Measurement-Induced Phase Transitions and Logical-Space Localization in Floquet Monitored Clifford Circuits

Hyunsoo Ha, David A. Huse

An entanglement transition can occur without a corresponding transition in purification. We demonstrate this separation in spatially local monitored Clifford circuits with a fixed…

Strong-to-Weak Symmetry Breaking in Open Quantum Systems: From Discrete Particles to Continuum Hydrodynamics

Jacob Hauser, Kaixiang Su, Hyunsoo Ha +6

We explore the onset of spontaneous strong-to-weak symmetry breaking (SW-SSB) under U(1)-symmetric (i.e., charge-conserving) open-system dynamics. We define this phenomenon for qua…

Quench spectroscopy of amplitude modes in a one-dimensional critical phase

Hyunsoo Ha, David A. Huse, Rhine Samajdar

We investigate the emergence of an amplitude (Higgs-like) mode in the gapless phase of the D XXZ spin chain. Unlike conventional settings where amplitude modes arise from sp…

Roughening Transition in Quantum Circuits

Hyunsoo Ha, David A. Huse, Grace M. Sommers

We explore a roughening phase transition that occurs in the entanglement dynamics of certain quantum circuits. Viewing entanglement as the free energy of a membrane in a circuit-de…

A theory of quasiballistic spin transport

Jeffrey Z. Song, Hyunsoo Ha, Wen Wei Ho +1

A recent work [Mierzejewski et al., Phys. Rev. B 107, 045134 (2023)] observed "quasiballistic spin transport" - long-lived and transiently ballistic modes of the magnetization dens…

Absorbing state transitions with discrete symmetries

Hyunsoo Ha, David A. Huse, Rhine Samajdar

Robust phases of matter, which remain stable under small perturbations, are of fundamental importance in statistical physics and quantum information. Recent advances in interactive…

Hydrodynamics of spin transport in the Haldane-Shastry chain

Vir B. Bulchandani, Hyunsoo Ha

We use kinetic theory and the thermodynamic Bethe ansatz to derive the hydrodynamics of spin transport in the Haldane-Shastry chain. We obtain analytical expressions for relaxation…

Measurement-induced phase transitions in systems with diffusive dynamics

Hyunsoo Ha, Akshat Pandey, Sarang Gopalakrishnan +1

The competition between scrambling and projective measurements can lead to measurement-induced entanglement phase transitions (MIPT). In this work, we show that the universality cl…
