We show that locally interacting, periodically driven (Floquet) Hamiltonian dynamics coupled
to a Langevin bath support finite-temperature discrete time crystals (DTCs) with an infinite …

Symmetry-protected topological order in one dimension leads to protected degeneracies
between symmetry blocks of the reduced density matrix. In the presence of periodic driving …

We consider a dissipative quantum Ising model periodically driven by a train of π pulses and
investigate dissipative discrete time crystals (DTCs) in solids. In this model, the interaction …

Many-body phenomena far from equilibrium present challenges beyond reach by classical
computational resources. Digital quantum computers provide a possible way forward but …

We propose a general protocol for engineering dissipative time crystals in quantum open
systems through symmetry-induced fragmentation and ergodicity breaking. Building upon a …

Understanding condensed matter systems involves understanding the interactions of many-
body systems and studying the emerging phases and phase transitions of these quantum …

This dissertation focuses on using light to achieve ultrafast control of quantum materials,
particularly through the nonlinear phononics mechanism. This allows for dynamical control …
