Post-selected Criticality in Measurement-induced Phase Transitions
Dolly Nambi, Kabir Khanna, Andrew Allocca +4
Information-theoretic phase transitions, such as the measurement-induced phase transition (MIPT), characterize the robustness of quantum dynamics to local monitoring and are natura…
Elementary Building Blocks for Cluster Mott Insulators
Vaishnavi Jayakumar, Ciarán Hickey
Mott insulators, in which strong Coulomb interactions fully localize electrons on single atomic sites, play host to an incredibly rich and exciting array of strongly correlated phy…
Two-dimensional coherent spectroscopy of CoNbO
Yoshito Watanabe, Simon Trebst, Ciarán Hickey +1
With recent advances in terahertz (THz) sources and detection, two-dimensional coherent spectroscopy (2DCS), which allows to probe nonlinear responses in a two-frequency plane, now…
Disentangling spin excitation continua in classical and quantum magnets using 2D nonlinear spectroscopy
Emily Z. Zhang, Ciarán Hickey, Yong Baek Kim
Inelastic neutron scattering (INS) has traditionally been one of the primary methods for investigating quantum magnets, particularly in identifying a continuum of excitations as a…
Constructing Emergent U(1) Symmetries in the Gamma-prime model
Sagar Ramchandani, Simon Trebst, Ciarán Hickey
Frustrated magnets can elude the paradigm of conventional symmetry breaking and instead exhibit signatures of emergent symmetries at low temperatures. Such symmetries arise from "a…
