Exact Criterion for Ground-State Overlap Dominance after Quantum Quenches
Taisanul Haque
It was recently conjectured and verified for the transverse-field Ising model [Phys. Rev. B 113, 165102 (2026)] that, after a sudden quench within the same equilibrium phase, the i…
Nontrivial bounds on extractable energy in quantum energy teleportation for gapped manybody systems with a unique ground state
Taisanul Haque
We establish an exponentially decaying upper bound on the average energy that can be extracted in quantum energy teleportation (QET) protocols executed on finite-range {gapped} lat…
Aspects of Quantum Energy Teleportation
Taisanul Haque
In this work, we explore quantum energy teleportation (QET) protocols, focusing on their behavior at finite temperatures , in ground and excited states. We analyze the role of enta…
Does Entanglement Correlation in Ground State Guarantee Quantum Energy Teleportation?
Taisanul Haque
Although extraction of energy from the ground state is forbidden, one can utilize Quantum Energy Teleportation (QET) protocol for energy extraction -- a two-step protocol involving…
