Lanthanides, like erbium and dysprosium, have emerged as powerful platforms for quantum-gas research due to their diverse properties, including a significant large spin manifold in their absolute ground state. However, effectively exploiting the spin

Usually, increasing the temperature of a system leads to disorder but supersolids can show the opposite trend. Here, the authors discuss the observation of a supersolid phase in a dilute gas of dysprosium atoms by increasing their temperature.

We investigate the excitation spectrum and compressibility of a dipolar Bose-Einstein condensate in an infinite tube potential in the parameter regime where the transition between superfluid and supersolid phases occurs. Our study focuses on the dens

We report on the observation and coherent excitation of atoms on the narrow inner-shell orbital transition, connecting the erbium ground state [Xe]4f^{12}(^{3}H_{6})6s^{2} to the excited state [Xe]4f^{11}((^{4}I_{15/2})^{0})5d(^{5}D_{3/2})6s^{2}(15/2

We present a study of the Rydberg spectrum in ^{166}Er for series connected to the 4f^{12}(^{3}H_{6})6s, J_{c}=13/2, and J_{c}=11/2 ionic core states using an all-optical detection based on electromagnetically induced transparency in an effusive atom

We present a theory for the emergence of a supersolid state in a cigar-shaped dipolar quantum Bose gas. Our approach is based on a reduced three-dimensional (3D) theory, where the condensate wave function is decomposed into an axial field and a trans

Dipolar interactions are ubiquitous in nature and rule the behavior of a broad range of systems spanning from energy transfer in biological systems to quantum magnetism. Here we study magnetization-conserving dipolar induced spin-exchange dynamics in

In a joint experimental and theoretical effort, we report on the formation of a macrodroplet state in an ultracold bosonic gas of erbium atoms with strong dipolar interactions. By precise tuning of the s-wave scattering length below the so-called dip

We show that for ultracold magnetic lanthanide atoms chaotic scattering emerges due to a combination of anisotropic interaction potentials and Zeeman coupling under an external magnetic field. This scattering is studied in a collaborative experimenta
