Quantum-Geometric Length Scale for Long-distance Squeezing in Bosonic Bogoliubov Systems
Sonu Verma, Sangmo Cheon, Myung-Joong Hwang +1
Multimode squeezing is a key resource for continuous-variable quantum technologies, but its spatial range in bosonic lattices is usually tied to dispersive propagation. Here we sho…

Boundary-Driven Complex Brillouin Zone in Non-Hermitian Electric Circuits
Yung Kim, Sonu Verma, Minwook Kyung +5
Complex-valued physical quantities, often non-conserved, represent key phenomena in non-Hermitian systems such as dissipation and localization. Recent advancements in non-Hermitian…

Non-Bloch band theory of sub-symmetry-protected topological phases
Sonu Verma, Moon Jip Park
Bulk-boundary correspondence (BBC) of symmetry-protected topological (SPT) phases relates the non-trivial topological invariant of the bulk to the number of topologically protected…
