Unveiling new quantum phases in the Shastry-Sutherland compound SrCu2(BO3)(2) up to the saturation magnetic field
Under magnetic fields, quantum magnets often undergo exotic phase transitions with various kinds of order. The discovery of a sequence of fractional magnetization plateaus in the Shastry-Sutherland compound SrCu2(BO3)(2) has played a central role in the hi ...
NATURE PORTFOLIO2023Confirming the high pressure phase diagram of the Shastry-Sutherland model
Henrik Moodysson Rønnow, Martin Mansson
A Muon Spin Rotation (mu+SR) study was conducted to investigate the magnetic properties of SrCu2(BO3)(2) (SCBO) as a function of temperature/pressure. Measurements in zero field and transverse field confirm the absence of long range magnetic order at high ...
IOP PUBLISHING LTD2023Many-body physics with strongly interacting fermions coupled to light
This thesis reports on the realization of the first experiments conducted with superfluid, strongly interacting Fermi gases of 6Li coupled to the light field of an optical cavity. In the scope of existing ultracold atomic platforms, this is the first time ...
EPFL2023Correlated insulator collapse due to quantum avalanche via in-gap ladder states
Camille Didier Georges Aron, Xi Chen
The significant discrepancy observed between the predicted and experimental switching fields in correlated insulators under a DC electric field far-from-equilibrium necessitates a reevaluation of current microscopic understanding. Here we show that an elec ...
NATURE PORTFOLIO2023Magnon-phonon interactions enhance the gap at the Dirac point in the spin-wave spectra of CrI3 two-dimensional magnets
Recent neutron-diffraction experiments in honeycomb CrI3 quasi-2D ferromagnets have evinced the existence of a gap at the Dirac point in their spin-wave spectra. The existence of this gap has been attributed to strong in-plane Dzyaloshinskii-Moriya or Kita ...
AMER PHYSICAL SOC2023Numerical investigation of bound states in quantum magnets
Bound-states of particles are an interesting problem in quantum mechanics dating back to 1931 Bethe's solution of spin-1/2 Heisenberg chain. These exotic composite states are realized in quantum magnets and are detectable in inelastic neutron scattering (I ...
EPFL2023Momentum-resolved spin-conserving two-triplon bound state and continuum in a cuprate ladder
Henrik Moodysson Rønnow, Thorsten Schmitt, Vladimir N. Strocov, Yi Tseng
Studying multi-particle elementary excitations has provided unique access to understand collective many-body phenomena in correlated electronic materials, paving the way towards constructing microscopic models. In this work, we perform O K-edge resonant in ...
NATURE PORTFOLIO2023Unbiasing time-dependent Variational Monte Carlo by projected quantum evolution
Giuseppe Carleo, Clemens Giuliani, Alessandro Sinibaldi, Filippo Vicentini
We analyze the accuracy and sample complexity of variational Monte Carlo approaches to simulate the dynamics of many-body quantum systems classically. By systematically studying the relevant stochastic estimators, we are able to: (i) prove that the most us ...
