Exact Dynamics of Topological Order Across a CDW--SPT Transition
Pradip Kattel, Yicheng Tang, Natan Andrei
We investigate the nonequilibrium dynamics of a one-dimensional interacting system across a transition from a charge-density-wave (CDW) phase to a symmetry-protected topological (S…
Isospectrality and Operator Complexity
Pradip Kattel, Yicheng Tang, Natan Andrei
We study a pair of exactly solvable, isospectral fermion chains, one strongly interacting and one quadratic, that nevertheless display remarkably different phase structures and ope…
A mean-field description of strong-to-weak symmetry breaking in the monitored Bose-Hubbard model
Yicheng Tang, Pradip Kattel, J. H. Pixley
Strong-to-weak spontaneous symmetry breaking has emerged as a novel form of ordering in monitored and open quantum systems, yet its characterization has so far primarily relied on…
The measurement-induced phase transition in strongly disordered spin chains
Yicheng Tang, Pradip Kattel, Arijeet Pal +2
We investigate the dynamics of strongly disordered spin chains in the presence of random local measurements. By studying the transverse-field Ising model with a site-dependent rand…
What is the topological dual of the XXZ spin Chain?
Yicheng Tang, Pradip Kattel, Natan Andrei
We construct a dual symmetry-protected topological (SPT) Hamiltonian for the symmetric anisotropic spin- Heisenberg chain-a model that has traditionally been us…
Complete Boundary Phase Diagram of the Spin- XXZ Chain with Boundary Fields in the Anti-Ferromagnetic Gapped Regime
Parameshwar R. Pasnoori, Yicheng Tang, Junhyun Lee +3
We consider the spin XXZ chain with diagonal boundary fields and solve it exactly using Bethe ansatz in the gapped anti-ferromagnetic regime and obtain the complete p…
Two Channel Kondo behavior in the quantum XX chain with a boundary defect
Yicheng Tang, Pradip Kattel, J. H. Pixley +1
We demonstrate that a boundary defect in the single spin- quantum chain exhibits two-channel Kondo physics. Due to the presence of the defect, the edge spin fract…
Quantum Zeno Effect in Noisy Integrable Quantum Circuits for Impurity Models
Yicheng Tang, Pradip Kattel, J. H. Pixley +1
We theoretically study the open quantum system dynamics (in the Trotterized limit) of integrable quantum circuits in the presence of onsite dephasing noise with a spin-$\frac{1}{2}…
Edge Spin fractionalization in one-dimensional spin- quantum antiferromagnets
Pradip Kattel, Yicheng Tang, J. H. Pixley +1
We show that a gapped spin- chain with antiferromagnetic (AFM) order exhibits in the thermodynamic limit exponentially localized fractional edge modes when the…
The Kondo effect in the quantum spin chain
Pradip Kattel, Yicheng Tang, J. H. Pixley +1
We investigate the boundary phenomena that arise in a finite-size spin chain interacting through an interaction with a spin impurity located at its edge. Up…
Spin fractionalization and zero modes in the spin- XXZ chain with boundary fields
Parameshwar R. Pasnoori, Yicheng Tang, Junhyun Lee +3
In this work we argue that the antiferromagnetic spin XXZ chain in the gapped phase with boundary magnetic fields hosts fractional spin at its edges. Us…
