The Yang-Baxter integrability of the critical Ising chain
Akash Sinha, Tinu Justin, Pramod Padmanabhan +1
We show that the one dimensional, critical transverse field Ising model is Yang-Baxter integrable. This is done by constructing commuting transfer matrices built out of a -matri…
Non-hermitian integrable systems from constant non-invertible solutions of the Yang-Baxter equation
Somnath Maity, Pramod Padmanabhan, Vladimir Korepin
We construct invertible spectral parameter dependent Yang-Baxter solutions (-matrices) by Baxterizing constant non-invertible Yang-Baxter solutions. The solutions are algebraic…
Off-shell phase diagram of BPS black holes in AdS
Debabrata Sahu, Chandrasekhar Bhamidipati
We construct the off-shell free energy of supersymmetric black holes in AdS, and study the phase diagram in various limiting cases, with particular emphasis on BPS thermodynami…
Majorana fermions solve the tetrahedron equations as well as higher simplex equations
Pramod Padmanabhan, Vladimir Korepin
Yang-Baxter equations define quantum integrable models. The tetrahedron and higher simplex equations are multi-dimensional generalizations. Finding the solutions of these equations…
Spectral representation in Klein space: simplifying celestial leaf amplitudes
Sarthak Duary, Sourav Maji
In this paper, we explore the spectral representation in Klein space, which is the split signature flat spacetime. The Klein space can be foliated into Lorentzian $\mathrm{…
Solving the Yang-Baxter, tetrahedron and higher simplex equations using Clifford algebras
Pramod Padmanabhan, Vladimir Korepin
Bethe Ansatz was discoverd in 1932. Half a century later its algebraic structure was unearthed: Yang-Baxter equation was discovered, as well as its multidimensional generalizations…
ISCOs and the weak gravity conjecture bound in higher derivative theories of gravity
Adrinil Paul, Chandrasekhar Bhamidipati
We study circular orbits of charged particles in spherically symmetric AdS black holes in higher derivative theories of gravity, and their limiting ISCOs (innermost stable circular…
A stabilizer code model with non-invertible symmetries: Strange fractons, confinement, and non-commutative and non-Abelian fusion rules
Tanay Kibe, Ayan Mukhopadhyay, Pramod Padmanabhan
We introduce a stabilizer code model with a qutrit at every edge on a square lattice and with non-invertible plaquette operators. The degeneracy of the ground state is topological…
Statistical ensembles and logarithmic corrections to black hole entropy

In this paper, we consider general statistical ensembles and compute logarithmic corrections to the microcanonical entropy resulting due to thermodynamic fluctuations which are con…

Pavan Kumar Yerra, Chandrasekhar Bhamidipati, Sudipta Mukherji
Using the Bragg-Williams construction of an off-shell free energy we compute the topological charge of the Hawking-Page transition point for black holes in AdS. A computation follo…

Shankhadeep Chakrabortty, Hironori Hoshino, Sanjay Pant +1
In this work, we perform a holographic study to estimate the effect of backreaction on the correlation between two subsystems forming the thermofield double (TFD) state. Each of th…

Nirmalendu Acharyya, Akash Sinha
In a -dimensional Maxwell-Chern-Simons theory coupled with a fermion and a scalar, which has SUSY in absence of the boundary, the insertion of a spatial boun…

In the current manuscript we perform a systematic investigation about the effects of nonlocal interaction to the spread of quantum information in many body system. In particular, w…
Logarithmic corrections to the entropy function of black holes in the open ensemble

An `open' or -ensemble describes equilibrium systems whose control parameters are chemical potential , pressure and temperature . Such an unconstrained ensemble…
Novel logarithmic corrections to black hole entropy
Aritra Ghosh, Sudipta Mukherji, Chandrasekhar Bhamidipati
For a thermodynamic system, apart from thermal fluctuations, there are also fluctuations in thermodynamic volume when the system is in contact with a volume reservoir. For the case…

Nirmalendu Acharyya, Mahul Pandey, Sachindeo Vaidya
The Yang-Mills matrix model admits self-dual and anti-self-dual instantons. When coupled to flavors of massless quarks, the Euclidean Dirac equation in an instanton b…
