Flat band and Bulk-Boundary correspondence in a non-Hermitian trimerized lattice model with generic boundary conditions
Supriyo Ghosh, Pijush K. Ghosh, Shreekantha Sil
We consider a Su-Schrieffer-Heeger(SSH)-type trimer model with next-nearest-neighbor(NNN) interaction and balanced loss-gain(BLG) to study the combined effect of lattice symmetries…
Magnetic HIP-NN for spin dynamics in disordered itinerant magnets
Supriyo Ghosh, Yunhao Fan, Sheng Zhang +2
We present a magnetic extension of the Hierarchically Interacting Particle Neural Network (HIP-NN) that enables large-scale simulations of electron-mediated spin dynamics in disord…
Edge states and persistent current in a PT-symmetric extended Su-Schrieffer-Heeger model with generic boundary conditions
Supriyo Ghosh, Pijush K. Ghosh, Shreekantha Sil
We consider a generalization of the Su-Schrieffer-Heeger(SSH) model by including next-nearest neighbour(NNN) interaction and balanced loss-gain(BLG), and subjecting the whole syste…
Quantum Integrability and Chaos in periodic Toda Lattice with Balanced Loss-Gain
Supriyo Ghosh, Pijush K. Ghosh
We consider equal-mass quantum Toda lattice with balanced loss-gain for two and three particles. The two-particle Toda lattice is integrable and two integrals of motion which are i…
