Symmetry-Enriched Criticality in a Coupled Spin-Ladder
Suman Mondal, Adhip Agarwala, Tapan Mishra +1
We study a one-dimensional ladder of two coupled XXZ spin chains and identify several distinct gapless symmetry-enriched critical phases. These have the same unbroken symmetries an…
Realizing a symmetry protected topological phase through dimerized interactions
Suman Mondal, Ashirbad Padhan, Tapan Mishra
We show that in a system of one dimensional spinless fermions a topological phase and phase transition can emerge only through interaction. By allowing a dimerized or bond-alternat…
Phases and phase transitions of frustrated hard-core bosons on a triangular ladder
Tapan Mishra, Ramesh V. Pai, Subroto Mukerjee +1
We study hardcore bosons on a triangular ladder at half filling in the presence of a frustrating hopping term and a competing nearest neighbor repulsion which promotes crystall…
Phase diagram of the half-filled one-dimensional t-V-V' model
Tapan Mishra, Juan Carrasquilla, Marcos Rigol
We study the phase diagram of spinless fermions with nearest and next-nearest-neighbor interactions in one dimension utilizing the (finite-size) density-matrix renormalization grou…
