Rational Control of Magnonic and Electronic Band Splittings
Subhadeep Bandyopadhyay, Anoop Raj, Philippe Ghosez +2
We provide a theoretical demonstration of controllable non-relativistic spin splitting in both electronic and magnonic bands via targeted structural distortions tied to specific ph…
Tomonaga-Luttinger liquid and quantum criticality in spin-1/2 antiferromagnetic Heisenberg chain C14H18CuN4O10 via Wilson ratio
Sharath Kumar Channarayappa, Sankalp Kumar, N. S. Vidhyadhiraja +9
The ground state of a one-dimensional spin-1/2 uniform antiferromagnetic Heisenberg chain (AfHc) is a Tomonaga-Luttinger liquid which is quantum-critical with respect to applied ma…
Transverse resistance due to electronic inhomogeneities in superconductors
Shamashis Sengupta, Alireza Farhadizadeh, Joe Youssef +8
Phase transitions in many-body systems are often associated with the emergence of spatial inhomogeneities. Such features may develop at microscopic lengthscales and are not necessa…
A theorem on extensive ground state entropy, spin liquidity and some related models
Sumiran Pujari
An exact mechanism is written down to guarantee extensive residual ground state entropy and spin liquidity in spin-1/2 lattice models with bond-dependent couplings. It is based on…
A Class of Exactly Solvable Hamiltonians for S=1/2 Quantum Magnets with Spinless Fermionic Excitations in Higher Dimensions
Sumiran Pujari
This contribution summarizes the main results of a work on exactly solvable Hamiltonians for quantum magnets. A class of Hamiltonians which supports fractionalized spinless fermion…
A solvable embedding mechanism for one-dimensional spinless and Majorana fermions in higher-dimensional spin-1/2 magnets
Sumiran Pujari
We write down a class of two-dimensional quantum spin-1/2 Hamiltonians whose eigenspectra are exactly solvable via the Jordan-Wigner transformation. The general structure correspon…
(H,Li)RuO : a possible zero-field Ru-based Kitaev Quantum Spin Liquid
Sanjay Bachhar, M. Baenitz, Hubertus Luetkens +3
We report the synthesis and properties of (H,Li)RuO, which is shown to be a system made out of Ru moments in a honeycomb geome…
