Many-Body Bound States in the Continuum
Shoki Sugimoto, Yuto Ashida, Masahito Ueda
A bound state in the continuum (BIC) is a spatially bounded energy eigenstate lying in a continuous spectrum of extended eigenstates. While various types of single-particle BICs ha…
Cavity-enhanced Kondo effect
Jun Mochida, Yuto Ashida
In metals containing magnetic impurities, conduction electrons screen the magnetic impurities and induce the Kondo effect, i.e., the enhancement of the electrical resistance at low…
Cavity Moiré Materials: Controlling Magnetic Frustration with Quantum Light-Matter Interaction
Kanta Masuki, Yuto Ashida
Cavity quantum electrodynamics (QED) studies the interaction between light and matter at the single quantum level and has played a central role in quantum science and technology. C…
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…
Mixed-state phase transitions in spin-Holstein models
Brett Min, Yuxuan Zhang, Yuxuan Guo +2
Understanding coupled electron-phonon systems is one of the fundamental issues in strongly correlated systems. In this work, we aim to extend the notion of mixed-state phases to th…
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…
