Atomistic tight-binding Hartree-Fock calculations of multielectron configurations in P-doped silicon devices: wavefunction reshaping
Maicol A. Ochoa, Keyi Liu, Piotr Różański +2
Donor-based quantum devices in silicon are attractive platforms for universal quantum computing and analog quantum simulations. The nearly-atomic precision in dopant placement prom…
A semiclassical nonequilibrium Green's Function approach to electron transport in systems exhibiting electron-phonon couplings
Maicol A. Ochoa
We formulate a semiclassical theory for electron transport in open quantum systems with electron-phonon interactions adequate for situations when the system's phonon dynamics is co…
Single-electron states of phosphorus-atom arrays in silicon
Maicol A. Ochoa, Keyi Liu, Michał Zieliński +1
We characterize the single-electron energies and the wavefunction structure of arrays with two, three, and four phosphorus atoms in silicon by implementing atomistic tight-binding…
Lossy anharmonic polaritons under periodic driving
Maicol A. Ochoa
We report on the anharmonic signatures in dissipative polaritons' stationary energy distribution and thermodynamics under external periodic driving. First, we introduce a dynamic m…
Quantum thermodynamics of periodically driven polaritonic systems

We investigate the energy distribution and quantum thermodynamics in periodically driven polaritonic systems in the stationary state at room temperature. Specifically, we consider…
Coupling, lifetimes and "strong coupling" maps for single molecules at plasmonic interfaces
Monosij Mondal, Maicol A. Ochoa, Maxim Sukharev +1
The interaction between excited states of a molecule and excited states of metal nanostructure (e.g. plasmons) leads to hybrid states with modified optical properties. When plasmon…

Christoph Rohmann, Maicol A. Ochoa, Michael Zwolak
The adsorption of metal atoms on nanostructures, such as graphene and nanotubes, plays an important role in catalysis, electronic doping, and tuning material properties. Quantum ch…

Maicol A. Ochoa, Michael Zwolak
We investigate protocols for optimal molecular detection with electromechanical nanoscale sensors in ambient conditions. Our models are representative of suspended graphene nanorib…
Generalized Voigt broadening due to thermal fluctuations of electromechanical nanosensors and molecular electronic junctions
Maicol A. Ochoa, Michael Zwolak
Graphene and other 2D materials give a platform for electromechanical sensing of biomolecules in aqueous, room temperature environments. The electronic current changes in response…

Maicol A. Ochoa, Natalya Zymbovskaya, Abraham Nitzan
We investigate two prototypical dissipative bosonic systems under slow driving and arbitrary system-bath coupling strength, recovering their dynamic evolution as well as the heat a…
Simultaneous weak measurement of non-commuting observables
Maicol A. Ochoa, Wolfgang Belzig, Abraham Nitzan
In contrast to a projective quantum measurement in which the system is projected onto an eigenstate of the measured operator, in a weak measurement the system is only weakly pertur…
Quantum mechanics in a metric sheaf: a model theoretic approach
