Entanglement Spectrum Resolved by Loop Symmetries
Haruki Yagi, Zongping Gong
A rigorous analysis is presented for the entanglement spectrum of quantum many-body states possessing a higher-form group-representation symmetry generated by topological Wilson lo…
Entanglement negativity in free fermions: twisted characteristic polynomial, universal bounds, and area laws
Ryota Matsuda, Zongping Gong
We present a general and simple formula for computing the entanglement negativity in free fermions. Our formula allows for deriving several universal bounds on negativity and its r…
Optimal spectral transport of non-Hermitian systems
Mingtao Xu, Zongping Gong, Wei Yi
The optimal transport problem seeks to minimize the total transportation cost between two distributions, thus providing a measure of distance between them. In this work, we study t…
Threefold Way for Typical Entanglement
Haruki Yagi, Ken Mochizuki, Zongping Gong
A typical quantum state with no symmetry can be realized by letting a random unitary act on a fixed state, and the subsystem entanglement spectrum follows the Laguerre unitary ense…
Any Quantum Many-Body State under Local Dissipation will be Disentangled in Finite Time
Zongping Gong, Yuto Ashida
We prove that any quantum many-spin state under genetic local dissipation will be fully separable after a finite time independent of the system size. Such a sudden death of many-bo…
Quantum Dynamical Tunneling Breaks Classical Conserved Quantities
Lingchii Kong, Zongping Gong, Biao Wu
We discover that quantum dynamical tunneling, occurring between phase space regions in a classically forbidden way, can break conserved quantities in pseudointegrable systems. We r…
