Current-induced spin torque resonance of a magnetic insulator
Michael Schreier, Takahiro Chiba, Arthur Niedermayr +7
Pure spin currents transport angular momentum without an associated charge flow. This unique property makes them attractive for spintronics applications, such as torque induced mag…
Ultrastrong coupling in two-resonator circuit QED
A. Baust, E. Hoffmann, M. Haeberlein +17
We report on ultrastrong coupling between a superconducting flux qubit and a resonant mode of a system comprised of two superconducting coplanar stripline resonators coupled galvan…
Exchange Magnon-Polaritons in Microwave Cavities
Yunshan Cao, Peng Yan, Hans Huebl +2
We formulate a scattering theory to study magnetic films in microwave cavities beyond the independent-spin and rotating wave approximations of the Tavis-Cummings model. We demonstr…
Fourier synthesis of radio frequency nanomechanical pulses with different shapes
Florian J. R. Schülein, Eugenio Zallo, Paola Atkinson +5
The concept of Fourier synthesis is heavily employed in both consumer electronic products and fundamental research. In the latter, pulse shaping is key to dynamically initialize, p…
Longitudinal spin Seebeck effect contribution in transverse spin Seebeck effect experiments in Pt/YIG and Pt/NFO
Daniel Meier, Daniel Reinhardt, Michael van Straaten +10
We investigate the inverse spin Hall voltage of a 10nm thin Pt strip deposited on the magnetic insulators Y3Fe5O12 (YIG) and NiFe2O4 (NFO) with a temperature gradient in the film p…
Confocal shift interferometry of coherent emission from trapped dipolar excitons
Jens Repp, Georg J. Schinner, Enrico Schubert +6
We introduce a confocal shift-interferometer based on optical fibers. The presented spectroscopy allows measuring coherence maps of luminescent samples with a high spatial resoluti…
Dynamic Acoustic Control of Individual Optically Active Quantum Dot-like Emission Centers in Heterostructure Nanowires
Matthias Weiß, Jörg B. Kinzel, Florian J. R. Schülein +10
We probe and control the optical properties of emission centers forming in radial het- erostructure GaAs-Al0.3Ga0.7As nanowires and show that these emitters, located in Al0.3Ga0.7A…
Thermoelectric transport through a quantum nanoelectromechanical system and its backaction
Hangbo Zhou, Juzar Thingna, Jian-Sheng Wang +1
We present a comprehensive study of thermoelectric transport properties of a quantum nanoelectromechanical system (NEMS) described by a single-electron-transistor (SET) coupled to…
Independent dynamic acousto-mechanical and electrostatic control of individual quantum dots in a LiNbO-GaAs hybrid
J. Pustiowski, K. Müller, M. Bichler +4
We demonstrate tuning of single quantum dot emission lines by the combined action of the dynamic acoustic field of a radio frequency surface acoustic wave and a static electric fie…
Spin Hall noise
Akashdeep Kamra, Friedrich P. Witek, Sibylle Meyer +5
We measure the low-frequency thermal fluctuations of pure spin current in a Platinum film deposited on yttrium iron garnet via the inverse spin Hall effect (ISHE)-mediated voltage…
Brownian motors in micro-scale domain: Enhancement of efficiency by noise
Jakub Spiechowicz, Peter Hänggi, Jerzy Łuczka
We study a noisy drive mechanism for efficiency enhancement of Brownian motors operating on the micro-scale domain. It was proven [J. Spiechowicz et al., J. Stat. Mech. P02044, (20…
Josephson junction ratchet: effects of finite capacitances
Jakub Spiechowicz, Peter Hänggi, Jerzy Łuczka
We study transport in an asymmetric SQUID which is composed of a loop with three capacitively and resistively shunted Josephson junctions: two in series in one arm and the remainin…
On-chip generation, routing and detection of quantum light
Günther Reithmaier, Michael Kaniber, Fabian Flassig +6
Semiconductor based photonic information technologies are rapidly being pushed to the quantum limit where non-classical states of light can be generated, manipulated and exploited…

Using integrated superconducting single photon detectors we probe ultra-slow exciton capture and relaxation dynamics in single self-assembled InGaAs quantum dots embedded in a GaAs…
Ultrafast electronic read-out of diamond NV centers coupled to graphene
Andreas Brenneis, Louis Gaudreau, Max Seifert +6
Nonradiative transfer processes are often regarded as loss channels for an optical emitter1, since they are inherently difficult to be experimentally accessed. Recently, it has bee…
Improved Dyson series expansion for steady-state quantum transport beyond the weak coupling limit - divergences and resolution
Juzar Thingna, Hangbo Zhou, Jian-Sheng Wang
We present a general theory to calculate the steady-state heat and electronic currents for nonlinear systems using a perturbative expansion in the system-bath coupling. We explicit…
Thermodynamic laws in isolated systems
Stefan Hilbert, Peter Hänggi, Jörn Dunkel
The recent experimental realization of exotic matter states in isolated quantum systems and the ensuing controversy about the existence of negative absolute temperatures demand a c…
Infinite densities for Lévy walks
Adi Rebenshtok, Sergey Denisov, Peter Hanggi +1
Motion of particles in many systems exhibits a mixture between periods of random diffusive like events and ballistic like motion. In many cases, such systems exhibit strong anomalo…
Determination of effective mechanical properties of a double-layer beam by means of a nano-electromechanical transducer
Fredrik Hocke, Matthias Pernpeintner, Xiaoqing Zhou +4
We investigate the mechanical properties of a doubly-clamped, double-layer nanobeam embedded into an electromechanical system. The nanobeam consists of a highly pre-stressed silico…
