Cavity Quantum Electrodynamics at Arbitrary Light-Matter Coupling Strengths
Yuto Ashida, Atac Imamoglu, Eugene Demler
Quantum light-matter systems at strong coupling are notoriously challenging to analyze due to the need to include states with many excitations in every coupled mode. We propose a n…
Rectification in Nonequilibrium Steady States of Open Many-Body Systems
Kazuki Yamamoto, Yuto Ashida, Norio Kawakami
We study how translationally invariant couplings of many-particle systems and nonequilibrium baths can be used to rectify particle currents, for which we consider minimal setups to…
Measurement-induced quantum criticality under continuous monitoring
Yohei Fuji, Yuto Ashida
We investigate entanglement phase transitions from volume-law to area-law entanglement in a quantum many-body state under continuous position measurement on the basis of the quantu…
PT-symmetric non-Hermitian quantum many-body system using ultracold atoms in an optical lattice with controlled dissipation
Yosuke Takasu, Tomoya Yagami, Yuto Ashida +3
We report our realization of a parity-time (PT) symmetric non-Hermitian many-body system using cold atoms with dissipation. After developing a theoretical framework on PT-symmetric…
Quantum Electrodynamic Control of Matter: Cavity-Enhanced Ferroelectric Phase Transition
Yuto Ashida, Atac Imamoglu, Jerome Faist +3
The light-matter interaction can be utilized to qualitatively alter physical properties of materials. Recent theoretical and experimental studies have explored this possibility of…
Probing XY phase transitions in a Josephson junction array with tunable frustration
R. Cosmic, K. Kawabata, Y. Ashida +5
The seminal theoretical works of Berezinskii, Kosterlitz, and Thouless presented a new paradigm for phase transitions in condensed matter that are driven by topological excitations…
