Zero-field superconducting diode effect in small-twist-angle trilayer graphene
Jiang-Xiazi Lin, Phum Siriviboon, Harley D. Scammell +7
The critical current of a superconductor can be different for opposite directions of current flow when both time-reversal and inversion symmetry are broken. %When time-reversal and…
A new flavor of correlation and superconductivity in small twist-angle trilayer graphene
Phum Siriviboon, Jiang-Xiazi Lin, Xiaoxue Liu +8
When layers of graphene are rotationally misaligned by the magic angle, the moiré superlattice features extremely flat bands. Due to the enhanced density of states, the Coulomb int…
Crossover between Strongly-coupled and Weakly-coupled Exciton Superfluids
Xiaomeng Liu, J. I. A. Li, Kenji Watanabe +5
In fermionic systems, superconductivity and superfluidity are enabled through the condensation of fermion pairs. The nature of this condensate can be tuned by varying the pairing s…
Isospin Pomeranchuk effect and the entropy of collective excitations in twisted bilayer graphene
Yu Saito, Fangyuan Yang, Jingyuan Ge +6
In condensed matter systems, higher temperatures typically disfavors ordered phases leading to an upper critical temperature for magnetism, superconductivity, and other phenomena.…
Tuning electron correlation in magic-angle twisted bilayer graphene using Coulomb screening
Xiaoxue Liu, Zhi Wang, K. Watanabe +3
The ability to control the strength of interaction is essential for studying quantum phenomena emerging from a system of correlated fermions. For example, the isotope effect illust…
Dissipation-enabled hydrodynamic conductivity in a tunable bandgap semiconductor
Cheng Tan, Derek Y. H. Ho, Lei Wang +10
Electronic transport in the regime where carrier-carrier collisions are the dominant scattering mechanism has taken on new relevance with the advent of ultraclean two-dimensional m…
Evidence for pairing states of composite fermions in double-layer graphene
J. I. A. Li, Q. Shi, Y. Zeng +4
Pairing interaction between fermionic particles leads to composite Bosons that condense at low temperature. Such condensate gives rise to long range order and phase coherence in su…
Excitonic superfluid phase in Double Bilayer Graphene
J. I. A. Li, T. Taniguchi, K. Watanabe +2
Spatially indirect excitons can be created when an electron and a hole, confined to separate layers of a double quantum well system, bind to form a composite Boson. Because there i…
Direct measurement of discrete valley and orbital quantum numbers in a multicomponent quantum Hall system
B. M. Hunt, J. I. A. Li, A. A. Zibrov +8
Strongly interacting two dimensional electron systems (2DESs) host a complex landscape of broken symmetry states. The possible ground states are further expanded by internal degree…
Negative Coulomb Drag in Double Bilayer Graphene
J. I. A. Li, T. Taniguchi, K. Watanabe +3
Coulomb drag between parallel quantum wells provides a uniquely sensitive measurement of electron correlations since the drag response depends on interactions only. Recently it has…
The Superfluid Glass Phase of 3He-A
J. I. A. Li, J. Pollanen, A. M. Zimmerman +3
It is established theoretically that an ordered state with continuous symmetry is inherently unstable to arbitrarily small amounts of disorder [1, 2]. This principle is of central…
Zeeman splitting and nonlinear field-dependence in superfluid 3He
C. A. Collett, J. Pollanen, J. I. A. Li +2
We have studied the acoustic Faraday effect in superfluid 3He up to significantly larger magnetic fields than in previous experiments achieving rotations of the polarization of tra…
Nonlinear field-dependence and f-wave interactions in superfluid 3He
C. A. Collett, J. Pollanen, J. I. A. Li +2
We present results of transverse acoustics studies in superfluid ^{3}He-B at fields up to 0.11 T. Using acoustic cavity interferometry, we observe the Acoustic Faraday Effect for a…
New Chiral Phases of Superfluid 3He Stabilized by Anisotropic Silica Aerogel
J. Pollanen, J. I. A. Li, C. A. Collett +3
A rich variety of Fermi systems condense by forming bound pairs, including high temperature [1] and heavy fermion [2] superconductors, Sr2RuO4 [3], cold atomic gases [4], and super…
