri Parida, Diptiman Sen, Tapan Mishra
We investigate the phase diagram of a one-dimensional model of hardcore bosons or spinless fermions with tunable nearest-neighbor interactions. By introducing alternating repulsive…
Reentrant topology and reverse pumping in a quasiperiodic flux ladder
Sanchayan Banerjee, Rajashri Parida, Tapan Mishra
Topological phases of matter are known to be unstable against strong onsite disorder in one dimension. In this work, however, we propose that in the case of a topological ladder, a…
Interaction driven topological phase transitions of hardcore bosons on a two-leg ladder
Rajashri Parida, Ashirbad Padhan, Tapan Mishra
We investigate the topological properties of hardcore bosons possessing nearest-neighbor repulsive interactions on a two-leg ladder. We show that by allowing nearest neighbour dime…
