Bosonic lasing and trapping of a dressed photon fluid in InGaN at room temperature

Munise Nevin Cobet

The generation of a quantum fluid of dressed photons at room temperature is experimentally demonstrated in an InGaN microcavity which is divided into two-and one-dimensional sections, resulting in single- and switchable multilevel coherent light emission. ...

Thermal transport in low dimensions

Andrea Cepellotti

Lattice vibrations are the microscopic mechanism responsible for a large, if not dominant, contribution to heat transport in crystalline insulators. These vibrations are described in terms of phonons, collective excitations (or quasiparticles) in the form ...

Inner-shell magnetic dipole transition in Tm atoms: A candidate for optical lattice clocks

Sergey Fedorov

We consider a narrow magneto-dipole transition in the Tm-169 atom at the wavelength of 1.14 mu m as a candidate for a two-dimensional-optical lattice clock. Calculating dynamic polarizabilities of the two clock levels [Xe]4f(13)6s(2)(J = 7/2) and [Xe]4f(13 ...

Scanning thermal probe microscope method for the determination of thermal diffusivity of nanocomposite thin films

Jürgen Brugger, Khushboo Agarwal

A commercial scanning thermal microscope has been upgraded to facilitate its use in estimating the radial thermal diffusivity of thin films close to room temperature. The modified setup includes a microcontroller driven microhotplate coupled with a Bluetoo ...

A new strain rate dependent continuum framework for Mg alloys

Magnesium (Mg) alloys have recently been put under the spotlight for their specific strength, the highest among structural metals. Although the mechanical behaviour of Mg alloys at quasi-static strain rates has been extensively modelled in the recent years ...

MilliKelvin resolution in cryogenic temperature distributed fibre sensing based on coherent Rayleigh scattering

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Xin Lu

The response of a distributed temperature sensor based on coherent Rayleigh scattering is experimentally studied in the temperature range from 77 K up to 300 K, using fibres with standard and ORMOCER coating. A precise and absolute frequency scan is perfor ...

Thermal Conductivity of Monolayer Molybdenum Disulfide Obtained from Temperature-Dependent Raman Spectroscopy

Andras Kis, Simone Bertolazzi, Jacopo Brivio

Atomically thin molybdenum disulfide (MoS2) offers potential for advanced devices and an alternative to graphene due to its unique electronic and optical properties. The temperature-dependent Raman spectra of exfoliated, monolayer MoS2 in the range of 100- ...

Impact of Cable Twist Pitch on T-cs-Degradation and AC Loss in Nb3Sn Conductors for ITER Central Solenoids

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov

The performance of tour Nb3Sn conductors for the ITER central solenoids was tested. The current sharing temperatures (T-cs) were measured over approximately 9000 electromagnetic cycles, including two or three thermal cycles between 4.2 K and room temperatu ...
