Optically Driven Formation of Tailored Phonon Cavities
Advanced Science, EarlyView.It is demonstrated that a structured optical field creates nanoscale “phonon cavities” in van der Waals materials, where atomic vibrations are confined and controlled in space and time. This approach enables programmable control of cavity geometry, symmetry, and frequency, and provides a platform for ultrafast studies of nonequilibrium interactions and

Multipartite Entanglement Generation in a Structured Environment
Entropy, 2020 In this paper, we investigate the entanglement generation of n-qubit states in a model consisting of n independent qubits, each coupled to a harmonic oscillator which is in turn coupled to a bath of N additional harmonic oscillators with nearest-neighbor

Quantum harmonic oscillators and thermalization
, 2021 We study a quantum harmonic oscillator undergoing thermalization. To describe the thermalization process, we generalize the Ermakov-Lewis-Riesenfeld (ELR) invariant method for the oscillator. After imposing appropriate conditions on the thermalization process, we introduce an ansatz equation that describes the time evolution effectively.

Ultrasensitive Diamond Cantilever‐Based Optical Microphone
Advanced Science, EarlyView.The first demonstration that high quality diamond cantilevers function as high‐sensitivity acoustic transducers is reported, combining CVD diamond cantilevers and an extrinsic Fabry‐Perot optical configuration. High transduction efficiency yields record sensitivity (51.5 VPa−1) and MDP (0.018 µPa/Hz$\rm {\sqrt {Hz}}$), enabling durable, low‐noise ...

On The Harmonic Oscillator Group [PDF]
, 2011 We discuss the maximum kinematical invariance group of the quantum harmonic oscillator from a view point of the Ermakov-type system. A six parameter family of the square integrable oscillator wave functions, which seems cannot be obtained by the standard

Amplitude and phase representation of quantum invariants for the time dependent harmonic oscillator
, 2002 The correspondence between classical and quantum invariants is established. The Ermakov Lewis quantum invariant of the time dependent harmonic oscillator is translated from the coordinate and momentum operators into amplitude and phase operators.

Crossing the Oxo‐Peroxo Wall for Selective Electrochemical Epoxidation
Advanced Science, EarlyView.The classical Oxo‐Wall concept is extended to an Oxo–Peroxo Wall framework, showing that meta‐stable oxo species favor peroxo and superoxo formation, decoupling from oxygen evolution reaction (OER). This new understanding enables selective C‐C bond oxidations and provides a predictive alternative oxidation reaction (AOR) volcano for designing metal ...

Deterministic nonlinear phase gates induced by a single qubit
New Journal of Physics, 2018 We propose deterministic realizations of nonlinear phase gates by repeating a finite sequence of non-commuting Rabi interactions between a harmonic oscillator and only a single two-level ancillary qubit.
