Van Hove singularity-driven giant Nernst signal in twisted double bilayer graphene
Ujjal Roy, Monosij Roy, Unmesh Ghorai +8
Twisted graphene layers host van Hove singularities (vHSs), peaks in the electronic density of states, thought to drive exotic phases in moiré materials, but their effect on therm…
Probing the pairing symmetry of moiré graphene superconductors
Sayak Biswas, Rajdeep Sensarma, Mohit Randeria
The pairing symmetry of magic-angle moiré graphene is a fundamental question that remains unresolved. Combining experimental and theoretical inputs, we constrain the superconducti…
Entanglement Entropy from Correlation Functions of Scalar Fields in and out of Equilibrium
Mrinal Kanti Sarkar, Saranyo Moitra, Rajdeep Sensarma
We show that odd order Rényi entropies of a system of interacting scalar fields can be calculated as the free energy of replicas of the system with additional…
Controlling particle-hole symmetry of fractional quantum hall states in trilayer graphene
Simrandeep Kaur, Harsimran Singh, Kenji Watanabe +5
We present a detailed experimental study of the particle-hole symmetry (PHS) of the fractional quantum Hall (FQH) states about half filling in a multiband system. Specifically, we…
Exploring unconventional superconductivity in PdTe via Point Contact Spectroscopy
Pritam Das, Sulagna Dutta, Saurav Suman +6
Palladium Telluride (PdTe), a non-layered intermetallic crystalline compound, has captured attention for its unique superconducting properties and strong spin-orbit coupling. In th…
Symmetry broken states at high displacement fields in ABA trilayer graphene
Simrandeep Kaur, Unmesh Ghorai, Abhisek Samanta +4
In this Letter, we present a comprehensive study of magnetotransport in high-mobility trilayer graphene (TLG) devices under a transverse displacement field, focusing on symmetry-br…
