Explore the cutting-edge research on dissipative quantum phase transitions and cavity quantum electrodynamics (QED) in this 33-minute conference talk. Delve into the world of strong coupling between matter and quantized electromagnetic modes, and discover how this interaction can be used to control equilibrium phases and dynamics of quantum many-body systems. Learn about recent developments in achieving strong light-matter interaction in nonperturbative regimes, and understand the challenges faced by conventional theoretical methods in analyzing these systems. Gain insights into an innovative approach using asymptotically disentangling unitary transformation to analyze strongly coupled quantum light-matter systems at arbitrary interaction strengths. Examine applications of this method in constructing tight-binding Hamiltonians, studying the dynamics of bound states in the continuum, and revisiting dissipative quantum phase transitions in resistively shunted Josephson junctions. Follow the speaker's journey through various aspects of the research, including cavity QED, experimental setups, couplings, unitary transmission, and energy analysis, culminating in a comprehensive summary of dissipative transitions in quantum systems.
