P NMR study of discrete time-crystalline signatures in an ordered crystal of ammonium dihydrogen phosphate

Jared Rovny, Robert L. Blum, Sean E. Barrett

The rich dynamics and phase structure of driven systems includes the recently described phenomenon of the "discrete time crystal" (DTC), a robust phase which spontaneously breaks t…

Observation of Discrete-Time-Crystal Signatures in an Ordered Dipolar Many-Body System

Jared Rovny, Robert L. Blum, Sean E. Barrett

A discrete time crystal (DTC) is a robust phase of driven systems that breaks the discrete time translation symmetry of the driving Hamiltonian. Recent experiments have observed DT…

Controlling coherence using the internal structure of hard pi pulses

Yanqun Dong, R. G. Ramos, Dale Li +1

The tiny difference between hard pi pulses and their delta-function approximation can be exploited to control coherence. Variants on the magic echo that work despite a large spread…

Generating Unexpected Spin Echoes in Dipolar Solids with Pi Pulses

Dale Li, A. E. Dementyev, Yanqun Dong +2

NMR spin echo measurements of C-13 in C60, Y-89 in Y2O3, and Si-29 in silicon are shown to defy conventional expectations when more that one pi pulse is used. Multiple pi-pulse ech…

The Intrinsic Origin of Spin Echoes in Dipolar Solids Generated by Strong Pi Pulses

Dale Li, Yanqun Dong, R. G. Ramos +4

In spectroscopy, it is conventional to treat pulses much stronger than the linewidth as delta-functions. In NMR, this assumption leads to the prediction that pi pulses do not refoc…
