Preparation of conditionally squeezed states in qubit-oscillator systems

Physical Review Research
Inspired by recent advances in the manipulation of superconducting circuits coupled to mechanical modes in the quantum regime, we propose a protocol for generating superpositions of orthogonally squeezed states in a quantum harmonic oscillator.

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.

Deformed Heisenberg algebras, a Fock-space representation and the Calogero model

, 2000
We describe generally deformed Heisenberg algebras in one dimension. The condition for a generalized Leibniz rule is obtained and solved. We analyze conditions under which deformed quantum-mechanical problems have a Fock-space representation.

Non‐Uniform Space‐Time‐Coding Modulation for Low‐Complexity Diagnostics of Reconfigurable Intelligent Surfaces

Advanced Electronic Materials, EarlyView.
A diagnostic method for reconfigurable intelligent surfaces (RIS) based on non‐uniform space‐time‐coding modulation is presented. Fault localization is achieved via amplitude‐only spectral measurements, eliminating the need for complex signal processing. A one‐to‐one mapping between harmonic components and RIS elements enables accurate detection.

Cooper pairing and single particle properties of trapped Fermi gases

, 2002
We calculate the elementary excitations and pairing of a trapped atomic Fermi gas in the superfluid phase. The level spectra and pairing gaps undergo several transitions as the strength of the interactions between and the number of atoms are varied.

Electrically Tunable Room‐Temperature Microwave Oscillations in GaN/AlN Triple‐Barrier Resonant Tunneling Diodes

Advanced Electronic Materials, EarlyView.
III‐nitride semiconductors have revolutionized optoelectronics, enabling transformative technologies such as high‐efficiency LEDs and lasers. However, their use in intersubband optoelectronics has remained limited. This work marks an important step forward by demonstrating highly coherent inter‐well resonant tunneling injection in III‐nitride ...

Harmonic analysis of oscillators through standard numerical continuation tools

, 2010
In this paper, we describe a numerical continuation method that enables harmonic analysis of nonlinear periodic oscillators. This method is formulated as a boundary value problem that can be readily implemented by resorting to a standard continuation ...
