Thermodynamics of a physical model implementing a Maxwell demon
Philipp Strasberg, Gernot Schaller, Tobias Brandes +1
We present a physical implementation of a Maxwell demon which consists of a conventional single electron transistor (SET) capacitively coupled to another quantum dot detecting its…
Phonon Laser Effect and Dicke-Hepp-Lieb Superradiant Phase Transition in Magnetic Cantilever Coupled to a Bose Einstein Condensate
Aranya B. Bhattacherjee, Tobias Brandes
We propose a possibility of a phonon laser by coupling a Bose-Einstein condensate to a nanomechanical cantilever with a magnetic tip. Due to the magnetic coupling, atomic spin flip…
Superradiant phase transition in a model of three-level-lambda systems interacting with two bosonic modes
Mathias Hayn, Clive Emary, Tobias Brandes
We consider an ensemble of three-level particles in lambda-configuration interacting with two bosonic modes. The Hamiltonian has the form of a generalized Dicke-model. We show that…
Reverse quantum state engineering using electronic feedback loops
Gerold Kiesslich, Clive Emary, Gernot Schaller +1
We propose an all-electronic technique to manipulate and control interacting quantum systems by unitary single-jump feedback conditioned on the outcome of a capacitively coupled el…
Spin entangled two-particle dark state in quantum transport through coupled quantum dots
Christina Pöltl, Clive Emary, Tobias Brandes
We present a transport setup of coupled quantum dots that enables the creation of spatially separated spin-entangled two-electron dark states. We prove the existence of an entangle…
Criticality in transport through the quantum Ising chain
Malte Vogl, Gernot Schaller, Tobias Brandes
We consider thermal transport between two reservoirs coupled by a quantum Ising chain as a model for non-equilibrium physics induced in quantum-critical many-body systems. By deriv…
