Correspondence Between the Energy Equipartition Theorem in Classical Mechanics and its Phase-Space Formulation in Quantum Mechanics
Esteban Marulanda, Alejandro Restrepo, Johans Restrepo
In classical physics there is a well-known theorem in which it is established that the energy per degree of freedom is the same. However, in quantum mechanics due to the non-commut…
Topological circuit of a versatile non-Hermitian quantum system
David-Andres Galeano, Xiao-Xiao Zhang, Jorge Mahecha
We propose an resistors, inductors and capacitors (RLC) electrical circuit to theoretically analyze and fully simulate a new type of non-Hermitian Su-Schrieffer-Heeger (SSH) model…
Discriminating Quantum States with Quantum Machine Learning
David Quiroga, Prasanna Date, Raphael C. Pooser
Quantum machine learning (QML) algorithms have obtained great relevance in the machine learning (ML) field due to the promise of quantum speedups when performing basic linear algeb…
Quantum Phase Transition and Berry Phase in an Extended Dicke Model
C. A. Estrada Guerra, J. Mahecha-Gómez, J. G. Hirsch
We investigate quantum phase transitions, quantum criticality, and Berry phase for the ground state of an ensemble of non-interacting two-level atoms embedded in a non-linear optic…
Equilibrium Coherence in the Multi-level Spin-boson Model
Mike Reppert, Deborah Reppert, Leonardo A. Pachon +1
Interaction between a quantum system and its environment can induce stationary coherences -- off-diagonal elements in the reduced system density matrix -- even at equilibrium. This…
Thermal transistor effect in quantum systems
Antonio Mandarino, Karl Joulain, Melisa Domínguez Gómez +1
We study a quantum system composed of three interacting qubits, each coupled to a different thermal reservoir. We show how to engineer it in order to build a quantum device that is…
