Quantum statistics in an extended collider coupled to a qubit
Rishav Chaudhuri, Sai Satyam Samal
Mesoscopic colliders provide an effective platform for probing the mutual statistics of quantum particles. Recent experiments have successfully extracted the mutual statistics of f…
Krylov complexity and fidelity susceptibility in two-band Hamiltonians
Rishav Chaudhuri, Ayush Raj, Soham Ray +1
We investigate Krylov spread complexity for the ground state of two-band Hamiltonians, where the reference state is a generic state on the Bloch sphere. The spread complexity is ob…
Symmetry and Topology in a Non-Hermitian Kitaev chain
Ayush Raj, Soham Ray, Sai Satyam Samal
We investigate the non-Hermitian Kitaev chain with non-reciprocal hopping amplitudes and asymmetric superconducting pairing. We work out the symmetry structure of the model and sho…
Quantum statistics and self-interference in extended colliders
Sai Satyam Samal, Smitha Vishveshwara, Yuval Gefen +1
Collision of quantum particles remains an effective way of probing their mutual statistics. Colliders based on quantum point contacts in quantum Hall edge states have been successf…
Topological entanglement entropy meets holographic entropy inequalities
Joydeep Naskar, Sai Satyam Samal
Topological entanglement entropy (TEE) is an efficient way to detect topological order in the ground state of gapped Hamiltonians. The seminal work of Kitaev and Preskill~\cite{pre…
Subsubleading soft graviton symmetry and MHV graviton scattering amplitudes
Shamik Banerjee, Sudip Ghosh, Sai Satyam Samal
In arXiv:2008.04330 it was shown that supertranslation and current algebra symmetries, corresponding to leading and subleading soft graviton theorems,…
Non-linear transport without spin-orbit coupling or warping in two-dimensional Dirac semimetals
Sai Satyam Samal, S. Nandy, Kush Saha
It has recently been realized that the first-order moment of the Berry curvature, namely the Berry curvature dipole (BCD) can give rise to non-linear current in a wide variety of t…
