Modeling and Understanding Neural Weights of Humanoid Policies with Diffusion
Huixuan Cheng, Bike Zhang, Shankar Sastry +1
Recent advances in robot learning have driven rapid progress in humanoid control, enabling increasingly agile behaviors in the real world. However, humanoid control networks are ty…
Direct Evidence of Unconventional Superconductivity in Doped Kagome system RVSb
Avior Almoalem, Yuqing Xing, Iksu Jang +7
The superconducting pairing symmetry of kagome metals remains a central unresolved question largely because phase-sensitive experiments capable of distinguishing between different…
Unbiased large- approach to competing vestigial orders of density-wave and superconducting instabilities
Grgur Palle, Rafael M. Fernandes
When a primary order breaks multiple symmetries, partially ordered phases that only break a subset of those symmetries, known as vestigial phases, may onset at a higher temperature…
Hopf symmetry protected topological phases in the vicinity of spin orders
Grgur Palle
Hopf terms are topological theta terms that are associated with a host of interesting physics, including anyons, statistical transmutation, chiral edge states, and the spin quantum…
Superconductivity in kagome metals due to soft loop-current fluctuations
Daniel J. Schultz, Grgur Palle, Asimpunya Mitra +3
We demonstrate that soft fluctuations of translation symmetry-breaking loop currents provide a mechanism for unconventional superconductivity in kagome metals that naturally addres…
Elastic Quantum Criticality in Nematics and Altermagnets via the Elasto-Caloric Effect
Charles R. W. Steward, Grgur Palle, Markus Garst +2
The coupling between electronic nematic degrees of freedom and acoustic phonons is known to significantly alter the universality class of a nematic quantum critical point (QCP). Wh…
Unconventional Superconductivity in Correlated, Multiband, and Topological Systems
Grgur Palle
In this thesis, we theoretically examine the pairing mechanisms and the identification of the pairing symmetry of unconventional superconductors whose normal states are correlated,…
Unconventional superconductivity from electronic dipole fluctuations
Grgur Palle, Jörg Schmalian
We study electron-electron Coulomb interactions in electronic systems whose Fermi surfaces possess a finite electric dipole density. Although there is no net dipole moment, we show…
and the elastocaloric effect of SrRuO under uniaxial stress: no indications of transition splitting
Fabian Jerzembeck, You-Sheng Li, Grgur Palle +11
There is considerable evidence that the superconductivity of Sr2RuO4 has two components. Among this evidence is a jump in the shear elastic modulus at the critical tempera…
Comment on "Towards exact solutions for the superconducting induced by electron-phonon interaction"
Grgur Palle
In a series of recent articles, Liu, Yang, Pan, et al. claim to have determined the exact dressed electron-boson vertex for a number of very general interacting many-body problems…
Superconductivity due to fluctuating loop currents
Grgur Palle, Risto Ojajärvi, Rafael M. Fernandes +1
Orbital magnetism and the loop currents (LC) that accompany it have been proposed to emerge in many systems, including cuprates, iridates, and kagome superconductors. In the case o…
Constraints on the superconducting state of SrRuO from elastocaloric measurements
Grgur Palle, Clifford Hicks, Roser Valentí +6
Strontium ruthenate SrRuO is an unconventional superconductor whose pairing symmetry has not been fully clarified, despite more than two decades of intensive research. Rece…
Physical limitations of the Hohenberg-Mermin-Wagner theorem
Grgur Palle, D. K. Sunko
The Hohenberg-Mermin-Wagner (HMW) theorem states that infrared (IR) fluctuations prevent long-range order which breaks continuous symmetries in two dimensions (2D), at finite tempe…
Fracton-elasticity duality in twisted moiré superlattices
Jonas Gaa, Grgur Palle, Rafael M. Fernandes +1
We formulate a fracton-elasticity duality for twisted moiré superlattices, taking into account that they are incommensurate crystals with dissipative phason dynamics. From a dual t…
Exactly solvable spin-1/2 XYZ models with highly-degenerate, partially ordered, ground states
Grgur Palle, Owen Benton
Exactly solvable models play a special role in Condensed Matter physics, serving as secure theoretical starting points for investigation of new phenomena. Changlani et al. [Phys. R…
