Strong Optical-Optical Avoided Crossings Suppress Thermal Conductivity in Ga-Substituted TlInTe
Sayan Paul, Swapan K Pati
In crystalline solids, avoided crossing between acoustic and optical phonons is widely recognized as an effective mechanism for suppressing lattice thermal conductivity (). Ho…
Thermodynamic origin of medium-entropy stabilization in multicomponent rock-salt oxides
Supriya Ghosal, Swapan Pati, Ashutosh Kumar
High entropy oxides are commonly associated with high configurational entropy ( 1.61R) corresponding to five equimolar cations occupying a crystallographic sublattic…
Localization transitions in an open quasiperiodic ladder
Suparna Sarkar, Soumya Satpathi, Swapan K. Pati
We investigate localization transition in an open quasiperiodic ladder where the quasiperiodicity is described by the Aubry-André-Harper model. While previous studies have shown th…
Phases and phase transtions in one-dimensional alternating mixed spin (1/2-1) chain: effects of frustration and anisotropy
Soumya Satpathi, Suparna Sarkar, Swapan K. Pati
We investigate the phases and phase-transitions in one-dimensional alternating mixed-spin (1/2-1) chain in the presence of both frustration and anisotropy. Frustration is introduce…
Low-Lying Electronic Excitations and Nonlinear Optic Properties of Polymers via Symmetrized Density Matrix Renormalization Group Method
S. Ramasesha, Swapan K. Pati, H. R. Krishnamurthy +2
A symmetrized Density Matrix Renormalization Group procedure together with the correction vector approach is shown to be highly accurate for obtaining dynamic linear and third orde…
DMRG Studies of the Spin-Half Heisenberg System with Dimerization and Frustration
R. Chitra, Swapan K. Pati, H. R. Krishnamurthy +2
Using the density matrix renormalization group technique, we study the ground state phase diagram and other low-energy properties of an isotropic antiferromagnetic spin-half chain…
