Emerging exceptional point with breakdown of skin effect in non-Hermitian systems
Sayan Jana, Lea Sirota
We study the interplay of two distinct non-Hermitian parameters: directional coupling and onsite gain-loss, together with topology, in coupled one-dimensional (1D) non-Hermitian Su…
Gravitational lensing and tunneling of mechanical waves in synthetic curved spacetime
Sayan Jana, Lea Sirota
Black holes are considered among the most fascinating objects that exist in our universe, since in the classical formalism nothing, even no light, can escape from their vicinity du…
Mapping the energy-time landscape of spins with helical X-rays
N. Pontius, J. K. Dewhurst, C. Schuessler-Langeheine +5
Unveiling the key mechanisms that determine optically driven spin dynamics is essential both to probe the fundamental nature of ultrafast light-matter interactions, but also to dri…
Non-local spin entanglement in a fermionic chain
Sayan Jana, Anant V. Varma, Arijit Saha +1
An effective two-spin density matrix (TSDM) for a pair of spin- degree of freedom, residing at a distance of in a spinful Fermi sea, can be obtained from the two-electron…
Emergence of exceptional points and their spectroscopic signature in Dirac semimetal-dirty Superconductor heterojunction
Sayan Jana, Debashree Chowdhury, Arijit Saha
We theoretically investigate the emergence of non-hermitian physics at the heterojunction of a type-II Dirac semi-metal (DSM) and a dirty superconductor (DSC). The non-hermiticity…
Tailoring Metal Insulator Transitions Band Topology via Off-resonant Periodic Drive in an Interacting Triangular Lattice
Sayan Jana, Priyanka Mohan, Arijit Saha +1
A triangular lattice with onsite Coulomb interaction present only on one sub-lattice, is periodically driven by electromagnetic field with a frequency at half fil…
Impact of strong correlations on a band topological insulator on the Lieb lattice
Sayan Jana, Arijit Saha, Anamitra Mukherjee
The Lieb lattice possesses three bands and with intrinsic spin orbit coupling , supports topologically non-trivial band insulating phases. At half filling the lower band is full…
Jackiw-Rebbi zero modes in non-uniform topological insulator nanowire
Sayan Jana, Arijit Saha, Sourin Das
We theoretically investigate the emergence of Jackiw-Rebbi zero modes and their conductance signature in non-uniform topological insulator nano-wires. We modelled the non-uniform n…
