External parameters have been shown to be a powerful tool for tuning the electronic or magnetic ground state of a material. Hydrostatic pressure is a widely used external parameter but can lead to issues in the experimental procedure, such as a large background or spurious responses. Specifically, within muon spin rotation (µ+SR), a significant share of the incoming muons can stop inside the...

Frappy is a python framework to implement a device communication and abstraction layer for complex sample environment equipment such as cyostats, cryomagnets, furnaces, humidity chambers and for the integration of measurement devices. It is designed to build up complex setups for beamline experiments as well as for lab based measurements. It enables users of large scale facilities to integrate...

In this contribution we present theoretical framework for quantitative modeling of surface tension of liquids and their mixtures under high pressures. We perform molecular dynamics (MD) simulations (in GROMACS [1]) and apply statistical thermodynamics of solutions (namely Kirkwood-Buff theory) [2,3]. This allows us to describe solution structure (distribution functions) not only in coexisting...

We describe recent progress in developing a setup in which we use a diamond anvil cell (DAC) to explore phase transitions under high pressure and ultrafast photoexcitation in combination with terahertz time-domain spectroscopy (THz TDS). We aim to access pressures of up to 10 GPa at temperatures as low as 10 K.
We will present our investigation of the Mott insulator (V(1-x)Cr(x))(2)O(3)....

Following the successful guide upgrade at SINQ [1], PSI continues to improve the instrumentation to take advantage of the performance gain. The resulting boost in signal to noise enables faster data acquisition and allows more demanding experiments.
This could be experiments allowing for smaller samples sizes, at extreme conditions, with increased complexity or combinations of all...

In quantum magnets, simple degrees of freedom with short-range interactions lead to a plethora of emergent many-body phases with different exotic properties. Uniaxial pressure allows tuning these interactions selectively and engineer the underlying Hamiltonians. Hence, the properties of the emergent phases can be controlled on-demand.

Over the last years, we have developed and implemented a few different designs of uniaxial pressure devices, specifically optimized for scattering experiments.
I will present the relevant considerations for such experiments, discuss selected recent results and introduce new in-situ devices available for the user program at SINQ.
