Gapless quantum spin liquid in the triangular system SrCuSbO
S. Kundu, Aga Shahee, Atasi Chakraborty +9
We report gapless quantum spin liquid behavior in the layered triangular SrCuSbO (SCSO) system. X-ray diffraction shows superlattice reflections associated with a…
Colorful points in the XY regime of XXZ quantum magnets
Santanu Pal, Prakash Sharma, Hitesh J. Changlani +1
In the XY regime of the XXZ Heisenberg model phase diagram, we demonstrate that the origin of magnetically ordered phases is influenced by the presence of solvable points with exac…
Bilayer Coulomb phase of two dimensional dimer models: Absence of power-law columnar order
Nisheeta Desai, Sumiran Pujari, K. Damle
We study the fully-packed dimer model on the bilayer square lattice with fugacity equal to () for inter-layer (intra-layer) dimers, and intra-layer interaction between n…
Signatures of a spin-1/2 cooperative paramagnet in the diluted triangular lattice of YCuTiO
S. Kundu, Akmal Hossain, Pranava Keerthi S +11
We present a combination of thermodynamic and dynamic experimental signatures of a disorder driven dynamic cooperative paramagnet in a 50% site diluted triangular lattice spin-1/2…
On the topological character of three-dimensional Nexus triple point degeneracies
Ankur Das, Sumiran Pujari
Recently a generic class of three-dimensional band structures was identified that host two-fold line degeneracies meeting at three-fold or triple point degeneracies, which resist t…
Symmetry protection and giant Fermi arcs from multifold fermions in binary, ternary, and quaternary compounds
Chanchal K. Barman, Chiranjit Mondal, Sumiran Pujari +2
Higher-fold chiral fermions that go beyond two-fold Weyl fermions have recently been reported in crystalline systems. Here, we focus on such excitations in several binary, ternary…
