The -motivic Gysin map
Longke Tang
We develop a -unstable non--invariant theory of motivic spaces and spectra, and construct the Gysin map therein for regular immersions. This in particul…
Integrability and quench dynamics in the spin-1 central spin XX model
Long-Hin Tang, David M. Long, Anatoli Polkovnikov +2
Central spin models provide an idealized description of interactions between a central degree of freedom and a mesoscopic environment of surrounding spins. We show that the family…
Momentum space entanglement of interacting fermions
Michael O. Flynn, Long-Hin Tang, Anushya Chandran +1
Momentum space entanglement entropy probes quantum correlations in interacting fermionic phases. It is very sensitive to interactions, obeying volume-law scaling in general, while…
Multi-magnon quantum many-body scars from tensor operators
Long-Hin Tang, Nicholas O'Dea, Anushya Chandran
We construct a family of three-body spin-1/2 Hamiltonians with a super-extensive set of infinitely long-lived multi-magnon states. A magnon in each such state carries either quasi-…
On the Standard Lattices
Rongquan Feng, Longke Tang, Kun Wang
A lattice in the Euclidean space is standard if it has a basis consisting vectors whose norms equal to the length in its successive minima. In this paper, it is shown that with the…
