Emergence of Unique Steady Edge States in Trapped Ultracold Atom Systems
Roland Cristopher F. Caballar
We show that, for a one - dimensional open quantum system of ultracold atoms trapped in an array of harmonic potentials that is weakly coupled to a background Bose - Einstein Conde…
Driven-Dissipative Dynamics of Ultracold Atoms Trapped in an Array of Harmonic Potentials
Roland Cristopher F. Caballar
We investigate the dynamics of a gas of ultracold atoms that are trapped in an array of harmonic potentials and that interacts with a Bose-Einstein condensate (BEC) that acts as a…
Dissipative Preparation of Many-Body Spin Steady States Using Trapped Ultracold Atoms
Roland Cristopher F. Caballar
This article presents a dissipative method of creating a spin steady state, or a state whose spin expectation values approaches a fixed value over time, using a trapped gas of ultr…
Quantum Propagator Dynamics of a Harmonic Oscillator in a Multimode Harmonic Oscillators Environment using White Noise Functional Analysis
Bienvenido M. Butanas, Roland Cristopher F. Caballar
White noise analysis is used to derive the propagator of an open quantum system consisting of a harmonic oscillator which is coupled to an environment consisting of N multimode har…
Dissipation induced quantum transport on a finite one-dimensional lattice
Roland Cristopher F. Caballar, Bienvenido M. Butanas, Vladimir P. Villegas +1
We construct a dissipation induced quantum transport scheme by coupling a finite lattice of two-level systems to an environment with a discrete number of energy levels. With th…
Dissipative Dynamics Of Fermion-Fermion Scattering In A Three-Site Optical Lattice
Vladimir P. Villegas, Roland Cristopher F. Caballar
In this article, we investigate the dissipative dynamics of a Fermi gas trapped in a three-site optical lattice exposed to a fermionic environment. The lattice sites admit at most…
Coupled harmonic oscillator in a multimode harmonic oscillator bath: Derivation of quantum propagator and master equation using white noise analysis
Bienvenido M. Butanas, Roland Cristopher F. Caballar
This paper presents an application of white noise functional approach to derive the quantum propagator and the evolution of the reduced density matrix for an open quantum system co…
Synchronizing quantum and classical clocks made of quantum particles
Philip Caesar M. Flores, Roland Cristopher F. Caballar, Eric A. Galapon
We demonstrate that the quantum corrections to the classical arrival time for a quantum object in a potential free region of space, as computed by Galapon [Phys. Rev. A {\bf 80}, 0…
Dissipative preparation of phase- and number-squeezed states with ultracold atoms
Roland Cristopher F. Caballar, Sebastian Diehl, Harri Mäkelä +2
We develop a dissipative quantum state preparation scheme for the creation of phase- and number-squeezed states. It utilizes ultracold atoms in a double-well configuration immersed…
Characterizing Multiple Solutions to the Time - Energy Canonical Commutation Relation via Internal Symmetries
Roland Cristopher F. Caballar, Leonard R. Ocampo, Eric A. Galapon
Internal symmetries can be used to classify multiple solutions to the time energy canonical commutation relation (TE-CCR). The dynamical behavior of solutions to the TE-CCR posessi…
Characterizing Multiple Solutions to the Time-Energy Canonical Commutation Relation via Quantum Dynamics
Roland Cristopher F. Caballar, Eric A. Galapon
We address the multiplicity of solutions to the time-energy canonical commutation relation for a given Hamiltonian. Specifically, we consider a particle spatially confined in a pot…
Confined Quantum Time of Arrival for Vanishing Potential
Eric A. Galapon, Roland F. Caballar, Ricardo Bahague
We give full account of our recent report in [E.A. Galapon, R. Caballar, R. Bahague {\it Phys. Rev. Let.} {\bf 93} 180406 (2004)] where it is shown that formulating the free quantu…
Confined Quantum Time of Arrivals
Eric A. Galapon, Roland F. Caballar, Ricardo T. Bahague
We show that formulating the quantum time of arrival problem in a segment of the real line suggests rephrasing the quantum time of arrival problem to finding states that evolve to…
