Fractons emerge from many-body systems, featuring subdimensional particles with
restricted mobility. These particles have attracted interest for their roles across disciplines …

Magnons are quantized collective spin-wave excitations in magnetically ordered materials.
Revealing the interactions among these collective modes is crucial for the understanding of …

The burgeoning field of “fractons,” a class of models where quasiparticles are strictly
immobile or display restricted mobility that can be understood through generalized …

We explore universality and phases of matter in hybrid quantum dynamics combining
chaotic time evolution and projective measurements. We develop a unitary representation of …

Two-dimensional coherent spectroscopy (2DCS) is a nonlinear spectroscopy technique
capable of identifying whether apparent continua in linear response are made out of …

The identification of microscopic systems describing the low-energy properties of correlated
materials has been a central goal of spectroscopic measurements. We demonstrate how two …

We develop a formalism for computing the nonlinear response of interacting integrable
systems. Our results are asymptotically exact in the hydrodynamic limit where perturbing …

Two-dimensional coherent terahertz spectroscopy (2DCS) emerges as a valuable tool to
probe the nature, couplings, and lifetimes of excitations in quantum materials. It thus …

We study the nonlinear response of nonintegrable one-dimensional (1D) spin models using
infinite matrix-product state techniques. As a benchmark and demonstration of the method …

We study theoretically the nonlinear optical response of Tomonaga-Luttinger spin liquid in
the context of terahertz (THz) two-dimensional coherent spectroscopy (2DCS). Using the …
